Purito TXA 6 Niacinamide 10 Retinal Serum Review 2026

Dark spots do not disappear overnight. Anyone who has stared at old acne marks in the bathroom mirror knows this pain well. So when a Korean brand promises a 16% triple active formula for around twenty dollars, curiosity kicks in fast.

Purito Seoul launched the TXA 6 Niacinamide 10 Retinal Serum with a bold claim. One drop, triple effect, dark spot out. That is a lot of confidence packed into a 30 ml bottle.

I bought this serum with my own money and used it every night for eight weeks. I tracked my skin with photos. I noted the good days and the frustrating ones.

In A Nutshell:

• The formula is genuinely strong for the price. You get 6% tranexamic acid, 10% niacinamide, and 25 ppm retinal in one bottle for about $17.99 on Amazon. Most Western brands charge double for less active content.
• Results appear slowly but they do appear. My post acne marks looked visibly lighter around week six. Older sun spots on my cheekbones faded less. Patience matters more than expectations here.
• The texture divides people. This serum feels slightly gel like and sticky on application. It settles once a moisturizer goes on top, but oily skin types may find the finish tacky in humid weather.
• The retinal dose is very low. At 25 ppm, that works out to roughly 0.0025% retinal. This is a supporting player, not a wrinkle treatment. Do not buy this expecting retinal results.
• Sensitive skin tolerates it well. No synthetic fragrance, no essential oils, plus ceramide NP, centella, and allantoin for buffering. I had zero stinging across eight weeks.
• Sunscreen is mandatory. Skipping SPF while using this serum wastes your money completely. Pigmentation returns faster than it fades.

Purito Seoul sits in an interesting spot in Korean skincare. The brand built its reputation on simple, sensitive skin friendly formulas. Then it rebranded and started pushing higher concentration actives.

This serum represents that shift. It is the most aggressive product Purito has released so far, at least on paper.

The bottle holds 30 ml, which is 1.01 fluid ounces. Purito lists it at $25.00 on the official site. Amazon usually sells it lower, sitting around $17.99 with a subscribe and save coupon on top.

The star ingredients are easy to read from the name. Tranexamic acid at 6%, niacinamide at 10%, and retinal at 25 ppm. Purito markets the combined active load as 16% triple active.

Manufacturing happens in Korea through Kolmar, one of the largest cosmetic manufacturers in the country. HINATURE Inc. handles the brand side.

The product carries vegan and cruelty free certification. There is no synthetic fragrance in the ingredient list, which matters a lot for reactive skin.

One detail catches most buyers by surprise. The serum contains suspended capsules that need shaking before use. Purito recommends shaking the bottle roughly 35 times to disperse them properly.

Those capsules carry the retinal and the pink tint from cyanocobalamin, which is vitamin B12. The color fades over time with light exposure. Purito confirms this does not affect performance.

Unboxing Experience And First Impressions

The package arrived in a slim white carton with minimal print. No plastic wrap, no excess filler, no glossy foil. Purito clearly leans into the earth conscious angle.

Inside sits a frosted glass bottle with a black dropper cap. The glass feels heavier than expected for this price point. It has a satisfying weight in the hand.

The dropper is standard rubber bulb style. It picks up enough product for the full face in one squeeze, though I usually go for two.

My first look at the liquid surprised me. The serum sat in two visible layers, a milky white base with tiny orange pink beads floating throughout. It looks a bit like a science experiment.

Shaking the bottle changes everything. After about thirty shakes the whole thing turns a soft peachy pink and looks completely uniform. The transformation is oddly enjoyable.

The first drop on my hand felt thicker than a typical watery essence. Not quite lotion, not quite serum. Somewhere in between.

Scent is almost absent. There is a faint powdery smell from the niacinamide, nothing more. People sensitive to fragrance will be relieved.

The carton includes a full ingredient list in English and Korean, plus usage steps. The batch code sits on the bottom of the box and on the bottle label.

One small complaint straight away. The dropper cap does not seal tightly enough for travel. I would not toss this in a checked bag without wrapping it.

Key Ingredients Explained Simply

Let us break down what actually works in this bottle.

Tranexamic acid at 6% is the headline. This ingredient blocks the communication between UV damaged skin cells and melanocytes, the cells that produce pigment. Less signal means less new pigment.

Clinical work on topical tranexamic acid usually studies concentrations between 2% and 5%. Purito went to 6%, which sits at the higher end of what brands use.

Tranexamic acid works especially well on melasma and post inflammatory hyperpigmentation. It is one of the few brightening ingredients dermatologists reach for with stubborn hormonal pigmentation.

Niacinamide at 10% does several jobs at once. It slows the transfer of melanin to surface skin cells. It supports the skin barrier. It helps regulate oil production.

Ten percent is a high dose. Some people report flushing or irritation at this level, though the buffering ingredients here help a lot.

Retinal at 25 ppm is where I have to be honest with you. That converts to roughly 0.0025%. This is a trace amount.

Retinal, also called retinaldehyde, converts to retinoic acid faster than retinol does. It is genuinely a good ingredient. But at this dose it functions as a mild support act, not a treatment.

The supporting cast is strong. Glutathione, ceramide NP, centella asiatica, allantoin, bisabolol, tocopherol, and adenosine all appear in the list.

Hydroxydecyl ubiquinone is a stable coenzyme Q10 derivative that adds antioxidant protection. Lactococcus ferment lysate supports barrier repair.

There is no alcohol denat and no essential oil. That is a thoughtful call for a product this concentrated.

Texture, Scent, And How It Feels On Skin

Texture is the most debated part of this serum online. I understand why.

Fresh from the dropper, the liquid feels slightly slippery and gel like. It spreads easily across the face with light pressure.

Absorption takes about sixty to ninety seconds on my normal to dry skin. It leaves a faint tacky film behind.

That tackiness is the sticking point for many users. Reddit threads about this serum bring it up constantly. Some people love the cushiony feel, others find it uncomfortable.

The stickiness disappears completely once you apply moisturizer. This is not a product you want to leave bare on the skin.

I tested it under makeup twice. Both times my foundation applied fine, though I waited a full five minutes first. Rushing this step caused slight patchiness on my nose.

Pilling happened once. I had layered it over a silicone heavy primer type product, which was my mistake. On clean skin after toner, it behaved perfectly.

The finish looks slightly dewy, not greasy. There is no white cast and no visible residue after a minute.

Scent stays neutral throughout. I detect a very light powdery note that fades within seconds.

Oily skin readers should note one thing. In humid summer weather this serum feels heavier than in dry winter air. A gel moisturizer on top handles it fine.

How To Use It In Your Skincare Routine

Purito gives clear instructions and they are worth following.

Start by shaking the bottle around 35 times. This disperses the capsules. Skipping this step means uneven active delivery.

Apply after cleansing and toner. This serum works as your first treatment step, before heavier essences or creams.

Two to three drops cover the full face. More does not mean faster results. It only means the bottle empties sooner.

Pat gently rather than rubbing. Patting helps the film settle evenly and reduces the sticky feeling.

Follow with a moisturizer. Every single time. The formula is not hydrating enough to work alone.

Sunscreen in the morning is not optional with this product. Tranexamic acid and niacinamide both fight UV triggered pigment. Unprotected sun exposure cancels their work.

I used it at night for the first two weeks, then moved to twice daily. My skin handled both fine.

Avoid layering it directly with strong exfoliating acids in the same step. Alternate nights instead. The retinal content is low, but 10% niacinamide plus a strong AHA can irritate.

It layers well with hyaluronic acid, peptides, and ceramide creams. I paired it with a simple ceramide moisturizer and had no issues.

Storage matters slightly. Keep it away from direct light. The pink color fades faster in a bright bathroom.

My Eight Week Results On Real Skin

I have combination skin with post acne marks on both cheeks and a few sun spots along my cheekbones. I am in my thirties.

Here is what happened week by week.

Weeks one and two brought nothing visible. My skin felt slightly smoother in the morning, which I credit to the ceramides. No irritation, no purging.

Week three showed an improvement in overall brightness. Not dramatic. More like my skin looked less tired in photos.

Weeks four and five were the turning point for texture. My skin felt noticeably softer and my pores looked slightly refined. Niacinamide usually delivers this around this timeline.

Week six is when the marks started shifting. Two red post acne spots on my left cheek faded to a much lighter pink. This was the first change I could see clearly in side by side photos.

Weeks seven and eight continued that trend. The newer marks kept lightening. My overall tone looked more even under natural light.

Now the honest part. My older sun spots barely moved. Those deep, well established brown patches on my cheekbones looked roughly the same at week eight as week one.

This matches what tranexamic acid tends to do. It performs best on newer, inflammation driven discoloration. Old sun damage needs stronger intervention.

I also noticed no change at all in fine lines. Given the retinal dose, that was expected.

Overall, I would rate the pigmentation improvement as modest but real. Around a 30% improvement on newer marks.

What This Serum Does Not Do Well

Every review should include this section. Here are the genuine weaknesses.

The retinal content is essentially marketing. At 25 ppm, this serum will not deliver retinoid benefits. If wrinkles or texture renewal are your goal, buy a dedicated retinal product instead.

The stickiness is real and it bothers some people. I adapted after a week. My partner tried it twice and refused to continue because of the finish.

It does not hydrate enough on its own. Dry skin types will feel tight without a moisturizer on top. This is a treatment step only.

Results on deep sun spots are weak. Melasma and post acne marks respond better. Old, deep pigmentation may need professional treatment.

The dropper cap seals poorly. Mine leaked slightly when stored on its side. Keep it upright.

Some users report congestion. A handful of reviews mention small breakouts around week two or three. Caprylic capric triglyceride sits fairly high in the list, which may bother very acne prone skin.

The pink color fades. Purito says this does not affect performance, and I believe them. Still, watching your serum turn beige is slightly unsettling.

Availability fluctuates. This product sells out often on Amazon and the official site. Restocks can take weeks.

None of these issues make the serum bad. They simply set realistic expectations before you spend money.

Pros And Cons

Pros

• High active concentration at a low price. Getting 6% tranexamic acid and 10% niacinamide for under twenty dollars is genuinely rare.
• Gentle formula for a strong product. No synthetic fragrance, no essential oils, no alcohol denat, plus ceramides and centella for buffering.
• Visible improvement on post acne marks. My newer discoloration lightened clearly by week six.
• Layers well under makeup and other products. Very little pilling on clean skin.
• Vegan and cruelty free certification. A plus for buyers who care about sourcing.
• Quality glass packaging. The bottle feels far more premium than the price suggests.

Cons

• Retinal dose is too low to matter. At 25 ppm it contributes almost nothing measurable.
• Sticky finish that requires a moisturizer. Oily skin in humid climates may struggle.
• Slow results on older sun damage. Do not expect miracles on deep pigmentation.
• Requires shaking before every use. Minor, but easy to forget.
• Dropper cap does not seal for travel. Risk of leaking in a bag.
• Stock issues. Frequently unavailable during sales periods.

Price And Value For Money

Purito lists this serum at $25.00 for 30 ml. Amazon commonly discounts it to around $17.99, with an extra 5% coupon on subscribe and save.

That works out to roughly $0.60 per milliliter at full price and about $0.43 at the Amazon price.

Compare that to Western brands. A comparable tranexamic acid serum from a US skincare label typically runs $28 to $90 for the same size.

The value case here is strong. You are paying budget prices for concentrations that sit at the upper end of what is commonly formulated.

Bottle life depends on usage. Using two drops once daily, mine lasted about ten weeks. Twice daily would cut that to roughly six weeks.

That places the monthly cost around $8 to $12. Reasonable for a treatment serum.

There is one caveat worth mentioning. The retinal content adds nothing meaningful to the value, so mentally price this as a tranexamic acid plus niacinamide serum.

Judged that way, it still wins. Very few products pair 6% TXA with 10% niacinamide at this price.

Amazon pricing fluctuates. I have seen it drop below $16 during major sale events. Setting a price alert is worthwhile.

How It Compares To Other Tranexamic Acid Serums

Let us put this serum against three popular competitors.

Naturium Tranexamic Topical Acid 5% uses a lower TXA dose but adds kojic acid and niacinamide. It costs around $20 for 30 ml. The texture is lighter and less tacky. Naturium is the better pick for oily skin.

SKIN1004 Tone Brightening Capsule Ampoule combines niacinamide with tranexamic acid and centella. It feels far more lightweight and absorbs faster. Concentrations are lower, so results come slower.

Beauty of Joseon Glow Deep Serum takes a different route with alpha arbutin and rice ferment. It hydrates far better and costs less. Brightening is gentler and slower.

Against all three, Purito offers the highest total active load. That is its real advantage.

Where Purito loses is cosmetic elegance. Naturium and SKIN1004 both feel nicer on the skin.

Where Purito wins is potency per dollar. If you want the strongest formula in this price bracket, Purito takes it.

For melasma specifically, I would rank Purito first among these four. The 6% tranexamic acid concentration matters for that concern.

For general dullness with sensitive skin, Beauty of Joseon is the friendlier entry point.

Safety, Irritation, And Patch Testing

Ten percent niacinamide sounds intimidating to some readers. Let us address that.

Niacinamide flushing typically happens with poorly purified niacinamide or with very reactive skin. Purito buffers this well with ceramide NP, allantoin, bisabolol, and centella.

I experienced no stinging, no redness, and no flushing across eight weeks. My skin is mildly reactive.

Still, patch testing makes sense. Apply a small amount behind the ear or on the inner forearm for three consecutive days.

Start with every other night if your skin runs sensitive. Build to daily use over two weeks.

The retinal content is low enough that purging is unlikely. Any breakouts in the first month are more likely a congestion response than purging.

Purito advises against use during pregnancy or breastfeeding without a doctor consultation. This is standard advice for any retinoid containing product, even at trace levels.

Avoid contact with eyes. Tranexamic acid can sting the eye area.

Do not apply to broken or irritated skin. Wait until the barrier recovers.

Daily sunscreen is required. Both the retinal and the active brightening ingredients increase the importance of UV protection.

If irritation appears and persists, stop use and speak to a dermatologist.

Who Should Buy It And Who Should Skip It

Buy this serum if you deal with post acne marks, melasma, or general dullness. It targets exactly those concerns.

Buy it if you have sensitive skin and previous brightening products stung. This formula is unusually gentle for its strength.

Buy it if you want maximum active concentration on a small budget. Nothing at this price beats it on paper.

Buy it if you already have a solid moisturizer and sunscreen routine. This works as an addition, not a replacement.

Skip it if you want retinal benefits. The dose is far too low. Buy a real retinal serum instead.

Skip it if you hate tacky textures. This one will annoy you daily.

Skip it if your main concern is deep, decades old sun damage. You need stronger tools.

Skip it if you are very acne prone and react to emollient esters. The formula may congest you.

Skip it also if you do not wear sunscreen. That is not a criticism of you. It simply means this product cannot deliver what it promises without UV protection.

The Purito TXA 6 Niacinamide 10 Retinal Serum earns a solid recommendation with clear caveats.

As a tranexamic acid and niacinamide treatment, it performs well and costs very little. My post acne marks visibly faded within six weeks. My skin tone looked more even by week eight.

The formula is thoughtfully built. Ceramides, centella, glutathione, and antioxidants support the actives instead of just padding the list.

The packaging feels premium. The scent is neutral. Sensitive skin tolerates it.

The retinal claim is the weak point. At 25 ppm, it belongs in the fine print rather than the product name.

The sticky texture will divide readers. Try it and decide for yourself.

My rating sits at 4.2 out of 5. Strong value, honest formulation, modest but real results.

If you want brighter, more even skin without spending fifty dollars, this bottle deserves a place on your shelf. Just bring realistic expectations and a good sunscreen.

Frequently Asked Questions

How long does the Purito TXA serum take to work?

Most users see brightness improvements around week three or four. Visible fading of post acne marks usually appears between weeks six and eight. Deep sun spots take longer and may need additional treatments.

Can I use this serum with vitamin C?

Yes, though I recommend separating them. Use vitamin C in the morning and the Purito serum at night. This reduces any risk of irritation and lets each ingredient work at optimal pH.

Does this serum cause purging?

Purging is unlikely at 25 ppm retinal. Some users report small breakouts in the first few weeks, which is more likely a reaction to the emollient content than true purging. Reduce frequency if this happens.

Is it safe for pregnancy?

Purito advises consulting a doctor before use during pregnancy or breastfeeding. The product contains retinal, which falls under the retinoid family. Most doctors recommend avoiding all retinoids during pregnancy.

Why does the pink color fade?

The pink tint comes from cyanocobalamin, which is vitamin B12. Light exposure fades the color over time. Purito confirms this does not affect product performance or safety.

Do I really need to shake it 35 times?

Yes, shaking matters. The capsules holding the retinal and B12 settle when the bottle sits still. Shaking disperses them evenly so each application delivers consistent actives.

Can oily skin use this serum?

Oily skin can use it, though the tacky finish may feel uncomfortable in humid weather. Apply a lightweight gel moisturizer on top. Some oily skin users prefer a lighter alternative like Naturium.

Is it better than Beauty of Joseon Glow Deep Serum?

Purito delivers higher active concentrations and works faster on pigmentation. Beauty of Joseon hydrates better and feels lighter. Choose Purito for targeted dark spots and Beauty of Joseon for general glow.

How often should I apply it?

Start with every other night for two weeks. Move to nightly use once your skin adjusts. Twice daily use is possible for most people, but a bottle will empty in about six weeks at that rate.

Where can I buy the authentic product?

Amazon, the official Purito Seoul website, and authorized Korean beauty retailers all stock genuine product. Check batch codes and avoid unusually cheap third party sellers to prevent counterfeits.
