TXA Niacinamide Toning Shot 99 Serum
TXA Niacinamide Toning Shot 99 Serum
Product Description
A 4th-generation spicule serum from APRILSKIN that targets dark spots, uneven tone, and enlarged pores using 99% high-purity Tranexamic Acid (3%) and Niacinamide (5%). The lightweight, jelly-like "Step Zero" booster delivers actives through micro-spicules 25 times smaller than pores for enhanced absorption, plus milk exosomes, alpha-arbutin, and a peptide for added brightening and barrier support.
โจ Texture & Feel
Liquid Spicule Technology
Micro-spicules 25 times smaller than pores act as natural carriers, claiming 220% enhanced absorption of TXA, niacinamide, and exosomes deep into the skin.
99% High-Purity TXA
Pharmaceutical-grade tranexamic acid at 3% targets melasma, post-inflammatory hyperpigmentation, and uneven tone at the source by inhibiting melanin production.
Step Zero Skin Booster
Designed as the first step after cleansing to prep skin and amplify absorption of every product layered after, including moisturizer and sunscreen.
Milk Exosomes & Peptide
Bioactive milk exosomes and sh-Oligopeptide-1 (EGF) work to refine pores, boost firmness, and accelerate skin renewal alongside the brightening complex.
๐ก๏ธ Safety & Compatibility
Free of fatty acids, esters, and oils that feed malassezia yeast. Verified safe by SkinSort.
No added fragrance, essential oils, or artificial colorants โ the pink hue is from raw cyanocobalamin (B12).
No animal testing and no oxybenzone, octinoxate, or microplastic exfoliants harmful to marine ecosystems.
Contains tranexamic acid and betaine salicylate (a BHA derivative). Consult your OB-GYN before use during pregnancy or breastfeeding.
Brand confirms a mild tingle on application as actives react. Not irritation โ but patch test if your skin is reactive.
Pairs well with hydrators, peptides, and SPF. Avoid layering with high-strength retinol or pure ascorbic acid in the same routine.
๐ฌ Ingredient Breakdown
๐ง Tranexamic Acid 3% Proven
A synthetic amino-acid derivative of lysine, used at 99% high-purity grade. Inhibits the plasminogen-keratinocyte pathway that triggers melanin overproduction โ particularly effective for melasma and UV-induced pigmentation.
- Source: A 2017 review in Indian Journal of Dermatology found topical TXA significantly reduces melasma severity scores after 12 weeks.
- Source: Works at the source of pigmentation, unlike vitamin C which mainly addresses surface oxidation.
๐ Niacinamide 5% Proven
Vitamin B3 that strengthens the skin barrier, regulates sebum, fades dark spots by blocking melanosome transfer, and reduces redness โ the gold-standard multitasker.
- Source: 5% concentration is clinically validated for visible reduction in hyperpigmentation, fine lines, and pore appearance (Hakozaki et al., 2002).
- Source: Synergizes with TXA โ both target melanin via different pathways for compounded brightening effect.
๐ฌ Hydrolyzed Sponge (Spicules) ~1-2% Promising
Marine-sourced micro-needles 25ร smaller than skin pores. They create temporary microchannels in the stratum corneum to amplify the penetration of TXA, niacinamide, and exosomes.
- Source: APRILSKIN's clinical trial (P&K Skin Research Center) reports 220% enhanced active absorption.
- Source: Spicule technology is also used in dermatology clinics for at-home microneedling effects without bleeding.
๐ฅ Milk Exosomes <1% Promising
Nano-vesicles derived from milk that carry growth factors, peptides, and lipids. Emerging research suggests they support cell-to-cell communication, accelerate barrier repair, and reduce visible signs of aging.
- Source: A 2022 study (Pharmaceutics journal) showed milk-derived exosomes promote keratinocyte proliferation and wound healing.
๐ธ Alpha-Arbutin ~0.5-1% Proven
A stable, water-soluble derivative of hydroquinone that inhibits tyrosinase โ the enzyme responsible for melanin synthesis. Gentler than hydroquinone, with no rebound pigmentation risk.
- Source: Studies indicate alpha-arbutin is effective at 1-2% for visible dark-spot reduction within 8-12 weeks.
- Source: Works synergistically with niacinamide and TXA in this trio-active formula.
๐งฌ sh-Oligopeptide-1 (EGF) 0.10-0.15% Promising
A bioengineered Epidermal Growth Factor peptide that signals fibroblasts to produce collagen and accelerates skin renewal. Helps refine texture and reduce post-acne marks.
- Source: A 2012 clinical study reported significant improvement in fine lines, texture, and pore size with topical EGF over 3 months.
๐ Betaine Salicylate (BHA) ~0.5% Proven
A gentle, plant-derived BHA that exfoliates inside pores, reduces blackheads, and improves the absorption of brightening actives. Less irritating than traditional salicylic acid.
- Source: Korean clinical research shows betaine salicylate at 4% performs comparably to 2% salicylic acid with lower irritation scores.
๐ง Sodium Hyaluronate & Panthenol <1% Proven
A hydration duo โ sodium hyaluronate binds water at 1000ร its weight, while panthenol (provitamin B5) soothes inflammation and reinforces the moisture barrier disrupted by actives.
- Source: Counterbalance any drying effect from BHA + TXA combination, keeping skin plump and calm.

๐ Where It Fits in Your Routine
APRILSKIN brands it as a "Step Zero" booster โ apply right after cleansing or toner to prep skin and boost absorption of everything that follows.
๐ How to Use
Cleanse & Tone
Wash your face and apply your usual hydrating toner. Skin should be slightly damp, not dripping.
Dispense 1 Pump
One pump (about 1ml) is enough for the full face and neck. The jelly texture spreads easily.
Pat into Skin
Avoid the eye and mouth area. Gently pat โ don't rub โ until fully absorbed. A mild tingle is normal.
Layer & Lock In
Follow with serum, moisturizer, and SPF in the morning. Use morning and night for best results.
Patch Test First
If you have sensitive skin, apply to inner forearm for 24 hours before facial use due to spicule activity.
๐ค Who Is It For?
โ Perfect for you if:
- You have dark spots, melasma, or post-acne hyperpigmentation
- You want a multi-active brightening serum without retinol or hydroquinone
- You have visible pores or uneven texture
- You enjoy K-beauty layering and "skin booster" steps
- You have oily, combo, or normal skin and want a non-greasy active
- You want an alternative to AHA/BHA-heavy exfoliating serums
โ Consider alternatives if:
- You're pregnant or breastfeeding (consult your doctor first)
- You have very reactive or rosacea-prone skin (spicule tingling may be uncomfortable)
- You're already using strong retinoids or prescription depigmenting agents
- You have very dry skin and need a richer hydrator instead
- You dislike any tingling or initial sensation on application
- You're sensitive to niacinamide (rare but possible)
๐ฏ Skin Type Compatibility
Lightweight jelly absorbs quickly, niacinamide regulates sebum, BHA refines pores. Won't add shine or weight.
Glycerin and HA provide hydration, but layer with a richer moisturizer afterward โ actives may feel slightly dehydrating alone.
Balances oily T-zones while delivering hydration to drier cheeks. Ideal multi-zone treatment serum.
Hypoallergenic-tested and fragrance-free, but spicules cause noticeable tingling. Patch test 24 hours first.
Fungal-acne safe, non-comedogenic, niacinamide + BHA fight breakouts and fade post-acne marks at the same time.
Adenosine, EGF peptide, and exosomes support firmness and renewal alongside age-spot fading.

โ๏ธ Pros & Cons
โ Praised
- Triple-active formula (TXA + Niacinamide + Alpha-Arbutin) for layered brightening
- 99% high-purity TXA absorbs cleanly with no sticky finish
- Spicule technology delivers visible pore refinement
- Fragrance-free, fungal-acne safe, hypoallergenic-tested
- Lightweight jelly suits all climates and layers under SPF
- Visible glow from week one for most users
- Vegan-leaning formula with no harsh alcohols
โ Criticized
- 30ml feels small for the price point (~$28-35 USD)
- Tingling sensation polarizes โ fine for some, uncomfortable for others
- Pump dispenser can release inconsistent amounts
- Stubborn melasma needs 8+ weeks of consistent use
- Pregnancy use requires medical clearance
- Vitamin C content is too low to function as a true antioxidant
๐ฐ Budget-Friendly Alternatives (Dupes)
Higher concentrations of both actives (10% NIA + 4% TXA + 2% arbutin) at a lower price. No spicules, watery texture instead of jelly. Best dupe for hyperpigmentation goals.
Even cheaper alternative with similar TXA + niacinamide combo plus 2% arbutin. Larger 33ml bottle, but lacks exosomes, peptides, and spicule delivery system.
Higher 20% niacinamide with TXA, glutathione, and centella. Different active emphasis โ leans on niacinamide, no spicules or alpha-arbutin.
Single-active brightening serum at lowest price. Simpler formula โ no TXA, no niacinamide, no exosomes. Best as a basic add-on, not a direct replacement.

โ Frequently Asked Questions
Caution advised. The serum contains tranexamic acid (a prescription medication in some countries) and betaine salicylate (a BHA derivative). While topical use is generally considered low-risk, pregnancy guidelines vary. Consult your OB-GYN or dermatologist before use during pregnancy or breastfeeding. Many practitioners recommend pausing brightening actives entirely during this period.
Yes. The formula is verified fungal-acne safe by SkinSort and contains no fatty acids, esters, oils, or polysorbates that feed Malassezia yeast. Safe to use if you struggle with fungal acne, sebum-related breakouts, or pityrosporum folliculitis.
Pairs well with most actives, but with caveats. The serum already contains BHA (betaine salicylate) and a trace of vitamin C, so adding additional exfoliants may cause sensitivity. Use retinol on alternate nights โ apply Toning Shot 99 in the morning, retinol at night. Avoid layering with high-strength pure ascorbic acid simultaneously to prevent destabilization. Always finish AM routines with SPF.
Best suited for oily, combination, and acne-prone skin types dealing with dark spots, post-inflammatory hyperpigmentation, melasma, or enlarged pores. Normal and mature skin also benefit from the firming peptide and exosomes. Dry skin can use it but should follow with a richer moisturizer. Very sensitive or rosacea-prone skin should patch test first due to spicule activity.
Most users report a visible glow within the first week. APRILSKIN's clinical claim is "improves uneven skin tone after 2 weeks." Dark spots and post-acne marks typically begin fading at the 4-6 week mark, with significant melasma reduction at 8-12 weeks. Consistency is critical โ twice daily application gives the best results.
APRILSKIN markets it as a "Step Zero" booster โ apply right after cleanser and toner, before any serum or essence. The spicules act as a delivery enhancer, so anything layered after will absorb more deeply. Order: Cleanser โ Toner โ Toning Shot 99 โ Serum/Essence โ Moisturizer โ SPF (AM only).
No. Comedogenic rating is 1/5. The water-based jelly formula contains no oils, butters, or known pore-clogging ingredients. It's actually pore-refining thanks to niacinamide, BHA, and the spicule exfoliation effect. Safe for acne-prone, blackhead-prone, and oily skin.
The Period After Opening (PAO) is 12 months. Use within a year of first opening to ensure the tranexamic acid, niacinamide, vitamin C, and exosomes remain at full potency. Store in a cool, dry place away from sunlight. With twice-daily use, the 30ml bottle typically lasts 6-8 weeks.
The tingling is caused by hydrolyzed sponge spicules โ micro-needles 25ร smaller than pores that create temporary microchannels for active delivery. This is normal and expected, not a sign of irritation. The brand confirms it's a "natural reaction as ingredients react with skin." If burning or redness lasts more than 30 minutes, discontinue and patch test.
The Toning Shot 99 Serum (this product) is the high-concentration "Step Zero" treatment with spicules. The Pink Milky Toner is a follow-up creamy hydrating toner with the same TXA + niacinamide complex but no spicules and a softer milky texture. Use them together: Serum first, then Milky Toner to seal in actives and add hydration.
Verdict: The APRILSKIN TXA Niacinamide Toning Shot 99 Serum is one of the most innovative brightening serums in K-beauty right now, combining 99% high-purity tranexamic acid, niacinamide, alpha-arbutin, milk exosomes, and EGF peptide in a single jelly-textured formula. The spicule delivery system is a genuine differentiator โ at-home microchanneling that boosts active penetration without irritation for most users. Best for oily/combo/acne-prone skin tackling stubborn dark spots, melasma, or post-acne marks. Mild sensitive types should patch test, and pregnant users should consult their doctor. The 30ml size is small relative to its mid-range price, but consistency and a multi-target ingredient stack justify the spend for serious hyperpigmentation goals.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging ยซpromisesยป it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.

Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
