19% Dark Spot Serum
19% Active Serum
Dark Spot & Brightening
The highest-concentration brightening serum in the DAMTIX line. 15% niacinamide, 3% Matrixyl 3000, 1% green tea callus — plus tranexamic acid and stable vitamin C. Five brightening pathways. One formula.

The Forbidden
Formula.
Most serums dilute their actives to stay safe. Damtix 19% Active Serum doesn't. Uncompromising potency for stubborn dark spots that refuse to fade.
DAMTIX Formula Philosophy
The Forbidden Formula:
Damtix 19% Active Serum
Uncompromising potency for stubborn dark spots. Where other brands cap niacinamide at 5–10%, Damtix pushes to 15%. Where Matrixyl 3000 is a trace ingredient elsewhere, we put it at a clinically meaningful 3%. Add tranexamic acid and stable vitamin C — and the result is a formula that works where nothing else has.

Application Range
4 Concerns. 1 Serum.
Every Type of Dark Spot Covered.
Hyperpigmentation doesn't have a single cause — and a formula this concentrated shouldn't have a single use. The 19% Active Serum works across four of the most stubborn pigmentation concerns.
01
Sun Spots & UV Damage
Years of sun exposure accumulate in the skin as persistent melanin deposits. Niacinamide at 15% interrupts melanin transfer while Matrixyl supports the structural repair underneath.
02
Melasma & Hormonal Spots
Hormonally triggered, notoriously hard to fade. The anti-inflammatory stack — niacinamide + green tea callus — tackles the oxidative stress that keeps melasma recurrent.
03
Post-Acne Marks
Inflammation leaves behind dark signals in the skin. Niacinamide blocks new pigment from forming; Matrixyl smooths the textural aftermath. Both work together.
04
Dark Circles (Periorbital)
Thin skin under the eyes reacts to chronic inflammation and poor circulation. The brightening and peptide complex support visible improvement with consistent use.
Formulation Tip
Too strong? Blend it with Repair Cream.
19% is a high-potency formula. If your skin is new to actives, mix one pump of Dark Spot Serum into your Repair Cream on the lid — the ceramide base will buffer the concentration while keeping the actives effective. Scale up over 2–3 weeks.
Stubborn spots don't
need more tries.
They need more actives.

Application
How to Use
Step 01
Cleanse & Tone
Apply on clean, dry skin after toner. Excess moisture can dilute active concentration.
Step 02
Dispense 2–3 Drops
Apply directly to dark spots or blend across the full face. Press gently — do not rub.
Step 03
Let Absorb (60 sec)
Allow the serum to fully absorb before the next step. Rushing disrupts active penetration.
Step 04
Seal with Repair Cream
Lock actives in with DAMTIX Repair Cream. Or blend the two together for a buffered, beginner-friendly application.
AM: Apply SPF 30+ after serum. Consistent sun protection prevents UV from reversing the brightening work. | PM: Ideal window for active absorption. Use nightly for best results.

Aestheticians' Tips for Treating Dark Spots
| Consistency over intensity | Pigment fading is cumulative. Daily use for 8–12 weeks outperforms sporadic high-intensity treatments. Build the habit first. |
| SPF is non-negotiable | Any brightening active becomes irrelevant without daily sun protection. UV exposure re-triggers melanin production faster than actives can inhibit it. |
| Start with spot treatment | New to 15% niacinamide? Apply to target areas only for the first two weeks. Let the skin adjust before full-face use. |
| Buffering with Repair Cream | Mix 1 pump serum + 1 pump Repair Cream on the product lid. Ceramide base buffers sensitivity while keeping actives effective. |
| Treat dark circles gently | Use ring finger only for periorbital application. The skin under the eyes is 40% thinner — half a pump is sufficient. |
| Pair with Matrixyl benefit | The peptide in this formula also supports collagen. Don't limit it to pigmentation — it's also working on texture and density simultaneously. |
Formula Breakdown
What's Inside — And Why It Works
| Ingredient | Concentration | Function |
|---|---|---|
| Niacinamide | 15% | Inhibits melanosomes transferring pigment to surface skin cells. Simultaneously reduces pore size, controls sebum, and supports barrier integrity. Clinical studies show visible brightening from 8 weeks at this concentration. |
| Matrixyl 3000 (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7) |
3% | The most clinically studied collagen-stimulating peptide complex. Tripeptide-1 signals collagen I, III, and IV synthesis; Tetrapeptide-7 reduces inflammatory cytokines that trigger post-acne darkening. Works on the structural layer directly below the pigmentation problem. |
| Green Tea Callus Extract | 1% | Plant stem cell technology. High antioxidant activity neutralizes free-radical damage that triggers melanin overproduction. Anti-inflammatory properties reduce redness and post-acne hyperpigmentation at the cellular level. |
| Tranexamic Acid | Active | A pharmaceutical-grade skin brightener originally used in oral form for melasma treatment. Inhibits the interaction between keratinocytes and melanocytes — blocking the signal chain that produces excess pigment at the source. Particularly effective on melasma and hormonal spots resistant to niacinamide alone. Works synergistically with 15% niacinamide for compounded brightening. |
| 3-O-Ethyl Ascorbic Acid | Active | The most stable form of vitamin C for topical use. Converts to L-ascorbic acid in skin — neutralizing free radicals, inhibiting tyrosinase (the key enzyme in melanin production), and stimulating collagen synthesis. Works alongside niacinamide and tranexamic acid as a three-pathway brightening system. |
| Adenosine | Standard | Anti-aging, soothing. Supports cellular repair and reduces visible fine lines. Provides calming buffer for skin adjusting to the high-potency brightening stack. |
| Hydrolyzed Lupin Protein | Standard | Plant-derived protein hydrolysate that supports skin density and surface texture. Complements Matrixyl 3000's structural work at the surface level, improving skin firmness and luminosity. |
| Panthenol | Standard | Pro-Vitamin B5. Hydrates, soothes, and accelerates surface repair. Provides a calming layer that supports the skin while the high-concentration brightening actives do their work. |
Caution & Usage Notes
Patch test recommended for sensitive skin. Avoid direct contact with eyes. Discontinue use if irritation or excessive redness occurs. Contains high-concentration niacinamide — start with spot treatment if new to actives, and scale to full-face use gradually. Always apply broad-spectrum SPF 30+ in the morning when using this serum. Keep out of reach of children. Store below 25°C, away from direct sunlight.
