LAYERLAB Dark Spot Serum 0.94 fl oz, 3% Tranexamic Acid & 7% Niacinamide for Even, Brighter Skin

LAYERLAB Dark Spot Serum is a lightweight daily serum combining 3% tranexamic acid and 7% niacinamide to visibly even skin tone and reduce the appearance of dark spots and post-blemish marks.

This targeted tone-correcting formula blends a 13% active complex—including two stabilized vitamin C forms—with skin-soothing ingredients to help brighten dull-looking skin and minimize discoloration without fragrance. Designed for layering under moisturizer, the serum absorbs quickly so you can keep your routine simple: apply 2–3 drops after toner in morning or evening and follow with sunscreen during the day to protect results.

How does this serum address dark spots and uneven tone?

The serum combines tranexamic acid and a high concentration of niacinamide to target the look of hyperpigmentation from multiple angles. Two forms of stabilized vitamin C support a brighter appearance while antioxidants help protect the skin’s visible tone.

• 3% tranexamic acid to target discoloration pathways
• 7% niacinamide to improve tone uniformity and skin texture
• 2% ascorbyl glucoside + 1% ethyl ascorbic acid for antioxidant brightening
• Contains vitamin E and carnosine to support overall skin comfort

What evidence supports its effectiveness?

In a 4-week clinical evaluation with 22 participants, measurable improvements were observed for skin melanin index and visible discoloration. Users also saw reduced visible redness, indicating the formula targets multiple signs of uneven-looking skin without causing irritation in sensitive-skin testing.

• 15.53% average improvement in skin surface melanin index in 4 weeks
• 5.28% average improvement in visible dark spots and discoloration
• 19.11% average improvement in visible redness after 4 weeks
• 0.00 irritation score in a sensitive-skin patch test; suitable for acne-prone skin

How should I use the serum in my routine for best results?

Apply a few drops after cleansing and toning, both morning and evening, then layer your moisturizer on top. Because the serum works on visible tone, daytime sunscreen is important to protect results and prevent new discoloration.

• Use 2–3 drops after toner, AM and/or PM
• Follow with moisturizer; apply sunscreen during daytime use
• Lightweight texture supports easy layering under other products
• Consistent daily use recommended to monitor improvements over weeks

Is this formula gentle enough for sensitive or acne-prone skin?

The formula is fragrance-free and includes calming and skin-comforting ingredients such as beta-glucan, carnosine, and vitamin E. Clinical patch testing showed no irritation, and the product was evaluated as suitable for acne-prone complexions.

• Fragrance-free to reduce irritation risk
• Beta-glucan and carnosine help soothe and support the skin barrier
• Tested compatible with sensitive and acne-prone skin
• Non-greasy, easily layered texture for daily use

Who this is for: LAYERLAB Dark Spot Serum is designed for anyone wanting to reduce the visible appearance of lingering post-blemish marks, yellowish dullness, or uneven-looking skin tone without adding heavy textures or fragrance. It suits people seeking a clinical-style, daily tone-care step that pairs well with moisturizers and sunscreen—especially those with sensitive or acne-prone skin who still want targeted brightening benefits.
