What it is
- A topical cosmetic/dermal product containing 1.5% kojic acid as the primary active ingredient aimed at reducing hyperpigmentation and evening skin tone.
Main uses
- Lightening of dark spots, post‑inflammatory hyperpigmentation, sun spots, age spots, and mild melasma.
- Brightening overall complexion and improving skin tone.
How it works
- Kojic acid inhibits tyrosinase, an enzyme needed for melanin production, which can reduce pigmentation over time.
How to use
- Cleanse and dry face. Apply a thin layer to affected areas once daily to twice daily as tolerated (follow product directions).
- Start with once daily and increase only if no irritation occurs.
- Perform a patch test on a small skin area for 48 hours before regular use.
Precautions & side effects
- Can cause irritation, redness, itching, stinging, or contact dermatitis—more likely if skin is sensitive or product is overused.
- Avoid eyes, lips, mucous membranes, and broken skin.
- Use daily broad‑spectrum sunscreen (SPF 30+) and limit sun exposure while using kojic acid—photosensitivity and reduced efficacy without sun protection.
- Stop use if severe irritation or allergic reaction occurs.
- If pregnant or breastfeeding, consult a healthcare provider before use.
Complementary ingredients & combinations
- Often paired safely with moisturizers, niacinamide, and low‑strength AHAs/BHAs if tolerated. Use caution combining with other strong actives (retinoids, high‑strength AHA/BHA, vitamin C) to avoid irritation—introduce gradually.
Storage
- Keep in a cool, dark place; tightly capped. Discard if color/odor changes.
