Visibly fade dark spots, hyperpigmentation and post-acne marks with our precision-formula serum built around the maximum EU-allowed concentration of Kojic Acid — 1%.

Unlike broad brightening moisturisers, this serum is designed to target. Apply it directly where you see uneven tone, sun-related discolouration or post-acne marks. The 1% Kojic Acid works by moderating melanin synthesis in the skin, so existing dark spots look progressively fainter and new discolouration is less likely to become visible.

Why Kojic Acid at 1%?

The EU and UK cap Kojic Acid at 1% in leave-on products — not because it's weak, but because at this concentration it's both safe for daily use and clinically effective. Positine formulates to this standard so you get results without compromise.

What you'll notice

• Fewer and fainter dark spots within 4–6 weeks
• More even skin tone overall
• Brighter, more uniform complexion
• Lightweight texture — absorbs fast, layers under SPF or moisturiser

How to use

Apply a small amount to cleansed skin, concentrating on areas with dark spots or uneven tone. Use morning and/or evening. Follow with SPF during the day — Kojic Acid increases photosensitivity, so sun protection is non-negotiable.

A note on diagnosed pigmentation conditions

Patchy pigmentation has many causes, and some of them — such as melasma or post-inflammatory marks — are best assessed by a professional. This is a cosmetic serum formulated to support the look of a more even tone; it is not a treatment for a diagnosed skin condition. If you are managing one, or you are pregnant or breastfeeding, speak to a dermatologist or pharmacist before adding a new active to your routine.
