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 damage, melasma or post-acne marks. The 1% Kojic Acid works by interrupting melanin overproduction at the source, so existing dark spots fade and new ones are prevented.

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

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.
