What does Kojic Acid do?
Kojic Acid helps reduce the appearance of dark spots, melasma, sun damage and post-acne pigmentation by helping to limit excess melanin production.

Can I use this serum every day?
Yes. Most skin types can use it daily. If you have sensitive skin, introduce it gradually and increase frequency as tolerated.

Can I use this with Vitamin C?
Yes. Many people successfully use Vitamin C in the morning and Kojic Acid in the evening. If using together in the same routine, introduce products gradually.

Can I use this with Retinol?
Yes, although if your skin is sensitive it is often best to alternate evenings to minimise irritation.

How long before I see results?
Many users notice brighter-looking skin within a few weeks, while more stubborn pigmentation may require consistent use for 8–12 weeks alongside daily sunscreen.

Is this suitable for sensitive skin?
The formula contains soothing and hydrating ingredients to support the skin barrier. However, patch testing before first use is always recommended.
