Frequently Asked Questions
Is 20% Niacinamide too much for skin?
High concentrations require a patch test to verify tolerance. It treats stubborn texture but may cause redness on sensitive skin.
Can I use Cos De BAHA NZ serum every day?
Daily application works for oil-heavy skin once acclimated. Start with every other day to prevent drying out the skin.
