Alpha Arbutin vs Vitamin C
Which is right for your skin?
Alpha arbutin is a targeted, low-irritation spot-fader; vitamin C brightens overall tone and adds antioxidant defense. Arbutin for stubborn spots, vitamin C for all-around glow — they layer well.
A safer, slower-acting alternative to prescription-strength dark-spot faders. Built for long-term use without irritation.
Brightens dull skin and helps fade dark spots. Also defends against everyday UV and pollution damage when worn under sunscreen.
Can you use Alpha Arbutin and Vitamin C together?
