Active C Ampoule FAQs

FAQs

What makes Active C Ampoule different from other Vitamin C serums?
Active C Ampoule is designed as a skin-strengthening system, not just a brightening serum. It combines 25% stabilized Vitamin C with Triple Collagen and Centella EV™ to visibly brighten and firm while supporting the skin barrier for comfort.
Is 25% Vitamin C safe for sensitive skin?
The formula is designed to balance high performance with comfort. Centella EV™ and Madecassoside help calm and support the skin barrier. If you have very sensitive skin, we recommend starting every other day and increasing as tolerated.
When will I see results?
Many users notice a brighter, smoother-looking complexion within 7–14 days of consistent use. Results may vary depending on individual skin condition and routine.
Can I use Active C Ampoule every day?
Yes. Active C Ampoule is suitable for daily AM and PM use. Always apply sunscreen during the day when using Vitamin C products.
Can I layer this with other skincare products?
Yes. This ampoule layers well with hydrating and barrier-supporting products. If using exfoliating acids or retinoids, we recommend alternating usage or applying them at a different time of day.
What is the size of the bottle?
Each bottle contains 1.2 fl oz (35 mL), which is approximately 17% more than standard 30 mL Vitamin C serums.
Is Active C Ampoule fragrance-free?
Yes. Active C Ampoule is fragrance-free and formulated to be comfortable for sensitive skin types.
