Your Results Timeline

What to expect with daily Vitamin C use.

Week 1–2
Instant Glow Boost
Skin looks more luminous almost immediately. L-Ascorbic Acid begins neutralizing free radicals and brightening dull complexion from the first application.
Week 3–4
Dark Spots Start Fading
Hyperpigmentation and sun spots begin to lighten as Vitamin C inhibits excess melanin production. Skin tone becomes more even and uniform.
Week 5–6
Collagen Boost
Vitamin C stimulates collagen synthesis. Skin starts to feel firmer and more elastic. Fine lines around the eyes and mouth become less visible.
Week 8+
Radiant Transformation
Complexion is visibly brighter, dark spots significantly faded, and skin is protected against daily environmental damage. Best results build over continued use.

Frequently Asked

Why does this have 3 forms of Vitamin C?
Each form works at different depths. L-Ascorbic is most potent; Glyceryl Ascorbate and Magnesium Ascorbyl Phosphate provide sustained, deeper delivery.
Should I use this morning or night?
Morning is ideal. Vitamin C helps protect skin's appearance from everyday environmental stressors. Always follow with sunscreen.
Will this oxidize quickly?
Our formula includes Ferulic Acid which stabilizes Vitamin C. Store in a cool, dry place away from direct sunlight.
Can I use this with retinol?
Yes! Use Vitamin C in the morning and retinol at night. This is the gold standard routine recommended by dermatologists.
