Ingredient Breakdown
Our editors analyze every active ingredient against published clinical literature. Here's what's actually doing the work in this formula:
Vitamin C (L-Ascorbic Acid)
The most potent and best-studied form of topical Vitamin C. Directly stimulates collagen synthesis and provides antioxidant protection against UV and pollution-induced free radical damage.
Vitamin E
Synergistic antioxidant that stabilizes Vitamin C and doubles its efficacy in combination — the Vitamin C + E + ferulic acid trio is the most evidence-backed antioxidant combination in dermatology.
Hyaluronic Acid
Provides surface hydration and helps the skin feel comfortable during Vitamin C use, counteracting any potential dryness.
Who Should Use This?
✓ Perfect For
Anyone beginning their antioxidant skincare journey. Those who want Vitamin C's brightening and collagen benefits without paying premium serum prices.
✗ Skip If
Those with very sensitive or reactive skin (witch hazel can irritate); those who want the highest concentration Vitamin C with maximum efficacy (consider Skinceuticals CE Ferulic at higher price points).
How to Use It
Apply 3–5 drops to clean, dry skin every morning after cleansing. Allow 60 seconds before applying moisturizer. Follow with SPF 30+ — Vitamin C enhances sun protection when combined with sunscreen.
Frequently Asked Questions
Why does my Vitamin C serum turn orange?
Oxidation. L-Ascorbic acid oxidizes when exposed to light, heat, and air, turning from clear/pale yellow to orange/brown. An orange serum has lost most of its efficacy. Store in a cool, dark place, keep the cap tight, and replace every 3 months after opening.
Can I use Vitamin C with retinol?
Yes, but not at the same time. Use Vitamin C in the morning (antioxidant protection during the day) and retinol in the evening. Both are less stable and more degraded in combination and with UV exposure.
