Frequently Asked Questions
Which skincare step is the most critical investment for anti-aging?
Broad-spectrum SPF 30+ sunscreen and nighttime Vitamin A (Retinol or prescription Tretinoin) are clinically proven to have the highest ROI, preventing up to 80% of visible UV photo-aging and stimulating cellular turnover.
Why do opened Vitamin C serums need to be replaced every 2 to 3 months?
L-ascorbic acid (pure Vitamin C) oxidizes rapidly upon exposure to light and ambient air. Once the clear or pale serum turns dark amber/brown, it has oxidized into dehydroascorbic acid and can actually promote free radical formation.
