NOTICE
Storage & Stability Guide
Store in a cool, dark place away from direct heat and sunlight. Refrigeration after opening is highly recommended to maintain peak freshness. Pure L-Ascorbic Acid (Vitamin C) may naturally turn light yellow over time due to exposure to air and light. This is a natural characteristic of pure Vitamin C and is safe to use.
CAUTIONS
Cautions & Sun Protection
For external use only. Avoid direct contact with eyes and broken skin. A mild tingling sensation may occur initially due to the high concentration of pure Vitamin C (15%). Always follow with a broad-spectrum sunscreen during the day. Discontinue use if persistent irritation occurs. Keep out of reach of children.
FAQ
Q1. Does it need to be refrigerated?
A. Refrigeration is not strictly mandatory if stored in a cool, dark place, but keeping it refrigerated after opening helps extend product stability and potency.
Q2. Can I use it alongside AHA, BHA, or Retinol?
A. We recommend using pure Vitamin C in your AM routine and Retinol or exfoliating acids (AHA/BHA) in your PM routine to avoid skin irritation.
Q3. Is a slight color change normal?
A. Yes, pure Ascorbic Acid fine powder naturally oxidizes into a pale yellow tint over time. It remains effective and safe for use unless it turns dark brown.
