| ㆍNOTICE - 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. |
| ㆍCAUTIONS - 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. |
| ㆍFAQ |
|---|
|
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. |
