Answer

Ascorbyl Glucoside vs L-Ascorbic Acid: Skin Dryness

Ascorbyl Glucoside is generally considered less likely to cause skin dryness or irritation compared to L-ascorbic acid.

Here's why:

  • L-Ascorbic Acid: This form of Vitamin C is highly effective but requires a low pH (typically 2.0-4.0) to remain stable and penetrate the skin effectively. This acidic environment can sometimes lead to dryness, stinging, or irritation, especially for sensitive skin.
  • Ascorbyl Glucoside: This is a stabilized derivative of Vitamin C. While it is converted into L-ascorbic acid in the skin, it is stable at a higher, less acidic pH range (6.5-6.8). This higher pH makes formulations containing Ascorbyl Glucoside generally milder and less irritating, thus less likely to cause dryness compared to formulations with L-ascorbic acid at its optimal low pH.

Both forms offer benefits like skin brightening, antioxidant protection, and collagen stimulation, but Ascorbyl Glucoside provides a gentler option for those concerned about potential dryness or sensitivity from L-ascorbic acid.
