CE Ferulic Formula: Skin Thinning, Photosensitivity, and pH Level

Subject: CE Ferulic Formula and Skin Thinning

Regarding your questions about the CE Ferulic formula:

1. Does L-ascorbic acid make skin thin or photosensitive?
   Based on the information provided, the claim that L-ascorbic acid makes skin thin or photosensitive when used continuously is not true. While L-ascorbic acid is an acid, it is not an Alpha Hydroxy Acid (AHA) and does not cause significant skin exfoliation that would lead to thinning. The belief that it makes skin photosensitive appears to be a misconception.

2. What is the pH of the CE Ferulic formula?
   The pH of the CE Ferulic formula is in the range of 3.0-3.5.

The pH level alone does not cause excessive exfoliation or skin thinning. A pH of 3.5 is considered very safe for daily use in cosmetic products according to Thai FDA standards.
