If you have sensitive skin or conditions such as eczema or rosacea, it may be best to avoid using glycolic acid, as it can be too harsh and potentially cause irritation. It's always a good idea to consult with a dermatologist or skincare professional to determine if glycolic acid is suitable for your skin. **
