It's always a good idea to consult with a dermatologist or skincare professional to determine if glycolic acid is suitable for your skin. **

Sulfuric acid is considered the strongest acid among the three mentioned - sulfuric acid, nitric acid, and hydrochloric acid. This is because sulfuric acid is a strong acid that is highly corrosive and can react vigorously with many substances. Nitric acid and hydrochloric acid are also strong acids, but sulfuric acid is generally considered to be the strongest due to its ability to fully dissociate in water and its powerful oxidizing properties. **
