Does Salicylic Acid Cause Purging? Dermatologist Q&A

Dermatologist Dr. Dray answers more skincare questions from viewers, covering colloidal oatmeal, retinoid purging, glycolic acid, salicylic acid cleansers, minoxidil, veinous lakes, and skin tightening after weight loss. In this skincare Q&A, Dr. Dray explains the difference between colloidal oatmeal and Avena Sativa (oat) meal extract, whether switching from tazarotene to tretinoin can cause breakouts, and what determines how strongly a 10% glycolic acid body product exfoliates. She also discusses treatment options for mild loose or lax skin after significant weight loss, whether veinous lakes on the lips are related to sun exposure, and why salicylic acid cleansers can still exfoliate the skin even though they are rinsed off. Several questions address the relationship between salicylic acid and minoxidil, including an important distinction between salicylic acid and aspirin. Dr. Dray also explains why "purging" is often incorrectly blamed for breakouts and irritation from skincare products.
