Known Interactions
Combining retinol and salicylic acid (BHA) in the same routine can lead to over-exfoliation, especially for sensitive or dry skin types. Salicylic acid's low pH may also reduce retinol's effectiveness. The combination is more tolerable than retinol + AHA but still warrants caution.
Recommendation: Alternate use: apply salicylic acid in the AM (if needed) and retinol PM, or use on different nights. If your skin is not sensitive, some users tolerate layering with a buffer moisturizer in between. Monitor for irritation.
