5 experts · Moderate agreementWhat the gurus are saying
The azelaic acid derivative potassium azeloyl diglycinate is the ingredient reviewers keep singling out. Most found it hydrating, gentle, and helpful for breakouts and shine, with the strongest praise from those with oily or acne-prone skin. Not everyone agreed, and the less impressed camp says it does little for congestion and that better options exist at this price. Since the texture reads as thick, a small amount goes a long way.
