Using a retinol serum on blemish-prone skin can be a tricky balance—while they're meant to target breakouts and boost cell turnover, they can also trigger irritation, dryness, or purging before improvements are apparent—and Sunday Riley's AI Smart Retinoid Serum was created to "[redefine] what retinol serums can do for blemish-prone skin."

This gentle dual-action formula pairs advanced retinoids, Hydroxypinacolone Retinoate (HPR) and Adapinoid, to address visible congestion, texture and pore size, and at the same time, diminish the appearance of redness. This smart formula pairs advanced retinoids with time-tested adaptogenic herbs like astragalus and holy basil, plus a peptide complex.

Previously, Sunday Riley introduced a high-dose retinoid serum called A+, and AI is a new smart serum that specifically supports blemish-prone skin.
