Adapalene (Differin) and Ketamine Therapy | Tovani Health
Differin (OTC since 2016) (Adapalene) (also: Epiduo (with benzoyl peroxide)) — Third-generation topical retinoid (acne; OTC)
Verdict at Tovani Health
Fully compatible — newer retinoid with milder irritation than tretinoin.
Topical adapalene and ketamine have no clinically significant interaction. OTC since 2016 (was prescription Differin), now widely available. Similar mechanism to tretinoin but with milder irritation profile and better photostability. The intrinsic considerations are the same retinoid-class issues — initial irritation, photosensitivity, pregnancy contraindication. Combination with benzoyl peroxide (Epiduo) is common.
