I was just talking with some girlfriends tonight at Reagan’s dance rehearsal and they asked me about this too! This retinoid is marketed as acne treatment (all retinoids work for acne) but this is the strongest retinoid available OTC. Yes it helps with acne, but it also helps with hyperpigmentation, wrinkles, fine lines, improved skin texture etc. So all the expensive ones that advertise strictly as being for anti aging that you also buy OTC are weaker than this one. It’s just marketing 😉
