What the gurus are saying

The experts who reviewed it found this retinol strikes a balance between strength and gentleness, with vitamin E built in to hydrate as it works. The 0.5% concentration is potent enough to deliver results, but that means those with sensitive skin may want to start slowly or consider stepping up from a lower-strength retinol first. One guru noted it's more forgiving than other 0.5% retinols on the market, making it a solid middle-ground option for anyone ready to move beyond beginner retinoids.

"COSRX Retinol 0.5 is a super vitamin E plus one. So it's moisturizing as it is a retinol. It's a great product. But that's retinol, so it's going to be a little bit more for not for sensitive skin. I don't want to say that because the new trend is not to thrash your skin like crazy. It's to use gentler products that are effective used consistently in a strategic way."

"It's strong but gentle. No D Ordinary 0.5% I would never recommend as your first retinol because it is a strong formula and it's scaling. It's like hydrating, oily types. The formula is strong, but this is on number four. It has 0.5% retinol. If you are size try something and Cosrx Retinol 0.5%, which is an red, it also has 0.5% concentration. It is really beautiful. That is 0.3 and then you go less concentration which has 0.2% retinol and one percent peptide. Again if you don't want to apply peptide separately, don't apply retinol separately, fabulous option, beginner friendly. And then you go the request cream which has 0.1% retinol. It is gentle with 0.5%."
