What are your favorite OTC products that contain retinAL (not retinOL)?
My current one, Noon Charisma 1% (middle strength), has been doing well for my skin, but it’s Retinol. Costs about $130 per bottle. I previously used for years a retrinAL product and liked it a lot, but I actually think the Noon has given me better visible results. I saw a video saying Retinol has to convert twice to be effective but retinal only converts once and that’s better. So now I think I may want to switch to a retinAL product that others have had great results with.
