I have been using Satin Naturel Organic 3% Retinol Serum for the past 2 years. The ingredients are lovely and it also contains argon oil and vitamin c so it feels lovely on my skin. Can't say I look any younger but thought I was doing my best. However, I just read an article that said you can't get 3% retinol over the counter in the UK, which made me suspicious. I went online to check over the ingredients of my serum and saw that it says "3% retinol delivery system". Now I'm pretty sure that sounds like a clever bit of waffle, and that's it's not actually 3% retinol after all?!!
Are there any retinol experts who can confirm?
Second question, what is the highest percentage retinol I can buy over the counter and what serums do you recommend? There are a great many vlogs and Top 10 lists online but they rarely mention the actual % strength of retinol / Vit A.
