Thank you Mabrook and Roxx 
for both of ya 
OK, so I decided against Retin-A for the reason you guys mentioned that it’s quite potent. So, retinol is the way to go? I looked up DHC website and the product looks quite good to me.
Have you guys ever used Skinceuticals Retinol? I read many very positive reviews for the product on makeupalley.com. But it’s really pricey. A little bottle comes for $56 US and they don’t ship to Canada 
So the question now is whether should I go for generic retinol cream/gel or some high-end brand one?
