I just wanted to get some opinions on this.. I am trying to even out my skin tone with the usual (retin-A .1% & HQ 4%). I know it is said that you should wear sunscreen always and a hat, etc. I personally don't mind getting tan although it is my life's mission now to protect my skin and wear sunscreen, BUT I don't want any hyperpigmentation either from the products I'm using. So the question is, about how long after you stop using retin-A and HQ is it okay to go back in the sun without any side effects??
