Can I use Tretinoin with AHAs (glycolic and lactic acid)?

Yes, you can use Tretinoin with AHA's.  Always start slow when beginning a Tretinoin product.  Start 2 times a week for 2-3 weeks then 3 times a week for 3-4 weeks and add on nights as your skin acclimates to the product.

You can use both as long as your skin can tolerate both products together. If you use the glycolic and lactic acid every night then add the tretnoin once a week until your skin gets acclimated. Tretnoin is supposed to be used only at night and remember to use a good physical sunblock. 

Yes - that is a great idea. Start slow, then accelerate treatment. 3-4 nights a week, then increase as tolerated. You can also do high strength retinoic acid peels spaced 2-4 weeks apart. More on this in my recent videos on YouTube ( how to use vitamin A) regards, Dr Davin Lim. Brisbane. Australia.
