What exfoliant would you suggest I use if I’m using Retin A? And do I put the exfoliant on before or after the Retin A?

Thank you for your question. Both exfoliants and Retin-A aid in the cell turn over, therefore these can be too irritating if used combined. I would recommend to use Retin-A once a week and the exfoliant 2-3  times a week and allow the skin to rest in between. Remember to moisturize heavily to replenish and maintain the barrier of the skin. Also, avoid over exposure to sunlight after using these product as the skin can become sun sensitive immediately after, so use sunscreen daily. 
I hope this helps.

Hello and thank you for your question. Retin-A has exfoliating effects on skin, so I would caution against using additional exfoliant as your skin may experience too much irritation. I would recommend a consultation by a board certified dermatologist for evaluation of your skin and discussion of appropriate treatment. Best of luck.
