Hi. Thank you for your question. Sorry about the stinging. Find a deep moisturizer with a high content of hydrocortisone or use hydrocortisone in conjunction with the moisturizer. Rest assured that this stage will last for only a few more days. It sounds as if you may have sensitive skin so...
I would definitely be more careful in the future after a chemical peel since your skin is more sensitive and you are not supposed to be in the sun afterwards. I would consult your treating physician for assessment and guidance at this point and perhaps they will prescribe a burn cream for you ...
The neck and chest are very sensitive areas. It is not uncommon for them to become red and irrated with Retin A. I would encourage you to discuss your progress with your aesthetician to ensure this is the type of reaction she was hoping for with your treatment.
