Skin Treatments

[ExplorePS]

Hello PSers! I'm struggling with adult acne as I've mentioned in another thread but I'm realizing that once I get rid of this problem, I want to start making my skin a priority and not take it for granted. My husband recently went to the dermatologist to make sure his darkened spots weren't cancerous. The dermatologist recommended him visit the affiliated esthetician. Instead of the initial suggestion of some sort of laser treatment, she did a chemical peel instead on his face. Wow, I couldn't believe it that 1 treatment showed so much benefit. Though it will take him a total of 3 to get rid of all the darkened areas. So it got me thinking and appreciate if you had any experiences to share:

Question 1 - Is a dermatologist affiliated esthetician any different from going to a spa and doing their treatments? Or rather is a chemical peel the same no matter what place you go to? He was charged $300 for the visit but I see other places charging closer to $100.

Question 2 - What other skin treatments would you recommend that is effective, longer lasting that isn't invasive like botox? I'm wondering if after I get the acne cleared up, is it good practice to do 1 chemical peel a year? I've never left a facial thinking "wow I look significantly different" but would like to do some prevention as I'm approaching my 40s.

Thanks in advance!
