Beauty Tips For Body Care
Current routine.​Here was my adult acne at it's worse! This is when I initially reached out to this community for help, and I was so fed up with how I looked that it threw me into a spiraling depression thinking I'd never look normal. Long story short, I read the side bar and decided to start hydrating my face and using Differin to actively treat the acne.​Side1 Side2. Here were both sides of my face after the acne itself started to subside a little bit and I was left with some scars.Here is what my face looks like now. 1 2​Obviously super happy from how it looked the year before, however I still have some Atrophic scarring and some PIH or PIE? (My scraggly facial hair is hiding some of it). All I know is that there are some dark spots where the acne assaulted the right side of my face (Picture 1 of most recent). To try and ameliorate the damage, I was using an AHA exfoliant Glycolic Acid (The Ordinary Glycolic Acid Toning Solution). Honestly, I haven't been real diligent with using the Toning solution because I haven't really seen any results from it yet.​My question is, what other treatment should I pursue to treat some of the Atrophic scarring and pigmentation from all the acne I had? What about another type of AHA? How long should I use The Ordinary Toning Solution for? It says on the bottle only use for a limited amount of time.​Thanks everyone for all the help you've provided me! Your advice have been invaluable.
