i am like the LAST person to go for like dieting tips or anything because my metabolism has always been very fast so i just ate junk a lot (i have high cholesterol now though so im trying to be better but i suck at it lol)
honestly try and exfoliate regularly not like everyday but maybe once a week and use a weak acid toner or maybe serum that has aha and bha in it and use a good moisturizer for your skin type
i recommend going on paulas choice website they explain it a lot better than me
for acne i use clean and clears persagel to spot treat but everyones skin reacts differently to things like this its benzoyl peroxide based and some people react really well to this or salicylic acid i try to take preventative measures with my skin so i have to worry about breakouts less
and if someone comments on your looks negatively fuck them!!! thats so rude
and don’t worry you’ll get through this and find that confident place again!
