Best skincare tips

I used to have amazing skin but last year it got really bad. I took hydra facials etc but nothing seemed to help.

I still look at my face and think it’s full of pimples but upon touching it i found out that they’re just spots. No bumps just spots.

Also i went on a trip recently and got REALLY tanned.

Pls give your best tips to deal with both these issues. (I try to stay away from chemicals after my breakout last year. Currently i use only niacinamide- minimalist)

Bonus- haircare tips are also most welcome- i have thin straight-wavy hair. Oily scalp dry roots. Loads of frizz. (Dont suggest products for hair pls, need home remedies)
