Personally, you got nothing to lose. Make sure to do research and start at a low dose. Many people find that their skin is getting worse and they get results after 5 months or so, so it really depends if you wanna go through that. If you start now, im sure ur future self would be thanful. If you do, make sure to wear sunscreen as ur skin will be much more sensitive.
The bare minimum skincare i think anyone should have is a cleanser ,moisturizer and sunscreen.
