I agree with the other poster, go slow and gentle. Cleanser, moisturizer, sunscreen. If you start wearing sunscreen daily at your age, your skin will be beautiful even at my age (an ancient 42 😀) I wish I could go back in time and tell my young self to wear sunscreen and stay out of tanning booths!
Here are the products I would highly recommend. I have very sensitive skin and these never caused me any problems plus they work well and are cheap.
Cleanser Hada Labo Gokujyun foaming cleanser
Super mild, not drying, a great cleanser.
Moisturizer Bonajour Green Tea water bomb moisturizer
Light, hydrating, spreads easily and doesn't leave you shiny
Sunscreen Nivea Super Sun Water Gel
Dries super quick and doesn't feel like you are wearing sunscreen. Love it!
In the morning you probably can get away with just water to wash your face. Then moisturizer and sunscreen. In the evening, wash with the cleanser, then moisturizer.
After you get this simple routine down have fun with sheet masks! Put them on after you wash your face before moisturizer. What kind of mask really doesn't matter, masks don't do much other than hydrate, so get cheap ones and have a spa night!
