Y'all, wearing sunscreen every day (even when it rains!) is the Number One Way to prevent/delay wrinkles, dark spots, and so many other signs of aging. And the sooner you start, the better prevention you get. (FYI, it doesn't matter which sunscreen you use, as long as it's labeled "broad spectrum", is at least SPF 30, and you like it enough to actually wear it.) This particular product's a bit pricier than your typical drugstore brand, but reviewers say it's great for sensitive and acne-prone skin.
Promising review: "My dermatologist suggested this to me. I have tried tons of sunscreen... TONS, all price points and all brands. I prefer physical blockers but they never mesh with my makeup, make me so greasy (and I'm already oily/combo), or leave a ghostly white cast on my deep brown skin. This absorbs easily, has no strong fragrance, plays well with makeup and moisturizer, is still effective is Houston summer heat and humidity, and doesn't trigger my adult acne. I like that I can pump out a lot or a little bit. It is not clear — it does leave a slight white cast on my skin, however It does dissipate and I always use at least powder to make my skin more even and absorb oil." —AseaNoe
