At 20, the goal is generally not to treat wrinkles, but to preserve the skin and prevent future damage.
Regarding the tip (tomato + sugar):
Tomatoes may contain antioxidants, but their effect on wrinkles is limited.
Sugar acts as a mechanical scrub and can irritate the skin, especially if it is sensitive or acne-prone.

Morning
Gentle cleanser.
Moisturizer suited to your skin type.
SPF 30 to 50 sunscreen daily (the most important for preventing skin aging).
Evening
Gentle cleanser.
Moisturizer.
Optional: a niacinamide serum if you have visible pores, redness, or blemishes.
Depending on your skin type:
Oily/acne-prone skin: niacinamide or salicylic acid.
Dry skin:
