Skin care, skin problems...

[Kaemythra]

I was thinking of reducing my use of skincare products, I've always done a lot of skincare for years, but nowadays I realize that the products I buy no longer have a good effect and only make my face worse, I'd like to go for more natural and basic products.
That could prevent expression lines, acne and spots on my face. I still only know the basics and I'm still researching, so I'm asking for help if anyone has any more tips or recommendations.
My routine is basic, but it seems like even the basics don't work anymore. Cleansing, moisturizing, and sunscreen. At night, I just cleanse, moisturize, and use retinol (0.15%).
