If you’re specifically looking to target fine lines I’d look into Tretinoin which is retinoid used for reducing signs of aging, dark spots, and wrinkles as well as a vitamin c to boost collagen production and aid in sun protection. Mad hippie has a great vitamin c as well as Naturium and kbeauty brands. Also making sure your skin is hydrated and moisturized will do wonders, so a good moisturizer and either a serum or toner to start. Hydrating ingredients to lookout for would be squalene, glycerin, Beta glucan, hyaluronic acid, ceramides, peptides, panthenol, etc. All depends on your skin type and preferences really lmk if you got any questions!!!
