"Lip lines" can be treated with topical retinoids, hydrating lip products with SPF, and in-office procedures like laser resurfacing or fillers to smooth vertical lines.
While no food replaces sunscreen, some can offer an internal layer of protection. Foods high in lycopene (tomatoes, watermelon) and flavonoids (dark chocolate, citrus) have been shown to provide a small degree of photoprotection.
Peptides are highly recommended. These amino acids act as messengers, signaling your skin to produce more collagen, which is essential for firmness and smoothing existing lines.
Foods rich in phytoestrogens (so, flaxseeds), antioxidants (berries, greens), and healthy fats (avocado, salmon) support hormone balance and combat inflammation, helping to maintain skin elasticity.
