Achieving healthy skin requires a combination of nutrition, topical treatments, and lifestyle habits. Dietary support includes Vitamin C for collagen production, antioxidants like lycopene and ~~polyphenols to combat oxidative stress,~~ polyphenols, and healthy fats such as omega-3s to maintain the skin barrier. Recent research suggests that aging is heavily influenced by the interaction between genes and the environment, specifically through nutrition. To manage age-related reductions in collagen and elastin, dermatologists recommend daily sunscreen use and high-quality protein consumption. omega-3s. Experts emphasize that daily sun protection is the most critical step in preventing wrinkles, noting that ~~popular~~ products like retinol ~~and vitamin C~~ are less effective if UV damage is not addressed. Because UVA rays can penetrate clouds and glass, a broad-spectrum SPF of 30 or higher is recommended to prevent pigmentation and loss of elasticity. Dietary choices can further strengthen natural defenses. Beyond general nutrition, specific foods such as tomatoes (containing lycopene), carrots (providing beta-carotene), and leafy greens like spinach (offering lutein and zeaxanthin) are highlighted for their role in skin renewal and UV sensitivity reduction. As skin ages, particularly for those over 60, strategies should shift toward simplicity and repair using ingredients like ceramides and hyaluronic acid. Experts warn against overcomplicating routines, as adding too many active ingredients can stress the skin. Lifestyle management remains vital; habits such as smoking, excessive sun exposure, poor sleep, and unbalanced diets accelerate aging. Biologically, as natural peptide production declines, the targeted use of peptides may support firmness by stimulating collagen and elastin synthesis.

Because retinoids can be irritating, experts recommend a gradual reintroduction. If the skin is currently peeling or sensitive, the focus should remain on gentle cleansing, hydration, and consistent SPF application rather than immediate high-strength treatments. Additionally, the décolletage requires specific attention during this period, as it is frequently vulnerable to UV radiation, often resulting in uneven texture and fine lines by autumn.
