Reversing ageing skin involves a combination of treatments and lifestyle changes. Topical retinoids, antioxidants like Vitamin C, and peptides can help rejuvenate the skin by promoting collagen production and improving skin texture. Professional treatments such as laser resurfacing, chemical peels, and microneedling can also stimulate skin renewal. Additionally, maintaining a healthy diet, protecting the skin from UV exposure with sunscreen, and staying hydrated are crucial for maintaining youthful skin.
