Collagen is the body’s key structural protein responsible for skin firmness, elasticity, and a youthful appearance. As we age, natural collagen production declines, leading to wrinkles and loss of firmness. While diet, supplements, and skincare products like retinoids and vitamin C can support collagen health, the most effective approach combines sun protection, nutrient-rich foods, and consistent skincare habits to preserve and stimulate collagen over time.
