Detailed answer

Collagen, a protein found in the skin, provides structural support and elasticity. As we age, the production of collagen decreases, leading to a loss of firmness and sagging. Without enough collagen, the skin becomes less able to bounce back and maintain its tautness. External factors like sun exposure, smoking, and poor diet also contribute to collagen breakdown, exacerbating sagging skin. To combat this, it is important to incorporate collagen-boosting ingredients and treatments, such as topical retinoids, peptides, and professional procedures like laser therapy or microneedling, into skincare routines.
