Detailed answer

Collagen is a vital protein that plays a significant role in maintaining the structure and firmness of the skin. It provides support to the skin's tissues, helping to keep it elastic and supple. However, as we age, collagen production naturally decreases, and existing collagen structures break down more easily. This decline in collagen leads to a loss of skin elasticity, resulting in sagging skin. Additionally, external factors like sun exposure, smoking, and poor diet can further accelerate collagen breakdown. To address sagging skin, collagen-boosting treatments, such as topical creams containing retinol or peptides, and procedures like laser resurfacing or skin tightening treatments, may be beneficial.
