Detailed answer

Allergies to skincare products can cause various reactions on the skin, such as redness, itching, rashes, or inflammation. However, sagging skin is primarily caused by natural aging, loss of collagen and elastin, sun damage, genetics, and lifestyle factors like smoking or excessive weight loss. Allergies typically do not affect the structural integrity of the skin or its elasticity. It is important to identify and avoid skincare products that trigger allergic reactions to maintain healthy skin. To prevent sagging skin, it is advised to protect your skin from the sun, maintain a healthy lifestyle, eat a balanced diet, and use skincare products with ingredients known to promote collagen production and skin elasticity.
