Detailed answer

Intrinsic aging is the result of internal factors such as genetics and the natural decline in hormone production. It involves the progressive loss of collagen and elastin in the skin, leading to wrinkles, sagging, and thinning. Extrinsic aging, on the other hand, is primarily caused by external factors like sun exposure, smoking, pollution, and poor lifestyle choices. These factors accelerate the aging process by damaging the skin's structure and function, resulting in premature wrinkles, age spots, and uneven skin tone. While intrinsic aging is inevitable and cannot be completely prevented, extrinsic aging can be minimized by adopting a healthy lifestyle, using sunscreen, avoiding smoking, and practicing a consistent skincare routine.
