Age spots, also known as liver spots or solar lentigines, are pigmented patches that commonly appear on the skin as people age. While they are often associated with external factors like sun exposure, their underlying cause extends beyond the surface. Here's a deeper look at what age spots are and what they signify:

1. Lipofuscin Accumulation: Age spots are a visible manifestation of lipofuscin accumulation in skin cells. Lipofuscin is a yellowish-brown pigment that forms as a result of cellular waste buildup and oxidative stress. It is often referred to as the "wear-and-tear" pigment, as its presence indicates cellular damage and aging.

2. Free Radical Damage: The formation of lipofuscin is closely linked to free radical damage within skin cells. Free radicals, unstable molecules generated by various internal and external factors such as UV radiation, pollution, and stress, react with cellular components and contribute to oxidative stress.

3. Sign of Cellular Waste Accumulation: Age spots serve as a visual indicator of cellular waste accumulation and free radical intoxication within the body. The presence of these spots suggests that cells are burdened with accumulated waste products, compromising their function and contributing to skin aging.

While age spots may be a natural consequence of aging and environmental exposures, adopting lifestyle habits that promote antioxidant protection and cellular detoxification can help mitigate their formation and support overall skin health.
