UV radiation accelerates the breakdown of collagen and elastin in the skin leading to the formation of wrinkles. Skin aging, hyperpigmentation, and skin cancer are common causes of sun damage. Sun damage can cause the skin to become rough and uneven and chronic sun exposure can lead to thickened, leathery skin. To reduce the sun damage retinoids, vitamine C and niacinamide are common ingredients. Professional treatments are chemical peels, laser therapy and microneedling.
