Age spots are often called “Age Spots” or “Liver Spots.” In some cases

They may be called “Solar Lentigo” or “Senile Lentigo.” The English word “spots” is use to describe dark brown or black spots found on the skin of older people. They often found on skin surfaces. That have exposed to sunlight for a long time. They can occur at any age, but are more common in the elderly. 

Age spots and freckles are not serious and do not cause pain, but they are often a concern for the elderly due to changes in skin health. These spots occur due to changes in the production and distribution of melanin in the skin. Age spots are different from common freckles in that the number of freckles increases with age and they do not usually fade away. Age spots cause the skin to become darker and often found in areas. That frequently exposed to the sun.

Factors affecting skin changes in the elderly

1. Intrinsic factors are the deterioration of cells over time. As we age, the ability of cells to function decreases. Cells divide more slowly. Cell repair to create new cells decreases. In addition, free radicals cause the accumulation of waste สมัครสมาชิก UFABET วันนี้ รับเครดิตฟรีทุกวัน products and increase the mechanism of cell destruction.
2. Extrinsic factors are the result of the environment, such as sun exposure, pollution in sunlight, consisting of UVA and UVB, which have the effect of damaging the DNA of skin cells, resulting in cell destruction, along with the creation of more free radicals, resulting in cell deterioration.

Behaviors that may cause freckles in the elderly

• Long-term exposure to the sun without applying sunscreen or wearing protective clothing or using sunscreen increases the risk of sunburn, dark skin, and freckles. Long-term exposure to the sun may increase the risk of freckles or an increase in the intensity of freckles on the skin. Sunlight contains ultraviolet (UV) radiation. There are three types of ultraviolet radiation: UVA, UVB, and UVC. All three types can cause collagen in the skin to deteriorate. 
• UVA can penetrate the deepest layer of the skin and is absorb more than UVB rays. Although UVA is the least severe, it can cause skin cancer. Our body can prevent this by creating melanin to prevent UV penetration. If this melanin pigment accumulates for a long time, it will become an accelerator that causes skin deterioration, premature aging, wrinkles, and sagging. And this melanin pigment is the cause of our skin color changing into freckles and melasma.
• • UVB rays are most intense between 10:00 a.m. and 4:00 p.m. They have higher energy than UVA rays and can cause sunburn, which we have seen or experienced when exposed to sunlight for long periods of time, especially when traveling to the beach or mountains in the summer or going skiing in the winter. The skin is expose to the sun until it turns red. This is because our skin is temporarily inflam. Which is also the cause of freckles and melasma. 
  • For UVC rays, they are no less harmful than UVA and UVB rays, but the Earth’s atmosphere can filter these rays, so they don’t affect us as much.
