What are sun spots and freckles?

What is the difference between sun spots and freckles? According to experts, sun spots and freckles are two completely different types of spots. Although they will become more serious due to strong ultraviolet rays.

1. Different causes of formation: The causes of freckles include: sun exposure can cause freckles, endocrine disorders can also cause freckles, freckles are caused by genetic genes, freckles are caused by cosmetics, and freckles are caused by nutritional deficiencies. The causes of sun spots are: ultraviolet rays, toxin accumulation, and cell stimulation.

2. Different shapes: Yellow-brown dot-like pigmentation spots on the facial skin. The lesions are light brown or dark brown, ranging in size from a needle tip to a mung bean, and are round, oval or irregular. Distributed in scattered or clustered forms, isolated and unintegrated. No subjective symptoms. The rash becomes darker and more numerous after sun exposure in the summer, while it becomes lighter or disappears in the winter. Sunburn spots can appear in different colors, including light red, red or even dark red, depending on each person's skin type and the damage to the skin caused by the sun. There may be slight bumps, which are initially oval in shape, but after a few days turn into scattered brown patches. Sunburn doesn't just appear on the face; it can also occur on the exposed skin on the arms, thighs, and back.

Sun spots start out as slightly raised, oval-shaped patches that turn into small, brown patches over a few days. In addition, sun spots do not only appear on the face, but may appear on other parts of the body, including the back, arms, and thighs.

Melasma is different. It is a skin disease common in middle-aged women. It often appears on the face, cheekbones, forehead and surrounding areas. Melasma is a butterfly-shaped symmetrical spot, also known as "butterfly spot"

Sun spots start out as small red dots. Later, depending on skin texture or skin damage from the sun, the spots may take on different colors, such as bright red, red, or even dark red.

At first, melasma looks like dirt, but over time it changes color to light gray or dark brown. They are large and small, with clearly visible edges, a smooth surface, and no pain or itching.

After understanding the difference between sun spots and freckles, I hope everyone can correctly distinguish them when treating the two. In addition, patients with sun spots must pay attention to their own skin care and take good sun protection when going out. Because it is far from enough to rely on treatment to remove sun spots. You need to develop good living habits to completely cure sun spots.
