Is tanning healthier?

No, tanning is a protective reaction of the skin. When thermal radiation or sunlight irradiates the skin, it stimulates and activates melanocytes located in the basal layer. Melanocytes contain melanosome, which can transfer melanosome to keratinocytes. The more melanosome is produced and transferred, the darker the skin color. Of course, the other two components of skin color are blood oxygen content and stratum corneum thickness. With the decrease of oxygen content, the thicker the stratum corneum, the darker the skin color.

Skin care should master three principles:

First, cleaning should not be excessive, and frequent exfoliation or scrubbing is not allowed, especially on the face. Oily skin can be used once a month, and dry and sensitive skin can be exfoliated.

Second, don't change the brand of skin care products frequently. The main purpose of skin care products is to prevent water from evaporating through the skin and balance the oil-water ratio. Other effects are not as good as drugs. If you want to find the effect of improving wrinkles and spots from skin care products, it is better to ask a doctor and use some efficient, safe and cheap drugs. So you can use a cosmetic brand for life.

Third, we must pay attention to sun protection. Skin aging can be divided into natural aging and photoaging, and sun protection can delay photoaging, thus delaying skin aging. Physical sun protection is as important as chemical sun protection. Children within 6 months are mainly protected by physical shielding. The stronger the light, the stronger the sun protection ability of the product, and the greater the role of light indoors, so it is necessary to protect the sun indoors.
