How long does it take to get tanned in the hot sun? How long does it take to get whiter after tanning?

In recent days, the continuous high temperature all over the country is unbearable. It can be described as roasting. If we can go out to eat together at noon, it can definitely be regarded as an iron friendship! Many friends worry that such strong ultraviolet rays can quickly tan people? Today we will talk about this:

In fact, to explain this problem, mainly from two aspects, the first is the strength of ultraviolet rays, followed by the individual's physique.

Let’s talk about the strength of ultraviolet rays first. In fact, we will have some concepts about this. For example, the ultraviolet rays in summer are the strongest and the weakest in winter. In a summer day, the ultraviolet rays at noon are the strongest and the weakest in the morning and evening. .

Besides, personal physique, in life, you can indeed encounter some people who don't seem to get tanned very much, just like some people blush when they drink, and some people don't. Don't think it's caused by some powerful gene. In fact, people who are not easy to tan are more likely to be injured by UV exposure, that is, sunburn! Here we can simply understand that tanning is the melanin secreted by the body's skin as a form of self-protection, while sunburn is an acute inflammatory reaction of normal skin after exposure to the sun, manifesting as erythema, edema, blisters and pigmentation , desquamation.

Based on the above explanations, we can know how long it takes to get tanned, depending on the strength of the ultraviolet rays and the reasons for their own constitution. It may be an hour, or it may be longer, but I really don't want everyone to try it.

Generally speaking, the metabolic cycle of the skin is 28 days. We can simply understand that it takes 28 days to have a new "face". But don't be too happy, this is ideal, if you are exposed to UV again during the period, you will receive a discount for this process. (You can’t go out without going out for 28 days, there are also ultraviolet rays in the house)

In fact, after sunburn or tanning, you can do some more practical actions, such as towel ice compress to cool the skin, and go out to do sunscreen work, such as sunscreen, sun hat, sunglasses, etc. Anyway, be patient, your fair skin will come back soon.
