 Can sugar pills protect against sun? Dont be lazy. Its better to use a sunshade!


This so-called sunscreen candy doesnt have the effect of sunscreen. After consulting the ingredients recommended by the artist, Li Kai, chief dermatologist of China Japan Friendship Hospital, told SciTech daily.

The ingredients of the sunscreen sugar include amylopectin, gardenia extract, glycerin, crystalline cellulose, modified starch, etc. its main ingredient is saffron acid in Gardenia, which is said to have strong antioxidant capacity.

Li also said that although saffron acid has anti-oxidation effect, for oral products, whether the anti-oxidation ingredients can be absorbed by skin tissue, how much they are absorbed, and how long they can be maintained after absorption before they are metabolized, all these problems need further verification.

The reporter of science and Technology Daily also inquired about several other oral products under the banner of sunscreen on an e-commerce platform. The slogan of one rejuvenated young girls muscle and effective anti ultraviolet for 12 hours was very exciting. Most of the ingredients in these products include plant ingredients, such as yam, lily, red orange extract, etc., and other substances such as vitamin C, maltodextrin, citric acid, etc.

In the same way, vitamin C, citric acid and other substances also have certain antioxidant effects, but the effect needs to be further verified. Li Kai pointed out that at present, there is no scientific demonstration in China that oral sunscreen pills, sunscreen sugar, etc. can play a sunscreen role on the human body, that is to say, the dream of sunscreen through food is not yet realized.

Sun protection is not needed in summer or outdoors

A number of dermatologists pointed out that the public should still use shelter or sunscreen as the main means of sunscreen.

Sun protection, mainly against the ultraviolet rays in the sun. According to the wavelength, ultraviolet can be divided into ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC), among which ultraviolet C is almost absorbed by the ozone layer, and UVA and UVB have a greater impact on human body.

The main harm of UVA is photoaging, that is, the skin is prone to wrinkle and aging after long-term exposure, and even may lead to the occurrence of skin cancer. UVB can cause skin redness, swelling, peeling and other sunburn. DNA damage of skin cells is the key factor to cause skin cancer.

It should be noted that the incidence and death rate of non melanoma skin cancer in men are higher than that in women. It has nothing to do with mens general lack of attention to sun protection. Li Kai said.

Sunscreen with physical properties mainly includes titanium dioxide, Zinc Oxide and other ingredients, which can adhere to the skin surface in the form of particles, reflect or refract the ultraviolet rays, so as to achieve the effect of sunscreen. This kind of sunscreen is usually suitable for pregnant women, children, the elderly and people with sensitive skin Li explained that chemical sunscreens usually contain ingredients such as p-aminobenzoic acid, which need to be absorbed by the skin to combine with proteins in the skin to absorb ultraviolet rays. Therefore, the chemical sunscreen needs to set aside the time for skin absorption. It is generally recommended to apply it half an hour before going out.

What are the tips for sunscreen? Li Wei said that in summer, we should try to avoid going out in the period with the strongest ultraviolet rays at 10-14 oclock. When we have to go out, we suggest two kinds of sunscreen methods to go to the battle together, i.e. sunshade and sunscreen should be applied, and sunscreen is recommended to be applied twice in a row, every 2-3 hours; when participating in underwater activities such as swimming and diving, we should choose waterproof sunscreen. In addition, many doctors also stressed that we should adhere to sun protection in all seasons. In all seasons of the year, as long as the activity is in a sunny place, it will face the UV damage, no matter indoor or outdoor. Li said that although the UV is stronger in summer, sun protection should not only focus on summer and outdoor areas, ignoring winter, spring and autumn, and indoor areas. She suggested that the sun protection factor (SPF) of sunscreen used in summer should be greater than 30. In other seasons, spf15-20 sunscreen can be selected as appropriate.
