For small babies, how do we protect their delicate skin from the sun? First, and most importantly, is to reduce the time of sun exposure. Our outdoor activities, as far as possible to avoid 11 a.m. to 2 p.m. this time, because this time the strongest ultraviolet rays. Second, must be in the sun when the activity, be sure to bring a broad-brimmed sun hat; wear long-sleeved clothes; the best choice in the sun can not be direct sunlight environment, such as under the eaves, trees, umbrellas, etc., to avoid direct exposure of skin in the sun. Third, the correct choice of clothes can also reduce the damage of ultraviolet rays. All clothes have the function of sun protection, but different colors and fabrics, the effect of sun protection is very different. In terms of color, red is the most able to stop ultraviolet light, because the red wavelength is the longest, absorbing the widest range of the spectrum, the most sunscreen; dark clothes than light sunscreen, white is the worst sunscreen color. In terms of fabrics, chemical fiber fabrics have the strongest ability to reflect UV rays, including polyester fabrics and stronger than acrylic fabrics; in natural fabrics, linen sunscreen effect is better than cotton and silk. Loose clothing allows for more air flow between clothes and skin, making it easier for sweat to evaporate, drier skin, and dry skin has a stronger sun protection function than moist skin. Therefore, it is very necessary to add some loose clothes of linen material to the baby in summer. Fourth, eating more sun-protective foods can also help babies reduce the damage of UV rays. Preferred foods rich in vitamin C. Vitamin C is the “eternal beauty holy grail”, can antioxidant, whitening, in tomatoes, kiwi, strawberries, oranges in a lot of content. Secondly, soy products are rich in phytoestrogens, which have a strong antioxidant effect and can also reduce the damage of UV rays. Finally, drink more water, so that the baby’s skin is fully moisturized, to better maintain the baby’s skin barrier function, the skin’s ability to protect against the sun will be stronger. Fifth, choose the right sunscreen. Sunscreen products according to its composition can be divided into physical sunscreen (reflecting UV rays) and chemical sunscreen (absorbing UV rays), the former is mainly titanium dioxide or zinc oxide, a large number of foreign studies have shown that these two ingredients do not penetrate the skin inside, very safe; the latter composition is a lot, mainly using chemical components to absorb UV rays into heat or molecular vibration. Nowadays, many products are mostly synthetic products that contain both. Now some of our friends like to choose products with high sun protection multiples. In fact, the SPF value only indicates the time multiplier to prevent UV burns, each increase in SPF 1 can increase the time of 15 minutes (SPF 20 = 20 * 15 minutes that there are 300 minutes of sunscreen time), SPF value and sunscreen effect is not correlated. And the higher the SPF and PA value, the more sunscreen ingredients their products contain, the greasier and more likely to cause contact dermatitis. Therefore, it is important to choose the correct SFP and PA value products according to your needs. In addition there are several noteworthy places, must be 30 minutes in advance to use sunscreen; sunscreen products need to be 2mg/cm2 thickness to achieve the proper sunscreen effect; SPF10 sunscreen products coated with 2 layers, sunscreen time or SPF10; swimming or sweating more, sunscreen time will be discounted, 1 to 2 hours need to reapply; generally think that the baby 6 months or more to use sunscreen is possible s, but before 6 months of age we do not have definitive data on whether sunscreen is needed. Although we are careful to protect our babies, sunburn can still occur. A mild sunburn is simply redness of the skin, with peeling on the nose, forehead and cheeks later in life. Mild sunburn immediately hide in the shade or other shady places, with cold towels wet compress sunburn, to replenish skin moisture, reduce skin temperature, reduce the role of skin burns; severe sunburn may appear blister, which requires professional dermatologists for anti-inflammatory, soothing and other treatment, in order to reduce sunburn as much as possible. In conclusion, sun protection for infants and children is very important for the health of the skin and requires more attention from mothers.
