A long time ago, we had never used " pleasantly " Or " make warm " To describe the sunshine in midsummer. Now, lady liking to be beautiful more and more realizes clearly, the pale and delicacy that the ultraviolet ray of the sunshine often robs the skin like thief, they dislike the sun in summer further, want to escape the chasing of the ultraviolet ray by every possible means. Look, with the promotion in summer, there are quite a lot of centres about becoming the topic in sun-proof noun, the highest one is surely to go out of mirror rate among them" SPF " (used after a verb to indicate the completion of an action).SPF (KPF) of 's hair-dressing articlesSunshine of is known " Steal " Go moisture of hair in the keratin, suffer to tan by the sun sunlight, can often turn to be yellow, fragile while being beautiful to take place, there is no elasticity at all. It is greater that while swimming beautiful to take place the injury received. Under the influence of the ultraviolet one, the chemical reaction that a kind is like bleaching agent will take place in water, in outdoor swim, for a long time summer, the color of the hair will turn light, the hair quality will become bad, this reason causes. So beautiful to take place and take to prevent suntan. is so, there is " KPF " (Keratin Protection Factor) Appearance. Much hair-dressing articles mark SPF (Sun Protection Factor) too on the market ,The sun-proof ability to show products, this refers to protection intensity of the correct cortex. KPF specially directs against the dry protection index. KPF index is divided into 10 grades, if want instead of preventing suntan and protecting to the scalp to the hair, should choose to mark the products of KPF index.SPF (SPF) of 's clothes , with the development of science and technology, garment have sun-proof ability, quite sound like Arabian Nights, but this is really a fact.The sun-proof ability of 's clothes depends on the material at first, secondly it is the color and luster. SPF value of the cotton quality clothes is about 15-40; SPF value of the light-colored clothes of polyester is about 7-10; SPF value of the knitted light-colored clothes is about 4-9. SPF value, namely sun-proof coefficient, calculates like this: The skin of general yellow can keep out sunshine for 15 minutes but not burn on average, use the mere articles of antiultraviolet of SPF15, have about 225 minutes (15 minutes * SPF15) Sun-proof for time,mean so SPF whether there aren't skin.A appearance with detergent of the sun-proof function of , strengthen the sun-proof ability of the clothes even more. This kind of product has added and suitable for ultraviolet absorbent of the whole wave band in the detergent of fabric, it and cotton, mao and polyamide fibre fiber,etc. have good affinity, and other washing compositions can be well merged, wash and circulate through the simple fabric, to strengthen fabrics to ultraviolet blocking function. The surface fabric carries on effective separation to the sunshine, the skin is protected naturally.SPF (SPF) of the cosmetics SPF value, namely SPF, means the time multiple that the skin keeps out the ultraviolet ray. It calculates like this: The skin of general yellow can keep out sunshine for 15 minutes but not burn on average, use the antiultraviolet articles of SPF15, have the sun-proof time of about 225 minutes. Say objectively, the level of SPF reflects the size of the ultraviolet protective capacity of the sun-proof products. SPF high index have, protection not offered big, the intersection of SPF and growth and reject ability to block ultraviolet ray, directly proportional to of value.Generally speaking , SPF of the sun-proof product of low grade is SPF2-6 the most, the medium-sized sun-proof product is SPF6-8, the higher sun-proof product is SPF8-12, the products in 12-20 ranges of SPF value are Gao Qiang's sun-proof products, the products among 20-30 of SPF value, in order to exceed Gao Qiang's sun-proof product. , in the past, to high coefficient have sun-proof product, texture, and sense of touch glue oily, airtight, oily skin in fear of avoid as. It is fine now, though the coefficient of the sun-proof new product is a bit high day by day, most brands well eliminate the greasy defect, the customer needn't worry being airtight again. The sun-proof products of Lancome, SK-II, Arden all have good behavior in this respect.How is chosen the appropriate SPF valueThere are two kinds of sun-proof product commonly used sun-proof pharmaceuticals that pays attention to UVA: Ultraviolet absorbent and ultraviolet ray shield pharmaceuticals (the ultra tiny powder substantially as oxidizing titanium and oxidizing zinc two times) . It is impossible that SPF is up to more than 20 products and does not include and oxidize titanium two times. Sun-proof pharmaceutical has certain amazing function on the skin while absorbing the ultraviolet ray, if ultraviolet absorbent is excessive, will also become the burden of skin, so, we should not pursue the products of the high SPF value blindly, but should confirm according to one's own job and concrete environment for use.The person of skin of 1, general type, SPF value suitable for 8-12; 2, to the mere sensitive person, SPF value suitable for 12-20;Whether 3, skin of sensitiveness should select the sun-proof product that plants fill a prescription or contain two sun oils which oxidize the titanium, can also use and contain vitamin E and products not including preservative, vitamin E resists and shines efficiency quite high, lubricated composition that have it and purify function, can neutralize because cell led to the fact to dry in the sun damage. 4 , use fruit at the sour skin care product, should cooperate with sun-proof the intersection of coefficient and relatively high getting physical sun-proof product, prevent the new born skin from being injured. Because the sour skin care product of fruit will make the skin thin, relatively fragile, is not able to bear the ultraviolet ray. 5, contacting the working clan of the sunshine only on the road on and off duty, SPF value is in under 15, rely mainly on the fact that the face prevents suntan; 6, while swimming on the sight-seeing, seashore of field, people's skin totally uncovers under the sunshine, SPF value of the sun-proof product should be above 30. Had better select the waterproof sun-proof skin care product for use while swimming, however, this kind of product is mostly that oil charter water emulsifying type, should not be multi-purpose. 7, ultraviolet ray shine in the more strongly season, the higher sun-proof product SPF values selected for use should be;In addition, the pale one of complexion had better select the sun-proof product of SPF over 30 for use, prevent the production of the spot in . The partial and deep one of skin, can adopt the sun-proof product of SPF 15 on ordinary days.
