The aesthetic gout of Asian dominant, make increasing person white to the skin fair-skinned, had new pursuit, become a light in vain, make the wish of the one numerous person that beg the United States.
Why does Asian skin slant yellow?
The melanin content in the skin is concerned with the rate that accepts insolation already, also concern with heredity. The Gao Wei of the European north with white traceable faint sunshine spends an area, the melanin in deciding its skin hereditarily is little, this is helpful for passing through as far as possible much ultraviolet ray vitamin D is generated in order to help inside body, stimulative calcium is absorbed character.
And xanthous the middle latitude area that forms Yu Yazhou, content of the melanin in skin of genetic element decision is more than the white man, present yellow color of skin.
Summer arrived, sun irradiation time lengthens, the skin is suntanned more easily.
Say so, want to bleach, first job is to had been done prevent bask in the job.
The violet outskirt of the above of long 280nm of solar and main You Bo of earthly surface is comprised to the red outskirt of 1mm less than, among them ultraviolet ray (UV/UVR) occupy about 6% , visible light is occupied about 52% , infrared ray is occupied about 42% , UV gets consensus already to cutaneous harm. UVR wavelengh is in 100 ～ 400nm. According to wavelengh limits and biologic effect, UVR cent is the following 3 wave band:
Shortwave ultraviolet ray (UVC) : Wavelengh 100 ～ 280nm, penetrable ability is weak, be absorbed by atmosphere ozonosphere entirely, cannot arrive at earthly surface.
Medium wave ultraviolet ray (UVB) : Wavelengh 280 ～ 315nm, can penetrate aerosphere, be cut off easily by glass, can arrive at cuticular base layer, biologic effect is powerful, for 100 times of UVA.
Long wave ultraviolet ray (UVA) : Wavelengh 315 ～ 400nm, penetrable capability is strong, can wait through frivolous clothing and other articles of daily use, glass, can penetrate skin surface layer, arrive at dermal layer.
The skin is long by illuminate, can appear all sorts of undesirable skin reaction
Erythema reaction: Main show is insolation place occurrence erythema, strut, the condition may produce cost off a skin badly.
The skin is black change: The grey black splash that expression is clarity of illumination place border, according to pigment occurrence time, can divide for immediateness sex black change, durative black change and defer sex is black change.
Skin smooth ageing: Long-term and solar illuminate can quicken skin consenescence, this one change basically is cause by UVA. Show appears to expose place skin solely grow in quantity of coarse, furrow and pigment are deepened, skin flexibility is reduced, outspread or blood capillary is proliferous.
Immune function is unusual: The skin gets after ultraviolet illuminate, not only can cause illuminate place to produce skin smooth allergy to react, the function that still can cause local skin and systemic immunity system is unusual.
Long solar illuminate, self-evident to cutaneous harm, place basks in the job to must have been done in case, how has been that done prevent bask in the job?
Keep out is prevented bask in
The fabric product such as sunshade, sunbonnet and clothings but direct keep out is solar. Taller, color jumps over the density that knit gauze deep, or add have prevent bask in coating, its ultraviolet ray absorbs ability stronger, prevent it is better to bask in the effect.
Prevent bask in cosmetic
Prevent basking in an agent is the absorption that uses pair of light, reflex or scattering action, avoid the material that gets specific UV harm in order to protect the skin. Prevent well bask in cosmetic to prevent bask in the effect to be cut truly, be able to bear or endure suffer a gender tall, produce stimulation and allergy not easily; Easily daub, permeability is good.
Of course, black to inherent skin for the person beg the United States that perhaps has suntanned, bask in through preventing merely get effective very small, can pass smooth needle of cure beautiful water to come back in vain.
Water is smooth therapeutics of the germinal layer in injecting to be called again, embryo forms 3 germinal layer, inside germinal layer, medium germinal layer, outside germinal layer, and the person's skin is by outside germinal layer and in germinal layer become divided comes, skin cent is skin and derma, cuticular by outside germinal layer splits up and come, dermal by in germinal layer splits up and come, water smooth needle with respect to cortex of action Yu Zhen, therapeutics of the germinal layer in be called so.
The material curative effect of water smooth needle basically sees includes part, the Bo make water that the main body composition of water smooth needle is small cross-linking or blame cross-linking is acerbity, and in the connective tissue of human body of consist in of acerbity itself of Bo make water and dermal layer, develop inside body puissant ensure the water, space outside preserving a cell, adjust permeate pressure, the important physiology function of rehabilitate of lubricant, stimulative cell.
According to diverse demand, besides acid of Bo make water, other part should inspect skin of the person that beg the United States particular case is added, additive part is different, hairdressing effect also each are not identical.
Want to become the son with whole the lightest market, the skin is black how to go, summer arrived, make the best of time to rise in vain.
