Description
Technical field
The invention belongs to sun-proof technical fields, and in particular to a kind of system of the suncream containing after-sun function microcapsules
Preparation Method.
Background technology
UVA and UVB in sunlight can penetrate skin corium, and skin is made to generate phenomenon after the solarizations such as sunburn, decortication, tanned, and then
Skin is made to shift to an earlier date aging, some irremediable injuries are caused to skin, if influenced for a long time by UVA and UVB, it is also possible to
Lead to cutaneum carcinoma.
Skin is come into being by tanned and sunburn, the suncream product for being added to sun-prevention component in order to prevent.However even if
Using suncream carry out how strict protection, it is also not possible to the injury that very isolation ultraviolet is brought, after-sun are long
Important reclamation activities after time solarization, however useful effect can just be played by being repaired in the short time only after solarization, such as
Fruit is repaired again after solarization a whole day, and good repairing effect will be not achieved.
Current suncream function is more single, and only with sun-proof function, it is dual not have both sun-proof and after-sun
The suncream of effect is saled in the market, and has certain gaps in market.However, existing sun-prevention component and after-sun into
/ there is certain reciprocal effect relationship, i.e., when the two is coexisted in a kind of product, there may be certain counteracting to make
With so that the sun-proof function of suncream weakens, and the system of suncream is made to become unstable, it is not easy to be coated uniformly on skin
On.
Invention content
For deficiencies of the prior art, the technical problems to be solved by the invention are：One kind how is provided to contain
