Unique and unusual means.
Serums with vitamin C exists very much that it is easy to be lost among brands and their products. Each producer offers that he considers the best, by different criteria.For me there is no problem with the choice: I apply 2 main criteria - structure of means and its price.
Here in this serum everything is balanced---structure/price are adequate. And I am going to tell why.
The producer promises us improvement of a condition of skin---it will look younger, will receive moistening, the elasticity will increase and young shine will appear. They checked it by practical consideration within 4 weeks with participation of 30 women.
It is good that means was not tested for animals, and on people - volunteers.
But, if the structure is truthful, then I and so believe them: the efficiency of ingredients is proved more than once.
We are recommended to apply serum after clarification of skin to slightly moist skin, to wait for 5 minutes and to block cream.
It is not desirable to use together with acids and retinoida. Here I am ready to argue.
In usage time of serum, it is necessary to put protection against the sun. It is right! Protection is necessary always, irrespective of serums.
Structure at serum very interesting!
At first sight, anything special: water, Ascorbic acid and glycerin---here a basis.
But Ascorbic acid very unstable - water and oxygen destroy it. Cosmetic brands around the world try to stabilize it by means of other substances, adding them to formulas.
And all the same, approximately in 3 months after the beginning of use, Ascorbic acid is oxidized and loses the qualities.
Excipients can only slow down oxidation process, but not stop it.
As stabilizers of ascorbic acid serve 2 known substances: vitamin E has to be not less than 1% as a part of a formula and ferulovy acid in number of 0.5%.
Here they are available in the necessary concentration.
One more stabilizer of vitamin C in this serum---zinc sulfate (compound of zinc and sulfurovy acid), has the molecular mass of 161.47 g / like, so easily gets through a horn layer of skin.
Except ferulovy acid which strengthens effect of vitamin C by 4 times here we see one more substance---Tyrosine---the amino acid stimulating production of protein with cages. Together with ascorbic acid, stimulates fibroblasta to produce collagen.
Its molecular weight 181.19g/like, easily gets through a horn layer.
But the tirozin has one feature - it increases production of melanin skin. That is why personally I use this serum only in the evenings.
There is a version: if we need to level visually tone of skin, then a little additional melanin (easy suntan) it carries out.
But me suntan to anything.
Serum also contains the substances calming skin.
Betaine is a humidifier, regulates water balance of skin and helps it to adapt to loss and completion of moisture. Molecular weight 117.15g/pier.
Together with Beta-glucan (polysaccharide) which helps skin to hold moisture even better than hyaluronic acid, Betaine works even more effectively.
The known pro-vitamin B 5 - Pantenol---reduces inflammation and helps skin restoration.
Hyaluronic acid - a skin humidifier.
Extract of leaves of an aloe the belief - calms irritations.
Coenzyme Q10 (ubiquinone) - an antioskidant.
In this formula at me stability of this ingredient raises doubts. As ubikhinon easily collapses on light and under the influence of oxygen. And packing with the batcher - the pipette not absolutely successful to keep qualities of antioxidants.
In general, I consider structure interesting and working, rationally grouped.
As I bought serum in shop of cosmetics, sellers could not answer me a question of its level rn. Then I asked a question to the producer by means of e-mail.
In several days I was kindly answered that level rn at serum 5.22. It means that it slightly sour, but not is enough to have strong impact on skin. Despite the high content of vitamin C in pure form, it is not so effective as other serums having rn 3.5.
But, on the other hand, this serum does not cause the slightest irritation of my skin, does not enhance redness from a couperosis, on the contrary positively influences it. It is important to people with sensitive skin.
One more positive moment - this serum can be applied in the morning and in the evening, without danger to get burns. Also, it is possible to combine it with peptide serums / creams, with retinoida, and even with acids.
I combine!
Serum has consistence slightly more densely than water and transparent by sight. For usage time it did not change, did not darken and no smell is felt.
The bottle comes to an end, I use it since February 15 every other day, in the evenings. That is, nearly 2 months. Serums with ascorbic acid are recommended to be used as soon as possible, without being sorry because she will lose the qualities.
I put 10% of The Ordinary after lactic acid. I give to lactic acid of minutes 20, I apply serum with vitamin C, again I give a little time and I block cream with the glycoleft acid and rn about 4.
After putting serum I feel absolutely easy pricking, there is no reddening of skin.
In the evenings, when I do not apply acid, I apply serum with vitamin C after clarification to moist skin (I blot it with a towel, I do not wipe dry), as well as the producer recommends. I give time to work and I put retinoid. Then the usual moisturizing cream.
As leaving at me complex, I cannot tell whether this concrete serum keeps the promises. And to make clean experiments me does not pull. But at my leaving there is always this or that serum with vitamin C in the form of ascorbic acid or derivative substance from it (the Askorbil type of glucoside, etc. forms).
I recommend serum to those who are afraid sour rn not to enhance sensitivity of skin and also to all who need this antioxidant in leaving.
Serum from Biovene is available at the price and quite qualitative on structure.
