Cream for a century of Hyalu B5 from La Roche Posay.

La Roche Posay is the pharmaceutical brand from France based on thermal water from a source with the name of the same name. This name of the area, popular medical resort. Thermal water from La Roche Posay is rich with selenium (and other minerals) and is shown for treatment of dermatitis and dry skin.
I love the pharmaceutical cosmetics based on thermal waters. It is special! The majority of creams imeet up to 70% of water in structure. And if it is thermal water what can be better?

Cream for a century of Hyalu B5 got to me in the form of a sampler from drugstore where I ordered other means. Usually I am skeptical with responses on samplers. Well it is possible to understand, having used a sampler? Only 1.5 ml... But it turned out that the bag was enough for me for 12 applications in the mornings. Therefore I take courage to write about the impressions and to support them with scientific data.
Type responses: good cream, was pleasant to me, - I do not write. Always each means has pluses and minuses.
This cream not anti-aging, it is suitable for age 25+, for dry, dehydrated, inclined to hypostases to skin a century and areas under eyes. From the name it is possible to understand what active ingredients in it: it is hyaluronic acid and B5 vitamin (pantenol, being expressed more clear).
Pantenol in the list of ingredients is in 1/3 from the beginning. It here enough.
Pantenol is made from d-panto-lactone and a spirit form of pantothenic acid. Pantothenic acid is not alien to our organism, it is in all living cells and is very important for a normal metabolism and products of hormones.
Pantenol turns into B5 vitamin as soon as contacts to living cells (skin for example). But if to apply on hair which have no living cells it will remain in an invariable look. For hair it is used as a humidifier. And for skin differently: gets into deep layers, participates in moistening, stabilizes a metabolism and tones up. Also, reduces inflammations, burning, irritation of skin. Ideal means for treatment of burns, heals skin.

As for other active agent - hyaluronic acid, all know about its most powerful moistening qualities, about its ability to hold moisture on the surface of skin. Hyaluronic acid is a natural polysaccharide which is in all tissues of our body.
In cosmetics hyaluronic acid of plant origin is used.
In this cream 2 types of hyaluronic acid. One - the most popular is sodium hyaluronate. Has large molecules and gives superficial moistening of skin.
Another - hydrolized hyaluronic acid - the low-molecular hyaluronic acid capable to get more deeply than a horn layer and to moisturize the skin from within.

In active ingredients of cream shea butter, apricot kernel oil, quartz (it is important for elasticity and smoothness of skin), stearates (the fatty acids moisturizing the skin), amino acids and also one interesting substance, double Acetyl-Dipeptide-1 Cetyl Ester peptide appears. It is the product including acetyl ester of a tirozin from Dipeptide-1 and cetyl ester of an arginin from Dipeptide-1.
Simple words: it is the double proteinaceous molecule of a tirozin and an arginin having function of "the envoy of tranquility and muscular relaxation". It stimulates nervous cells of skin to release met-enkephalin (the substance killing pain and weakening).
Acetyl Dipeptide-1 Cetyl Ester can signal cells of our skin "to relax" and can quickly remove the irritation proceeding from a heat, chemical discomfort or a mechanical stress.
It is also stated what can prevent deepening of wrinkles and mimic lines, thanks to, relaxing muscles, to action.
In network data of clinical experiences on human skin are published (at volunteers).
During tests skin was subject to irritation kapsaitsiny (chili pepper substance).
Two molecules Acetyl Dipeptide-1 Cetyl Ester and 4-T-Bulylcyclohexanol were used to remove a condition of burning and irritation. Both substances coped with a task, but the second made it slightly better, quicker and more qualitatively. Control time of 15 minutes.
4-T-Butylcyclohexanol contains in Eucerin R/Ultra-Sensitive soothing cream.

Acetyl-Dipeptide-1 Cetyl Ester has molecular weight 603.848g/a pier. It means that for penetration through a horn layer of skin it needs substance - the conductor. Is present at structure glycol which has properties of the conductor is sawn through.
Dipeptide is very popular, he can be met in many other cosmetics. In particular, at Caudalie Resveratrol lift, at Bioten Perl cream and others.
Apparently on a photo, consistence of cream quite dense and dense, color light - beige, but on skin is not noticeable when it is absorbed. A cream consumption very economic, rather absolutely small quantity for drawing. I put with the fingertips which are driving in with movements, beginning from an external corner of an eye to internal. I do not rub, I do not stretch skin. I do not apply to clean skin, and over day serums when those are absorbed. Cream does not clash with one of serums, and cosmetics from above on cream lays down without problems and well keeps during the day. Tested cream in hot weather about +30' with high humidity of air (higher than 60%). Cream resistant, does not roll down, does not flow, does not cause irritation or hypostases. Everything is individual, of course. For this purpose there are also samplers.
Has no fragrance, it is great advantage. Also, has no as a part of mineral oil, alcohol of denatured alcohol, parabens, formaldehyde.
Structure on the basis of thermal water, glycerin and shea butter, with addition of the active and connecting ingredients.
From structure minuses - existence glycol propylene (it is more preferable propanediol), a dimetikona (but thanks to it cream is perfectly distributed on skin and is spent economically, visually improves appearance of skin), VNT preservative (it is better for pregnant women to avoid it in cosmetics and foodstuff as gets through a placenta), phenoxyethanol (preservative of broad application), polysorbate 80 (the it is higher than a figure, the there is more harmful substance). Personally I accept PEGI in compositions of cosmetics, without them will very seldom meet the working worthy product. But this personal record of everyone what to be afraid of and what is not present in means of cosmetics.
In general, I am happy with both structure, and feelings from use, and consistence of cream. The fact that it the worker also positively influences a condition of skin at me does not raise doubts. After drawing skin around eyes looks gentle, there is no tightness, but also there is no feeling of what - that superfluous on the surface of skin, a fat film or a greasy luster. If I sweat, cream does not spread, does not dissolve my make-up, ink does not imprint under eyes. He will not remove a wrinkle and will not disguise, but will moisturize the skin, will make smooth and pleasant. And it is possible, will slow down developing of the new wrinkles and deepening which are already existing thanks to "tranquility peptide" Acetyl-Dipeptide-1 Cetyl Ester.
The cream price not budgetary, but there are discounts, actions, online offers. Cream was pleasant to me, its advantages exceed shortcomings. Most likely, I will buy the full version of cream.
