Glycerin

Glycerin ādas kopšanā: Humectant. Ko tas dara uz ādas, cik spēcīgi patiesībā ir pierādījumi aiz apgalvojuma, koncentrācijas parastā lietošanā, kas uz to reaģē un kāda ir situācija grūtniecības laikā un saulē. Uz etiķetes tas parādās kā Glycerin.

Šī ir sastāvdaļu uzziņu informācija, nevis diagnoze un nevis ārstēšanas plāns. Tā apraksta, kas ir šīs vielas un ko apstiprina publicētie pierādījumi; tā nepasaka, kas ir jūsu ādai vai ko uz tās likt. Izsitumi, kas izplatās, sāp, tek, nepāriet vai ko pavada slikta pašsajūta, ir iemesls apmeklēt ārstu vai farmaceitu, nevis nomainīt serumu.

Kas tas ir

A small three-carbon alcohol with three hydroxyl groups, which is what makes it grip water so well. It is produced as a co-product of soap-making and of vegetable oil processing, and it is one of the oldest and cheapest ingredients in the industry. It appears near the top of the ingredient list of a very large share of moisturisers, and it is doing more work there than most of the actives further down.

Ko tas dara uz ādas

It draws and holds water in the outer layer, and beyond simple water-binding it helps the surface cells shed properly and supports the enzymes that repair the barrier. Skin with enough glycerin in it is more flexible, less itchy and less prone to the fine cracking that lets irritants in. Its effect is on the quality of the outer layer rather than on any deeper process.

Cik vērti ir pierādījumi

Pierādījumi:Spēcīgs

This is the best-evidenced ingredient on the list and almost nobody markets it. Decades of controlled trials in dry skin and atopic dermatitis support it, and it is so reliable that it is often used as the comparator against which newer moisturising ingredients are tested. The evidence base is larger than that behind most of the actives that get the front of the label.

Kā to lieto

In a moisturiser, applied to skin still damp after washing. It is standard in the 3-10% range; much higher concentrations feel sticky and are used deliberately in some products. As with any humectant it works best with something occlusive over or with it, which is how a moisturiser is formulated in the first place.

Tipiskā koncentrācija parastā lietošanā:3-10% in moisturisers. Tas ir tirgus apraksts, nevis ieteikums, un tā nav deva.

Kas uz to reaģē

Extremely well tolerated; irritation and allergy are both rare. The usual complaint is stickiness at high concentrations, especially in humid weather.

Grūtniecība un barošana ar krūti

Parasti tiek uzskatīts par pieņemamu

No pregnancy concerns. A plain glycerin-based moisturiser is the safest thing on any bathroom shelf and is the right base for a pared-back pregnancy routine.

Saules gaisma

Nav izmaiņu

No effect on light sensitivity.

Noteikumi un marķējums

Not restricted. It is also a food ingredient and a pharmaceutical excipient, which is a useful indication of how thoroughly it has been assessed.

Ar ko tas sader un ar ko ne

Everything. Its most valuable pairing is with an occlusive such as petrolatum or dimethicone, which is exactly how most good moisturisers are built: a humectant to hold water and an occlusive to keep it there.

Viena lieta, ko cilvēki saprot nepareizi

The myth is that in dry air glycerin pulls water out of the deeper skin and makes dryness worse. That effect is a laboratory observation with pure glycerin under extreme conditions; in a real formulation, alongside occlusives and applied to damp skin, the clinical trials show benefit rather than harm. If a glycerin product feels drying, the missing ingredient is the layer over the top.
