Panthenol

Panthenol ādas kopšanā: Humectant, barrier and repair support. 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 Panthenol.

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

The alcohol form of pantothenic acid, vitamin B5, which skin converts into the vitamin itself. Pantothenic acid is a building block of coenzyme A, which cells use in fat synthesis — including the lipids of the barrier. In pharmacy it appears as dexpanthenol in the ointments used for nappy rash, chapped nipples, minor grazes and tattoo aftercare, which is where its reputation comes from.

Ko tas dara uz ādas

Two things at once. As a small water-binding molecule it hydrates the outer layer and reduces the tightness of dry skin. Beyond that it supports the repair of a damaged barrier and reduces the redness and irritation of skin that has been stripped, chapped or over-treated. It is the quiet ingredient in "soothing" products that is actually doing something.

Cik vērti ir pierādījumi

Pierādījumi:Mērens

Moderate: dexpanthenol has been tested in controlled studies of barrier repair and irritant dermatitis, including experimental models where skin is deliberately stripped and recovery is measured. The strongest data sit with the pharmacy-strength ointments rather than the 1-2% in a serum, but the direction is consistent and the risk of harm is close to zero.

Kā to lieto

Anywhere skin is irritated: after a retinoid ramp-up, after shaving, after sun, on chapped hands in winter. In leave-on products at 1-5%; in hair conditioners it coats and softens the fibre instead. It is a good default addition to a routine that keeps tipping into irritation.

Tipiskā koncentrācija parastā lietošanā:1-5%. Tas ir tirgus apraksts, nevis ieteikums, un tā nav deva.

Kas uz to reaģē

Very well tolerated. Contact allergy exists but is uncommon, and is most often reported in people using dexpanthenol ointments repeatedly on damaged skin, where any ingredient has more opportunity to sensitise.

Grūtniecība un barošana ar krūti

Parasti tiek uzskatīts par pieņemamu

No pregnancy concerns; dexpanthenol preparations are widely used during and after pregnancy for exactly the chapping problems that come with it.

Saules gaisma

Nav izmaiņu

No effect on light sensitivity. It is often used after sun exposure for comfort, which does not treat the damage — it treats the discomfort.

Noteikumi un marķējums

Not restricted in cosmetics. The pharmacy ointments are medicines and carry their own labelling.

Ar ko tas sader un ar ko ne

Excellent with ceramides and glycerin, and the standard partner for a retinoid or acid routine that has gone slightly too far. It also pairs well with niacinamide in a calming product.

Viena lieta, ko cilvēki saprot nepareizi

The myth is that it is a vitamin supplement for skin — that applying B5 does what a deficiency correction would. Pantothenic acid deficiency is essentially unheard of in a normal diet, so nothing is being corrected. Panthenol earns its place as a humectant and barrier-repair ingredient, not as nutrition applied to the outside.
