Azelaic acid

Azelaic acid ādas kopšanā: Anti-inflammatory, comedolytic, tyrosinase inhibitor. 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 Azelaic Acid.

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 dicarboxylic acid found naturally in wheat, rye and barley and produced industrially for use. It sits on the boundary between cosmetic and medicine: at 15% and 20% it is a licensed prescription treatment for rosacea and acne in many countries, while cosmetic products typically use around 10%. Same molecule, different regulatory status, and quite different expectations.

Ko tas dara uz ādas

It does four useful things at once, which is unusual. It normalises the way cells shed inside the follicle, so plugs form less readily. It suppresses the bacteria involved in inflamed acne. It calms inflammation, which is why it helps the papules and pustules of rosacea. And it inhibits the enzyme that starts pigment production, so the brown marks left behind by old spots fade faster than they otherwise would.

Cik vērti ir pierādījumi

Pierādījumi:Spēcīgs

The prescription strengths are properly supported for rosacea and for acne, with the pigment benefit well described as a bonus rather than a headline. The evidence for a 10% cosmetic version is an extrapolation downward: plausible, gentler, slower, and not the strength that was studied. Anyone reading trial results for 15% gel and buying a 10% cream should expect less.

Kā to lieto

Applied thinly to the whole affected area rather than dabbed on individual spots, once or twice daily, and judged after two to three months rather than two weeks. The texture is grainy and it can pill under sunscreen, so let it settle. It is one of the few actives that suits both inflamed acne and post-inflammatory pigmentation without a separate product for each.

Tipiskā koncentrācija parastā lietošanā:10% cosmetic, 15-20% medicine. Tas ir tirgus apraksts, nevis ieteikums, un tā nav deva.

Kas uz to reaģē

Transient stinging, tingling and mild burning in the first weeks are described by a substantial minority of users, and usually fade. Unlike hydroquinone it does not lighten normal surrounding skin, so it will not leave pale patches.

Grūtniecība un barošana ar krūti

Parasti tiek uzskatīts par pieņemamu

Azelaic acid is one of the treatments most often kept when other acne actives are stopped in pregnancy. Because the effective strengths are medicines, the decision belongs with your doctor or midwife, who will also weigh what else you are using.

Saules gaisma

Nav izmaiņu

It does not make skin more sensitive to sunlight. If you are using it for pigmentation, though, sun exposure is the thing driving the pigment, so sunscreen is what makes the treatment work rather than a precaution against it.

Noteikumi un marķējums

Permitted in cosmetics, but the 15% and 20% products are authorised medicines in most European countries and are supplied through a pharmacy. A cream sold online at 20% without that authorisation is not a stronger cosmetic, it is an unlicensed medicine.

Ar ko tas sader un ar ko ne

It sits well with niacinamide and with a gentle cleanser, and it is the usual choice when a retinoid is too irritating or is off the table. Combining it with an exfoliating acid rarely adds anything except stinging.

Viena lieta, ko cilvēki saprot nepareizi

The myth is that it is a mild botanical because it occurs in grain. It occurs in grain the way sugar occurs in fruit — the version in your tube was made in a factory, and at treatment strength it is a regulated medicine with a real side-effect profile. Being naturally occurring says nothing about how strong or how gentle a substance is.
