Hydroquinone

Hydroquinone odos priežiūroje: Skin-lightening agent (not a permitted EU cosmetic). Ką jis daro ant odos, kiek iš tiesų stiprūs įrodymai už teiginio, koncentracijos įprastai naudojant, kas į jį reaguoja ir kokia jo padėtis nėštumo metu bei saulėje. Ant etiketės jis nurodomas kaip Hydroquinone.

Etiketėje:Hydroquinone. Taip pat vadinama:Found in illegally imported "whitening" creams.

Tai sudedamųjų dalių informacinė medžiaga, o ne diagnozė ir ne gydymo planas. Ji aprašo, kas yra tos medžiagos ir ką patvirtina paskelbti įrodymai; ji nepasako, kas yra jūsų odai ar ką ant jos tepti. Išbėrimas, kuris plinta, skauda, varva, nenurimsta arba kurį lydi bloga savijauta, yra priežastis kreiptis į gydytoją ar vaistininką, o ne keisti serumą.

Kas tai yra

A phenol that blocks tyrosinase, the enzyme that starts melanin production, and reduces the pigment cells' output while it is used. It was for decades the reference treatment for melasma and stubborn pigmentation, and it works. It is on this list not as a recommendation but because people meet it: it is one of the substances most often found in skin-lightening creams bought online or brought back from abroad.

Ką jis daro ant odos

It suppresses pigment production wherever it is applied, including on skin you did not intend to lighten, which is why patchy pale areas around a treated spot are a recognised outcome of careless use. The effect reverses when you stop, so the treatment is a course with an end, supervised, not a product you use indefinitely.

Kiek verti įrodymai

Įrodymai:Stiprus

The efficacy evidence is strong and old. The safety questions are what changed the rules: prolonged, unsupervised, high-strength use — particularly on darker skin — can cause exogenous ochronosis, a blue-black discolouration that is difficult to treat and can be permanent. That is the outcome that supervision is meant to prevent.

Kaip jis naudojamas

In countries where it is available it is a prescribed course of treatment with a defined duration and follow-up, not an over-the-counter cosmetic. If pigmentation is the problem, the cosmetic and prescription alternatives — azelaic acid, retinoids, vitamin C, tranexamic acid, and above all daily sun protection — are the route your clinician will take first.

Tipinė koncentracija įprastai naudojant:Not permitted in EU skin cosmetics. Tai yra rinkos aprašymas, o ne rekomendacija, ir tai nėra dozė.

Kas į tai reaguoja

Irritation, contact dermatitis, a temporary halo of lighter skin around the treated area, and with long unsupervised use the ochronosis described above. Every one of those risks rises when the product is unlabelled and the concentration is unknown.

Nėštumas ir žindymas

Nutraukiama nėštumo metu

Not used in pregnancy. Pregnancy-related melasma is common and frustrating, and the safe approach is rigorous sun protection plus treatments your clinician approves — not an unlabelled cream from an online marketplace.

Saulės šviesa

Jautresnis saulei

Skin with suppressed pigment production burns more easily, and any pigmentation treatment fails without sun protection because ultraviolet exposure is what drives the pigment in the first place.

Taisyklės ir ženklinimas

Hydroquinone is prohibited in cosmetic products in the EU except in professional artificial nail systems; it may not lawfully be sold here in a face cream. In the United States it is regulated as a medicine rather than a cosmetic. Imported skin-lightening creams are a recurring subject of national safety recalls, and the same products have repeatedly been found to contain potent steroids or mercury as well. The World Health Organization publishes an information sheet on mercury in skin-lightening products.

Su kuo jis dera ir su kuo ne

Not applicable in the EU. If you have brought a product home from abroad and it has lightened your skin quickly, that speed is a reason to have it checked rather than a reason to continue.

Vienas dalykas, kurį žmonės supranta neteisingai

The myth is that a cream sold openly on a large marketplace must be legal and tested. Skin-lightening creams are among the most frequently flagged product categories in European safety alerts, precisely because unlabelled hydroquinone, potent corticosteroids and mercury keep turning up in them. If a cream lightens skin within days, something in it is not a cosmetic.
