Clobetasol Proprionate 25122-46-7 Raw Powder for Treating Skin Disorders
Clobetasol propionate is classed as a very potent topical corticosteroid. Topical corticosteroids are also referred to as topical steroids. Topical steroids are used in addition to moisturisers (emollients) for treating inflammatory skin conditions such as eczema and dermatitis. A topical steroid is used when patches of eczema or dermatitis flare up. Clobetasol propionate relieves the symptoms of a flare-up by reducing inflammation, itching and redness. It is not a cure for the condition, but it will help to relieve the symptoms.

Clobetasol propionate is used for the treatment of various skin disorders including eczema, herpes labialis,psoriasis, and lichen sclerosus. It is also used to treat several auto-immune diseases including alopecia areata, vitiligo, lichen planus (auto immune skin nodules), and mycosis fungoides (T-cell skin lymphoma). It is used as first-line treatment for both acute and chronic GVHD of the skin.
Clobetasol proprionate is used cosmetically by dark-skinned women for skin whitening, although this use is controversial. The U.S. Food and Drug Administration has not approved it for that purpose, and sales without a prescription are illegal in the U.S. Nonetheless, it is often sold in U.S. retail beauty supply stores and on the internet. It is also sold internationally, and does not require a prescription in some countries. Whitening creams with clobetasol proprionate, such as Hyprogel, can make skin thin and easily bruised, with visible capillaries, and acne. It can also lead to hypertension, elevated blood sugar, suppression of the body’s natural steroids, and stretch marks, which may be permanent.
Clobetasol propionate is with mercury and hydroquinone "amongst the most toxic and most used agents in lightening products." Many products sold illegally have higher concentrations of clobetasol propionate than is permitted for prescription drugs.
How it works?
Clobetasol belongs to a class of drugs called topical corticosteroids. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
Clobetasol propionate cream and ointment are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparations.
Apply a thin layer of clobetasol propionate cream or ointment to the affected skin areas twice daily and rub in gently and completely.
Clobetasol propionate cream and ointment are super-high potency topical corticosteroids; therefore, treatment should be limited to 2 consecutive weeks, and amounts greater than 50 g per week should not be used.
