Skin Acne

Acne vulgaris is the result of several factors combined. The condition arises in the pilosebaceous units in the dermis, which consist of a hair follicle and associated sebaceous gland. These glands secrete sebum, a mixture of fats and waxes that protect the skin and hair by retarding water loss and forming a barrier against external agents. The hair follicle is lined with epithelial cells that become keratinised as they mature. 

Moderate more frequent papules and pustules, with possibly some scarring Severe nodular abscesses, leading to extensive scarring. 

Treatments must be used regularly for up to 3 months to produce benefits. 

If there is no adverse reaction, frequency of application may then be increased to twice daily. Several weeks of regular application are usually required to produce real benefit. If the lower strength is ineffective, the higher strength (10%) can be tried. 

It may also have some bacteriostatic activity and a direct anti-inflammatory effect on lesions. It is believed to enhance penetration into the skin of other medicaments, and is combined with sulphur in some formulary preparations.

A chemical heat pump was developed by use of two different types of adsorbents with C02 (41). Another example for material development is the synthesis of a mild abrasive powder for smoothing the human skin (acne patients) (11,16,42). ...

Oregon grape root (Mahonia aquafolium). This is one of the preeminent skin/acne remedies of the eclectic physicians. It is used for a wide array of skin problems, especially chronic ones involving liver congestion and a slight yellow hue to the skin. It can also be used topically as a wash for acne and acne rosacea. 

The toxicity of 2,4,5-T is very similar to that of 2,4-D. The symptoms are irritation of skin, acne-hke rash, somnolence, gastritis, fatty liver degeneration, and ataxia.

Anthralin [1143-38-0] is acetylated using acetyl chloride in toluene and a pyridine catalyst to furnish 1,8-dihydroxy-lO-acetylanthrone [3022-61-5], an intermediate in the preparation of medications used in treating skin disorders, such as warts, psoriasis, and acne (38). Sugar esters can be similarly prepared from acetyl chloride under anhydrous conditions (39). 

The toxicity of chloronaphthalenes requires that special attention and caution be used during their manufacture and use acne is the most common result of excessive skin exposure to them and the most frequendy affected areas are the face and neck (16). Liver damage has occurred in workers who have been exposed repeatedly to vapors, particulady to those of penta- and hexachloronaphthalene [1335-87-1] (17,18). Uses for the chlorinated naphthalenes include solvents, gauge and instmment duids, capacitor impregnants, components in electric insulating compounds, and electroplating stop-off compounds. 

The principal OTC pharmaceutical products include cold remedies, vitamins and mineral preparations, antacids, analgesics, topical antibiotics, antiftingals and antiseptics, and laxatives. Others include suntan products, ophthalmic solutions, hemorrhoidal products, sleep aids, and dermatological products for treatment of acne, dandmff, insect parasites, bums, dry skin, warts, and foot care products (11). More recent prescription-to-OTC switches have included hydrocortisone, antihistamine and decongestant products, antiftingal agents, and, as of 1995, several histamine H2-receptor antagonists. 

Sahcyhc acid USP, EP, and other pharmacopeia grades are used medically as antiseptic, disinfectant, antifungal, and keratolytic agents. Sahcyhc acid is formulated in lotion or ointment formulations for the treatment of dandmff, eczema, psoriasis, and various parasitic skin diseases. Because the keratolytic property of this aromatic acid has use in the safe removal of dead skin cells from the surface of healthy skin, the acid is used in concentrated sahcyhc acid solutions or suspensions to remove warts and corns. In more dilute form, sahcyhc acid preparations have found use in dandmff and eczema treatment. Sahcyhc acid has been considered and found effective by the Advisory Committees to the FDA in various over-the-counter (OTC) dmg regulated uses. Among these are acne products, dermatitis, dry skin, dandmff and psoriasis products, and foot care products (24). 

There are hundreds of topical steroid preparations that are available for the treatment of skin diseases. In addition to their aforementioned antiinflammatory effects, topical steroids also exert their effects by vasoconstriction of the capillaries in the superficial dermis and by reduction of cellular mitosis and cell proliferation especially in the basal cell layer of the skin. In addition to the aforementioned systemic side effects, topical steroids can have adverse local effects. Chronic treatment with topical corticosteroids may increase the risk of bacterial and fungal infections. A combination steroid and antibacterial agent can be used to combat this problem. Additional local side effects that can be caused by extended use of topical steroids are epidermal atrophy, acne, glaucoma and cataracts (thus the weakest concentrations should be used in and around the eyes), pigmentation problems, hypertrichosis, allergic contact dermatitis, perioral dermatitis, and granuloma gluteale infantum (251). 

Chemical Acne Many chemical compounds induce skin lesions that are similar to acne. Oils, tar, creosote, and several cosmetic products induce chemical acne. These compounds induce keratinization of the sebaceous glands of the skin, obstruction of the glands, and formation of acne. Chloracne is a specific skin lesion that is induced by chemical compounds that are structurally similar to 2,5,7,8-tet-rachloro dibenzo-p-dioxin (TCDD). Chloracne is slow to heal and difficult to... 

As you can judge from Table A, transition metal cations are frequently found in enzymes. The Zn2+ ion alone is known to be a component of at least 70 different enzymes. One of these, referred to as "alcohol dehydrogenase," is concentrated in the liver, where it acts to break down alcohols. Another zinc-containing enzyme is involved in the normal functioning of oil glands in the skin, which accounts for the use of Zn2+ compounds in the treatment of acne. 

Topical antibiotics exert a direct local effect on specific microorganisms and may be bactericidal or bacteriostatic. Bacitracin (Baciguent) inhibits the cell wall synthesis. Bacitracin, gentamicin (G-myticin), erythromycin (Emgel), and neomycin are examples of topical antibiotics. These drugp are used to prevent superficial infections in minor cuts, wounds, skin abrasions, and minor burns. Erythromycin is also indicated for treatment of acne vulgaris.

Acne medicines may contain ingredients such as salicylic acid, benzoyl peroxide, and sulfur, which remove the top layer of dead skin. They may also contain ingredients that have antibacterial action. Some ingredients reduce sebum production others reduce inflammation. 

Benzoyl peroxide can help remove dead skin cells, which in turn prevents the pores from clogging up. It also kills the Propionibac-terium acnes bacterium that causes acne. It has anti-inflammatory effects and reduces oxygen free radicals and fatty acids on the skin. 

Salicylic acid is used to treat acne, warts, dandruff, psoriasis, and similar conditions. In the treatment of acne, it slows the shedding of skin cells in hair follicles, so they do not clog the pores and cause pimples. It also has a keratolytic effect—it causes dead skin cells to slough off— which removes the top layer of skin and clears existing pore clogs. 

Camphor is used in acne medications, cough remedies, ear drops, and other medications where its ability to soothe the skin helps it to counter the effects of other ingredients that might otherwise be irritants.
