A by-product of bituminous coal refined into topical medicine, it is a keratoplastic agent that normalizes skin cell growth and shedding. Its keratolytic action also softens crusting in eczema and seborrheic dermatitis. The FDA lists coal tar as a Category I ingredient (safest and most effective) for OTC dandruff, seborrhea, and psoriasis. Evidence comes from decades of clinical experience more than large modern trials.
For the full breakdown, see our best Coal Tar Cream For Eczema guide.
When Is Coal Tar Cream Used?
Doctors recommend it for plaque psoriasis on the body, eczema unresponsive to moisturizers alone, and seborrheic dermatitis on scalp, face, or chest. It also appears in shampoos for stubborn dandruff. Forms include cream, ointment, gel, lotion, shampoo, foam, and soap, with concentrations from 1% (shampoos) to 12% (stronger ointments). Creams (1–5%) are best for daytime use on larger areas where absorption matters. Common brands include MG217, Psoriasin, Oxipor VHC, Cutar, and Scytera (2% foam).
Applying Coal Tar Cream Safely
Adults apply a thin layer to affected skin up to four times daily (or per label); stronger pomades/ointments are usually once or twice daily under doctor guidance. Wash hands after use unless treating hands. External use only—avoid eyes, mouth, genitals, broken skin. Trade-offs include a distinct smoky odor and staining of clothing/bedding; many apply at night with old clothes or loose wrap. Common side effects: temporary stinging/burning and increased sun sensitivity—cover treated areas or use sunscreen. Less common: irritation, folliculitis, contact allergy.
| Form | Typical Concentration | Best Use |
|---|---|---|
| Cream / Lotion | 1% – 5% | Daytime use on body and limbs; absorbs fairly well |
| Ointment / Pomade | 5% – 12% | Night treatment for thick plaques on arms, legs, trunk |
| Shampoo / Scalp Solution | 1% – 5% | Scalp psoriasis, seborrheic dermatitis, stubborn dandruff |
| Foam | 2% | Hard-to-reach or hairy areas; dries quickly |
| Gel | 1% – 5% | Facial patches and scalp line (less greasy) |
Mayo Clinic’s coal tar topical overview notes most people tolerate it well, but warns against applying to large areas of broken or infected skin. If no improvement after four weeks of regular use, or if the area becomes redder and more painful, stop and consult a doctor. For mild to moderate cases, coal tar cream remains an affordable, reliable non-prescription tool—match concentration to the condition and stick with it long enough to see results.
FAQs
Can I use coal tar cream on my face?
Yes, with caution—the face is more sensitive. Start with 1–2% cream on affected spots, avoiding eyes, nostrils, mouth. If stinging persists, switch to milder product or limit to body areas.
Does coal tar cream cause skin cancer?
Concerns stem from older occupational studies of industrial coal tar, not modern OTC use. The FDA classifies it as safe and effective. Real risk is increased sun sensitivity—always protect treated skin from UV exposure.
How long until I see results?
Some notice softer, less red skin within days; full improvement typically takes two to four weeks of consistent use. Plaque thickness and scaling respond faster than redness. No change after four weeks may require stronger concentration or different treatment.
