Skin Care

Key takeaways

• Skin Care ranges from mild creams (hydrocortisone, benzoyl peroxide) to prescription oral retinoids (isotretinoin, acitretin) and targeted eczema/psoriasis treatments.
• Mechanism, not just ingredient, separates them: corticosteroids calm inflammation, retinoids and vitamin-D analogs change cell turnover, and antibiotics/antifungals clear infection.
• Number one rule: isotretinoin and acitretin cause severe birth defects; anyone who can become pregnant needs effective contraception during treatment, and with acitretin, for years after.

How these treatments work

Corticosteroids and calcineurin inhibitors calm the immune signals behind redness and inflammation. Retinoids and vitamin-D analogs speed up cell turnover to unclog pores and reduce scaling, while antibiotics and antifungals clear the infection itself.

Choosing between isotretinoin, acitretin and other skin treatments

• Isotretinoin: oral retinoid for severe, scarring acne; shrinks oil glands and normalizes cell turnover over months. Boxed warning: causes severe birth defects, so anyone who can become pregnant needs two contraceptive methods and regular pregnancy testing throughout treatment.
• Acitretin: oral retinoid for severe psoriasis, teratogenic like isotretinoin but longer-lasting. Alcohol converts it into a longer-lived compound, so avoid alcohol during and for two months after treatment, and avoid pregnancy for at least 3 years after the last dose.
• Tretinoin and adapalene: topical retinoids for acne; speed cell shedding to clear pores, cause dryness and sun sensitivity, and need 8 to 12 weeks for full effect.
• Benzoyl peroxide: no oral-retinoid restrictions; kills acne-linked bacteria and lowers antibiotic-resistance risk, but can bleach fabric and hair.
• Corticosteroid creams (clobetasol, betamethasone, fluticasone, triamcinolone, mometasone, hydrocortisone, fluocinolone, desonide, halobetasol): reduce inflammation and itching; the strongest are limited to short courses to avoid thinning skin.
• Tacrolimus and pimecrolimus: non-steroid eczema options that calm immune activity without thinning skin, often used on the face.
• Doxycycline and minocycline: low-dose oral antibiotics for acne/rosacea, used for months for their anti-inflammatory effect; increase sun sensitivity.
• Clotrimazole, miconazole, luliconazole and fenticonazole: topical antifungals for ringworm, athlete's foot, and skin yeast infections.
• Calcipotriene and calcipotriol: vitamin D creams that slow overactive cell growth in psoriasis.
• Fluorouracil, imiquimod and diclofenac gel: treat actinic keratosis (precancerous sun damage) by triggering the immune system to clear it.

Remaining treatments by purpose: tazarotene and azelaic acid for acne/rosacea redness; permethrin and crotamiton for scabies and mites; fusidic acid for impetigo; acyclovir for cold sores and shingles; hydroquinone for pigmented patches; eflornithine for unwanted facial hair; benzocaine, choline salicylate and lignocaine numb skin; zinc acetate and zinc sulfate soothe damaged skin; methoxsalen aids UV therapy for psoriasis/vitiligo; podophyllum resin removes genital warts; heparin, allantoin, cepae extract and silicone gel aid scar healing; dapsone gel eases acne inflammation.

Common questions

Why do isotretinoin and acitretin need pregnancy prevention programs?

Both cause severe birth defects if taken during pregnancy, even briefly, so prescribers require contraception and pregnancy testing throughout treatment. Acitretin's requirement extends 3 years past the last dose, since alcohol can convert it into a longer-lived compound.

Can I use these long-term?

Mild options like hydrocortisone or benzoyl peroxide suit ongoing use, but potent steroids, oral retinoids, and long antibiotic courses are usually time-limited to control specific risks.

Safety essentials

• Isotretinoin and acitretin are contraindicated in pregnancy and need confirmed contraception and pregnancy testing throughout treatment; acitretin also needs alcohol avoidance and contraception continued 3 years after stopping.
• Long courses of potent topical corticosteroids can thin skin; use only as long as your prescriber sets.
• Oral antibiotics and retinoids increase sun sensitivity; use sun protection during treatment.
• Seek care promptly for a severe reaction: widespread rash, blistering, or facial/throat swelling.
