What medication can completely eradicate psoriasis?

Psoriasis is commonly referred to as “ox skin disease” in traditional Chinese vernacular. Generally speaking, psoriasis cannot be completely cured; however, patients may significantly improve their symptoms under medical guidance using topical medications such as calcipotriol ointment, halometasone cream, tacrolimus ointment, benzoyl peroxide (benvimod) cream, and compound dithranol ointment. A detailed analysis follows:

1. Calcipotriol Ointment

This is a vitamin D3 derivative that regulates the proliferation and differentiation of keratinocytes in the skin, suppresses abnormal cellular metabolism in hyperproliferative skin lesions, and alleviates erythema and scaling. It is primarily used for mild-to-moderate plaque psoriasis and rarely induces drug resistance with long-term use.

2. Halometasone Cream

A potent topical corticosteroid, halometasone effectively suppresses local cutaneous inflammatory responses, reduces capillary dilation, and relieves erythema, induration, and pruritus. It is particularly suitable for thickened, treatment-resistant psoriatic plaques.

3. Tacrolimus Ointment

As a calcineurin inhibitor, tacrolimus blocks the release of pro-inflammatory cytokines and suppresses aberrant cutaneous immune responses. Its gentle formulation promotes repair of damaged skin and is especially appropriate for psoriatic lesions on sensitive areas such as the face and intertriginous regions.

4. Benvimod Cream

This agent modulates cutaneous immune function, inhibits inflammatory cell infiltration and abnormal epidermal hyperproliferation, and improves scaling and erythema. It demonstrates therapeutic efficacy across multiple subtypes of plaque psoriasis and is well-suited for most patients with mild-to-moderate disease.

5. Compound Dithranol Ointment

Containing dithranol and salicylic acid, this ointment inhibits excessive epidermal cell proliferation, softens and facilitates desquamation of thickened scaly plaques, and reduces cutaneous inflammation. It is commonly employed for symptomatic management during the stable phase of plaque psoriasis.

In daily life, maintain skin cleanliness and hydration, minimize dryness and irritation, and avoid scratching or rubbing affected areas. Adhere to regular sleep patterns, maintain emotional stability, avoid staying up late or overexertion, follow a bland diet, and steer clear of spicy or irritating foods—these measures collectively support cutaneous homeostasis.
