For psoriasis, non-hormonal ointments can be chosen, such as vitamin D3 derivatives and calcineurin inhibitors. It is recommended to choose appropriate medications under the guidance of a doctor based on the condition of the skin lesions, and to combine this with basic skincare such as moisturizing.

Specifically, common options include:

1. Vitamin D3 derivative ointments, such as calcipotriol, help regulate skin cell growth and reduce scaling and plaque. They are generally suitable for common plaques on most parts of the body.
2. Calcineurin inhibitors, such as tacrolimus ointment, have anti-inflammatory effects and may be more suitable for areas with thinner or more sensitive skin, such as the face and neck.
3. Some moisturizers or skincare products containing keratin-softening ingredients, while not strictly speaking therapeutic drugs, can help improve symptoms by keeping the skin moisturized and reducing dryness and flaking.
In daily care, avoid scratching or over-cleaning the affected area, and apply moisturizing cream promptly after bathing. If the effect of non-steroidal ointments is not obvious, or if the affected area expands, you should promptly return to your doctor for evaluation to determine if the treatment plan needs to be adjusted.
