- Vitamin D Analogues
Vitamin D analogues are synthetic forms of this vitamin. They may be used alone or combined with topical corticosteroids for more effectiveness. They help reduce psoriasis symptoms in the scalp, torso, and limbs. They do this by slowing down the growth of skin cells and reducing inflammation.
Calcitriol and calcipotriene [2] are common types of vitamin D analogues. They are more expensive than topical corticosteroids but they have few side effects. Of the two, calcitriol causes less skin irritation in sensitive body parts.
