Silkis is a topical medication primarily used in the treatment of psoriasis, a chronic skin condition characterized by red, flaky, crusty patches of skin covered with silvery scales. The active ingredient in Silkis is calcitriol, which is a synthetic form of vitamin D3. Calcitriol works by modulating the growth and development of skin cells, helping to reduce the excessive production of skin cells seen in psoriasis. This action helps to alleviate the symptoms associated with the condition, such as itching, scaling, and the thickness of psoriasis plaques. Silkis is available in the form of an ointment and is applied directly to the affected areas of the skin as prescribed by a healthcare professional. It is important for patients to follow their healthcare provider's instructions when using Silkis to ensure its effectiveness and to minimize potential side effects.
