MSM has a softening, deeply penetrating effect on the skin when applied topically. It has the unique ability to penetrate several skin layers and therefore provides a better, more deeply hydrating and smoothing effect for longer periods of time. It is one of the best ingredients to look for if you have chronically dry skin or skin that has lost a lot of its elasticity.
The sulfur compound also has an anti-inflammatory and skin-repairing effect, which may be useful for inflammatory skin conditions such as eczema, acne and psoriasis. It also may help smooth and soften acne scars and hasten the healing of existing lesions.
