SAL3 soap is an advanced proprietary soap, designed and tested by dermatologists and chemists. Salicylic Acid and Sulfur soap provides keratolytic, antifungal, and antiseptic action. Salicylic Acid alone is mildly anti-pruritic, bacteriastatic and keratolytic. This effect is due to the lowering of pH at the surface of the skin, improving the hydration of the keratin layer. Salicylic Acid and Sulfur in combination are synergistic, and support normal keratin formation. Bar soap is particularly convenient where larger skin areas - like on your face, or your neck, back, or arms, - are involved. Avoids the messiness often associated with lotions, or ointments. Has salicylic acid and sulphur been recommended to you, for topical application? Has your family doctor or dermatologist recommended SAL3 soap because of your seborrheic dermatitis, psoriasis, keratosis pilaris, or body acne on your face, back, buttocks, or neck? Or, you're dealing with the itching and worry caused by dandruff and you need an advanced soap?
