Data indicates this is a traditional professional-grade salve designed to facilitate the conditioning of the skin surface. While it lacks modern chemical exfoliants, its occlusive base and botanical resins provide a localized softening effect on the keratin layer to relieve surface tension.
The formula utilizes a blend of Ichthammol, Arnica, and Calendula. Ichthammol serves as an emollient that softens the skin surface. PRID uses a heavy lipid base to condition the skin area. The product is highly viscous; for maximum surface conditioning, it is suggested to apply a thick layer. For chronic maintenance, users often transition to targeted enzymatic treatments.
