Function

ANTI-SEBORRHEIC: Preventing or relieving the symptoms of seborrhea and/or seborrheic dermatitis, including dandruff.
ANTIMICROBIAL: Preventing and/or slowing down microbial growth.
SKIN CONDITIONING - EMOLLIENT: Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.
SKIN PROTECTING: Helping to avoid harmful effects to the skin from external factors.
SKIN CONDITIONING - HUMECTANT: Increasing the water content of the top layers of the skin. Humectants are primarily hygroscopic agents drawing moisture from the surrounding air.
SKIN CONDITIONING - MISCELLANEOUS: Enhancing the appearance of dry and/or damaged skin by reducing flaking and restoring suppleness.
SKIN CONDITIONING - OCCLUSIVE: Retarding the evaporation of water from the skin surface. Occlusives are generally lipids which tend to remain on the skin surface and thus increase the water content of skin.
