The difference between Ceramide NP and Ceramide AP

Ceramide is one of the essential components of human skin, a moisturizing factor that supports the intercellular lipid structure between the skin's stratum corneum, binding cells together and linking them with the internal moisture of the skin. There are various types of ceramides on the market, among which the most effective are Ceramide AP and Ceramide NP. These two types of ceramides differ in many aspects:

1. The mechanism of action of Ceramide NP and AP:

Ceramide NP, as an important component of the cell membrane, can replenish lost ceramides, strengthen the intercellular lipid structure, maintain the skin barrier function, and reduce water loss. Ceramide NP also plays a significant role in cell proliferation and differentiation, immune regulation, and other aspects.

Ceramide AP mainly promotes normal desquamation of the skin, prevents peeling, and makes the skin surface smoother. Ceramide AP can also catalyze the degradation reaction of ceramide derivatives, such as citric acid ceramide.

2. The efficacy of Ceramide NP and AP:

Ceramide NP has excellent moisturizing effects, significantly promoting the expression of filaggrin, increasing the water content of the skin, and repairing damaged skin barriers. Ceramide NP is also effective in improving dry, aged skin and sensitive skin conditions, and has certain anti-aging effects, such as stimulating fibroblast proliferation at low concentrations and inhibiting matrix metalloproteinase expression.

Ceramide AP can improve dry and sensitive skin conditions, is used to treat acne, seborrheic dermatitis, and other diseases, and has antioxidant properties, protecting against free radical damage, slowing skin aging, and protecting the skin from environmental stress damage.
