Traditional soap-based cleansing has strong degreasing capability, has great negative influence on acid-base environment and microecology of skin, and can cause certain irritation.

Amino acid cleansing is weakly acidic or neutral, mild and non-irritating, and has become the mainstream of the market, but the current amino acid cleansing still generally has some problems, such as weak cleaning ability.
