Medical grade is of higher purity and safety standards and is used in medical applications, while cosmetic grade is more focused on function and end-user perception and is used for routine skin care.
Food grade is applied to normal foods and falls under loose regulations, while medical grade oral products need more rigorous drug standards, including drug purity and bioavailability testing.
Molecular weight directly affects skin penetration rate and the mechanism of action.
The fermentation method uses genetically engineered strains (such as Streptococcus) cultured in a sterile environment, with high product purity and no animal-derived risks; the traditional extraction method extracts from tissues such as rooster combs and is prone to residual heterologous proteins. It has now been phased out by the mainstream market.
