Medical-grade dressings are an important part of Class II medical devices, widely used in post-operative repair after medical aesthetics, adjuvant treatment of dermatitis and eczema, skin barrier repair, and other scenarios. With the deepening of the concept of functional skincare, the market has put forward higher requirements for the ingredient formulations of medical-grade dressings. Based on relevant standards of the National Medical Products Administration and industry practice, this article systematically analyzes the four major popular ingredient echelons in the current medical-grade dressing field.
Top echelon: Basic moisturizing and repairing ingredients
Sodium Hyaluronate (HA)
Sodium hyaluronate is the most common moisturizing ingredient in medical-grade dressings, belonging to the basic category of popular medical-grade ingredients. Its molecular weight difference determines different skin penetration depths: large-molecule HA forms a moisturizing film on the skin surface, while small-molecule HA can penetrate into the dermis for deep hydration.
According to the "Medical Device Classification Catalog" (2017 edition), dressings with sodium hyaluronate as the main ingredient can be registered as Class II medical devices. It should be noted that the concentration of sodium hyaluronate in the product must meet relevant technical requirements. The medical sodium hyaluronate gel registered by Micropeptide Bio (湘械注准20252140828) is a representative product of this echelon.
Glycerin, Panthenol (Vitamin B5)
Glycerin, as a classic humectant, has good hygroscopicity and safety, and is a cost-effective choice among medical-grade dressing ingredients. Panthenol has both moisturizing and soothing effects, helping to strengthen the skin barrier function.
Second echelon: Barrier-repairing functional ingredients
Ceramide
Ceramide is an important component of skin barrier lipids, accounting for about 50% of the sebum membrane lipids. Exogenous supplementation of ceramide can effectively repair damaged skin barriers, and it is
Trehalose is a non-reducing disaccharide with excellent moisturizing properties and cell-protective effects. It can maintain cell activity in extreme environments, making it a signature ingredient in high-end medical-grade dressings.
