To enhance dermal and transdermal absorption of skincare products, sophisticated solutions are often required. The permeability of skincare ingredients is generally limited by the protective barrier of the stratum corneum, provided that this barrier is intact and healthy.
For effective skincare and to maintain homeostasis, it is essential to support not just the surface sebum layer but also the entire epidermis, including the basal layer where new cells are generated.
Historically, liposomes have been the most effective method for delivering active agents to the skin, significantly advancing skin therapy and achieving measurable, remarkable results. Dr. Baumann’s multilayer liposomes, as well as other liposomes, can encapsulate a variety of ingredients such as vitamins, fatty acids, hyaluronic acid, urea, ceramides, and other essential nutrients, delivering them to the cells and intercellular spaces within the epidermis. Some specialized liposomes can even deliver substances into the bloodstream, but this is for medical use only.
Permeability enhancers like lecithin and glycerol can increase the skin's permeability to topically applied ingredients. A single liposome is known as unilamellar (single layer), while those with multiple layers are referred to as multilamellar. Dr. Baumann’s liposomes are multilamellar, with up to 12 layers, designed to replicate the natural phospholipids in the skin’s cell membranes, intercellular substance, and cell content. These phospholipids are primarily composed of lecithin, a key component of biological membranes.
Liposomes can store both water-soluble and oily substances. Their cosmetic benefits—such as repair, storage, and delivery—make them valuable in dermatology. When applied to the skin, liposomes merge with cellular membranes, providing a prolonged delivery system. Their contents can be retained within intercellular spaces and cell membranes.
Dr. Baumann’s multilayer liposomes also address specific skin issues such as psoriasis, acne, hyperpigmentation, extreme dehydration, sensitivity, and are crucial for anti-ageing treatments. These multilayer structures encapsulate one liposome within another, with each successive  structure (liposomal)becoming smaller to facilitate deeper penetration into the epidermis. Smaller liposomes penetrate deeper into the epidermis.
Each liposome’s aqueous core attracts and contains water-based elements like hyaluronic acid, urea, and vitamins C and B3 (Niacin). The two fatty tails of the liposomes contain fatty acids, which in Dr. Baumann’s and Beau Caire products are derived from vegetable oils. In SkinIdent, fatty acids are biotechnologically created in the laboratory but sourced from plants. These multilayer liposomes are used to deliver skin-identical and compatible ingredients throughout the epidermis to support, protect, and repair the skin’s structures and maintain cell health at every epidermal layer.
Note: These liposomes should only be used with Dr. Baumann SkinIdent products, as combining them with other products may introduce undesirable or ineffective ingredients into the skin.
