Science
Mechanism of Action
Glycolipids operate on multiple levels to fortify skin health. They function as emollients, softening the skin and establishing a protective barrier against moisture loss. These compounds actively enhance skin hydrology by facilitating the circulation of water-based ingredients, strengthening the skin barrier, and improving moisture retention, while also aiding in the formation and maintenance of Natural Moisturizing Factors (NMF). As amphiphilic biosurfactants, they effectively reduce surface tension, enabling the harmonious dispersion of oils and water in formulations, thereby improving product stability and texture. This action also allows for mild cleansing by gently breaking down oils and impurities without compromising the skin's natural lipid barrier. Furthermore, glycolipids boost the spreadability, solubilization, and bioavailability of other ingredients, ensuring optimal absorption. Emerging research indicates potential anti-inflammatory, antioxidant, and regenerative benefits, alongside supporting the skin's naturally acidic pH.

Key findings
- 01 A specific glycolipid blend, utilized synergistically with 1% colloidal oatmeal and 2% salicylic acid, significantly alleviated the itch, irritation, and soreness associated with eczema and psoriasis in over 91% of study participants.
- 02 An in-vivo study involving 20 participants demonstrated a statistically significant reduction in skin sebum values after four weeks of using RHEANCE® One glycolipid, without inducing skin irritation.
- 03 Clinical evaluations revealed that a BioRenuva SL-A70 glycolipid reduced transepidermal water loss (TEWL) by up to 20%, correlating with enhanced epidermal hydration and improved barrier integrity.

Formulation
Stability
As amphiphilic molecules, glycolipids function as effective biosurfactants and emulsifiers, supporting the stability and texture of formulations. They are optimally stable and effective in pH-balanced formulations, ideally within a range of 4 to 7. Precise purity and characterization of specific glycolipid congeners are critical to avoid potential toxicity or interference with their bioactivities within a product.

- Salicylic acid (for eczema and psoriasis relief)
Safety
Safety Profile
Glycolipids are generally considered safe for topical application in cosmetics, presenting a low potential for skin irritation and sensitization due to their natural compatibility with the skin’s lipid barrier. Dermatological studies have consistently shown them to be well-tolerated, even by sensitive skin types. While the FDA has granted GRAS (Generally Recognized As Safe) status for certain glycolipids in food applications, this does not directly pertain to their cosmetic safety status. A broad safety opinion on 'Glycolipids' as an ingredient class has not been issued by the SCCS.
