Science
Mechanism of Action
Glucose functions primarily as a natural humectant, efficiently attracting and binding water to the skin, thereby ensuring deep hydration and preventing dryness for a soft and luminous complexion. It actively promotes skin regeneration by enhancing cellular energy metabolism, accelerating skin cell turnover for a healthier surface. By inducing the expression of key skin barrier proteins like claudin-1 and filaggrin, glucose reinforces the skin's protective barrier, reducing sensitivity and improving overall integrity. It also supports a balanced skin microbiome as a prebiotic, safeguarding against detrimental bacteria. Furthermore, glucose can offer mild exfoliation by weakening the bonds between dead skin cells, and when converted into lactic acid by skin cells or microbiota, it functions as an AHA, contributing to exfoliation and indirectly inhibiting tyrosinase, which leads to reduced melanin synthesis and a skin brightening effect. Plant-based glucose can additionally energize skin cells, bolster resilience against environmental stressors, and stimulate the production of vital structural proteins such as collagen and hyaluronic acid.

Key findings
- 01 Topical glucose, applied at high concentrations, improved Atopic Dermatitis-like skin lesions in a mouse model, exhibiting anti-inflammatory activities and inducing the expression of skin barrier-associated proteins claudin-1 and filaggrin.
- 02 In cultured human skin keratinocytes, high concentrations of glucose successfully restored reduced filaggrin expression induced by cytokines.
- 03 Glucose significantly reduced melanin content in α-melanocyte-stimulating hormone (MSH)-stimulated B16 cells and darkly pigmented normal human melanocytes without cytotoxicity. Topical treatment also demonstrated whitening efficacy in a pigmented 3D human skin model.

Dusting Analysis
Glucose is widely utilized across numerous cosmetic and skincare product categories, reflecting its well-established safety profile and diverse benefits, making it an unlikely candidate for 'dusting' at low, ineffective concentrations.

Conflicts
- There is a theoretical, though debated, concern about topical glucose causing glycation.
- For individuals with diabetes, topical glucose might affect insulin levels in the skin, potentially leading to rare cases of skin cell abnormality.
Safety
Safety Profile
The CIR Expert Panel concluded that glucose and other monosaccharides/disaccharides are safe for cosmetic use, focusing on dermal toxicity as oral safety is established. Glucose is permitted by the FDA as a food sweetener and has no further testing requirements from the EPA under the High Production Volume (HPV) Challenge Program. It may be used in cosmetics in Europe according to general provisions, implying no specific restrictions.
