Its unique properties, including antioxidant effects, detoxification, and promotion of cellular repair, have demonstrated significant benefits for improving skin condition and enhancing overall health. Let’s delve into the functions of reduced glutathione and its advantages for the skin.

What is Reduced Glutathione?

Reduced glutathione is a tripeptide compound composed of three amino acids: glutamic acid, cysteine, and glycine, linked by peptide bonds. This unique chemical structure endows it with various biological activities, particularly excelling in antioxidant, detoxification, and immune regulation functions.

In the body, reduced glutathione exists in two forms: the reduced form (GSH) and the oxidized form (GSSG), with the reduced form being its active form capable of participating in redox reactions.

Differences Between Reduced Glutathione and Oxidized Glutathione

Reduced glutathione (GSH) and oxidized glutathione (GSSG) are two vital forms present in biological systems, exhibiting significant differences in structure, function, and applications. Both play crucial roles in maintaining cellular homeostasis, participating in redox reactions, and protecting the body from oxidative stress.

Molecular Formula and Molecular Weight

From a structural perspective, the molecular formulas of GSH and GSSG are distinctly different. Reduced glutathione (GSH) has a molecular formula of C10H17N3O6S and a molecular weight of 307.33, constituting approximately 95% of total glutathione. In contrast, oxidized glutathione (GSSG) has a formula of C20H32N6O12S2 and a molecular weight of 612.63, representing about 1% of glutathione in the body. This disparity directly influences their respective functions and mechanisms.

Melting Point and Stability

The melting points of GSH and GSSG also vary. GSH melts within the range of 189 to 193°C, indicating stability at higher temperatures but undergoing decomposition at its melting point. GSSG has a lower melting point of 178°C and similarly decomposes upon reaching this temperature. These differences reflect variations in stability and reactivity in biological systems.

Biological Functions and Applications

(1) Reduced Glutathione (GSH)

GSH is one of the most important intracellular antioxidants, participating in various redox reactions through its thiol (-SH) group, combating damage from free radicals and peroxides. It is particularly abundant in the liver and effective against various liver diseases, including alcoholic and drug-induced liver damage, as well as chronic hepatitis B and C. GSH not only alleviates symptoms but also promotes liver function recovery.

Moreover, GSH is widely utilized in pharmaceuticals, dietary supplements, health foods, and cosmetics due to its antioxidant and detoxification properties. It plays a crucial role in treating heavy metal poisoning, radiation damage, leukopenia, and radiation-induced bone marrow inflammation. In ophthalmology, GSH eye drops are employed for conditions like early age-related cataracts and corneal ulcers.

(2) Oxidized Glutathione (GSSG)

Although GSSG is present in lower concentrations, its role is significant. It is primarily used as a research tool for enzymatic assays measuring NADP and NADPH, making it an important reagent in biochemical studies. GSSG also participates in redox reactions within cells, albeit with lower activity, requiring specific enzyme-catalyzed reactions to be reduced back to GSH to restore its antioxidant capacity.

The conversion between GSSG and GSH is essential for maintaining cellular redox balance. During oxidative stress, GSSG levels rise, while GSH is regenerated via glutathione reductase to counter oxidative challenges. This process not only protects cells from oxidative damage but also maintains cellular stability.

Plant-based squalane is a high-quality ingredient widely used in cosmetic formulations and can be quickly verified for its plant origin through carbon-13 testing.

Historically, squalene was mainly extracted from shark liver oil and used as a dietary supplement; however, most marine-sourced squalene has been replaced by plant-based squalene, with marine sources now used mainly in the pharmaceutical industry, especially in vaccines.

Synthetic Squalane

Synthetic squalane is produced through two main methods:

One involves petrochemical synthesis using terpene compounds to create high-purity squalane;

The other employs biotechnology, where genetically modified microorganisms ferment sugar molecules to produce squalene, which is then chemically synthesized and dimerized to obtain squalane.

This biotechnological method is more sustainable and reduces reliance on traditional petrochemical processes, offering an environmentally friendly production alternative.

Three Key Benefits of Squalane

Hydration and Moisture Retention

Squalane is one of the oils closest in composition to human sebum, offering excellent oxygen-carrying properties. It integrates seamlessly with the skin’s natural oils, forming a highly permeable protective barrier on the skin’s surface.

This barrier not only prevents moisture loss and nourishes the skin but also ensures that the skin can effectively exchange water and air without feeling greasy.

By maintaining the balance between the skin and its sebum, squalane provides deep hydration and enhances the skin’s ability to absorb moisture and other nutrients.

Regular use can improve various skin issues such as sagging, dryness, flakiness, roughness, and dullness, helping the skin regain its softness.

Anti-Ageing

Squalane boasts impressive antioxidant properties, which contribute to its effectiveness in penetrating the skin, promoting the proliferation of basal skin cells, and inhibiting the oxidation of skin lipids. Since oxidation is a major factor in skin ageing, squalane helps to delay the signs of ageing by combating oxidative damage.
