Ingredients higher up in an ingredient list are typically present in a larger amount. Beta-Glucan is a soluble polysaccharide (a chain of glucose sugars) sourced from the cells walls of oats, baker's yeast, mushrooms, and seaweed. It's a rare ingredient that pulls double-duty as a heavy-duty hydrator and skin-soothing repair agent. On the surface, it acts as a humectant that holds water in place and reduces moisture loss for a plumper, smoother feel, while its anti-inflammatory and antioxidant properties make it a great pick for calming redness or sensitive skin The more interesting story is underneath: Despite its large molecular size, oat beta-glucan has been shown to penetrate the epidermis and reach the dermis by slipping between skin cells. Here, it interacts with fibroblasts and macrophages to nudge collagen synthesis and support wound repair. A small 2005 split-face clinical study of 27 subjects found topical beta-glucan produced measurable reductions in wrinkle depth, height, and roughness after 8 weeks of use. It is worth noting the trial was small and the penetration testing used frozen, irradiated skin so the anti-aging data is encouraging rather than definitive. This ingredient gets along with pretty much everything and is typically used around 0.1-1%. Fungal acne: This ingredient is not a food source for the Malassezia yeast because it is a glucose polysaccharide with no fatty acid or ester component. Epigallocatechin Gallate (EGCG) is the most abundant catechin in green tea. It is a heavyweight antioxidant in the green tea family. In skincare, it helps protect skin from photoaging damage by scavenging UV-induced reactive oxygen species and tampering down inflammatory pathways. UV-exposed skin cells treated with EGCG showed less of the enzyme that chews up collagen, lower inflammatory signaling, and better preserved barrier function. EGCG nudges skin cells to make more of your skin's built in moisturizing molecules, filaggrin and hyaluronic acid, for better skin hydration. Because it inhibits melanogenesis, it also provides a mild brightening effect. Clinically, topical EGCG has helped calm radiation-related skin irritation and scalp seborrheic dermatitis with no major side effects. In an 8-week split-face study, topical EGCG at 1% and 5% significantly reduced inflammatory and non-inflammatory acne. A study from 2023 on patients with Seborrhea (a chronic skin condition caused by overactive sebaceous glands) found that using a 5% EGCG cream (alone and combined with 2% L-carnitine) and found meaningful sebum reduction plus better hydration. Just one caveat here: Most clinical trials used 1-5% concentrations and most cosmetics contain only 0.1-1%. The only headache related to this ingredient is stability. EGCG degrades quickly with heat, light, oxygen, and higher pH. That's why you'll usually see it in low-pH formulas (4.5-6.5) or paired with vitamin C + vitamin E to slow its degradation. Hy
