Ingredients higher up in an ingredient list are typically present in a larger amount. 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. Hyaluronic acid also stabilizes it and boosts its antioxidant activity. Ferulic Acid is a plant based antioxidant that can be naturally found in the cell walls of grains like rice, oats, and corn. It has antioxidant and antimicrobial properties, and has the ability to boost the performance of other antioxidants as well. A well-known study found that adding Ferulic Acid to a solution of Vitamins C and E doubled the photoprotection of skin. This is why you'll often see it paired with Vitamin C or Vitamin E serums rather than sold on its own. A 2025 review of 18 human studies found that using Ferulic Acid (0.5-1%) daily for one to three months showed improvements in: As far as allergies go, Ferulic acid is generally well-tolerated but can cause an allergic reaction in very rare cases. It's also worth noting that Ferulic acid is often extracted from plant sources like rice bran or wheat bran, so be sure to path test if you have known grain allergies. Outside of skincare, researchers are also looking into Ferulic Acid for its potential benefits in areas like diabetes, Alzheimer's, and heart health. Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceo
