Ingredients higher up in an ingredient list are typically present in a larger amount. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. This ingredient is also known as Tsubaki oil, or the fixed oil from the seeds of the Japanese camellia. It's basically a fatty acid delivery system (~75-85% oleic acid) plus some minor extras like squalene, tocopherols, and phytosterols. That profile makes it a classic emollient; it works by hanging out with the skin's surface lipids, softens, and slows down water loss. The most cited study on it was done on skin cells in a dish where this oil got them to make more of the building blocks for collagen while also slowing down the enzyme that breaks collagen down. Researchers tested this on human skin too; it didn't cause irritation and helped skin hold onto moisture better. Another study done on cells and mice found this oil quieted down some of the body's inflammation signals. These studies are still small, early, and not done on humans, so it's best to think of this ingredient as a great supporting ingredient for the rest of your routine and not the main active. Concentrations can range from 1-5% in serums to 100% as a single face oil (how it's most traditionally used). Because this ingredient is a triglyceride of long-chain fatty acids, this ingredient may not be Malassezia safe. Allergies to this protein are quite rare as the refined seed oil contains very little residual protein. Human irritation testing also came back clean. But it is a plant and as with any botanical ingredient, contact allergy is possible. Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes. Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath. However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products. Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH. In skincare formulas, citric acid can: While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants. Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations. Rosacea skin has a lower threshold for acids generally, with 62.5% of rosacea subjects in one study reacting to lac
