Ingredients higher up in an ingredient list are typically present in a larger amount. 1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. It is a: Humectant, drawing moisture into the skin Emollient, helping to soften skin Solvent, dispersing and stabilizing formulas Preservative booster, enhancing the antimicrobial activity of other preservatives Alpha-Arbutin is a brightening active used to fade dark spots, melasma, and post-acne marks. Structurally, it is a hydroquinone with a sugar molecule attached (but is much gentler than raw hydroquinone). It has a pretty elegant way of working; it slots into tyrosinase, or the key enzyme that your skin uses to make melanin), and competitively blocks it so your skin produces less pigment over time. There are two forms of arbutin and alpha is the better one to reach for: it works at lower amounts, absorbs into skin more easily, and has a strong safety record. The science backs this up too: lab and animal studies confirm it lowers melanin by blocking tyosinase and the more you use (up to a point), the more it works. Human studies look good too. A 2024 trial found a cream with 5% alpha-arbutin and 2% kojic acid worked about as well as a prescription melasma cream but with fewer side effects. Another study showed 2% alpha-arbutin paired with 10% Trihydroxybenzoic Acid Glucoside and sunscreen faded dark spots and melasma without causing irritation. Concentration-wise, most serums land in the 1-2% range. The EU's Scientific Committee on Consumer Safety concluded that alpha-arbutin is safe in face creams up to 2% and body lotions up to 0.5%. Overall, this is a well-studied and low-irritation brightener that's a great pick for anyone dealing with uneven skin tone. It also pairs well with vitamin C, niacinamide, and sunscreen. 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 is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel. It is also an emulsifer, meaning it prevents ingredients such as oil and water from separating. It also helps evenly disperse other ingredients. Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging. And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin. You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this. In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to i
