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. Mandelic Acid is an alpha hydroxy acid (AHA). Like other AHAs, it helps exfoliate the surface of the skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath. Mandelic acid helps with: Due to it having a larger molecular size than glycolic acid, mandelic acid is able to penetrate the skin more slowly and evenly. This makes it gentler and less irritating, making it a great option for sensitive or beginner skin. Despite being milder, mandelic acid is still an effective exfoliant that improves skin texture and tone over time. What makes mandelic acid stand out from other AHAs? It has antibacterial and antioxidant properties. These traits make it a great option for acne-prone or problem skin by reducing active breakouts and fading post-acne marks. Studies show that mandelic acid (especially when combined with salicylic acid) can significantly reduce pimples and hyperpigmentation while causing fewer side effects than stronger acids. Mandelic acid is effective in concentrations of 5% and up with an ideal pH range of 3-4 for at-home use. Like other AHAs, it’s important to wear sunscreen daily to protect your newly exfoliated skin. However, unlike glycolic acid, mandelic acid is light-sensitive. Be sure your mandelic acid is packaged in opaque containers to ensure it stays stable and effective. In short, mandelic acid is a gentle yet powerful AHA that exfoliates, brightens, and helps clarify skin while keeping irritation low. Its antibacterial action makes it especially beneficial for those with acne-prone, sensitive, or uneven skin, offering smoother, clearer, and more even-toned results over time.

This disruption helps the primary preservative system in a product work more effectively at lower doses. On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations. Typical use levels in a formula run about 1-5%. Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective. In small amounts, sodium hydroxide is considered safe to use. However, large amounts may
