Ingredients higher up in an ingredient list are typically present in a larger amount. Arginine is a semi-essential amino acid. This just means our bodies can product a bit on its own, but sometimes needs a little boost from food sources. It is a part of your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy. Here's an interesting thing about Arginine: your skin converts it into urea through the Krebs-Henseleit urea cycle. Urea is one of the most effective humectants your skin naturally produces. A clinical study showed applying 2.5% arginine hydrochloride to atopic dermatitis skin showed significant urea levels in the stratum corneum and improved moisture in just four weeks. Arginine is also a precursor to nitric oxide; nitric oxide improves microcirculation and supports wound healing and collagen synthesis. One study found that an amino acid complex containing Arginine reduced skin irritation, improved hydration, and accelerated skin repair in clinical / in-vivo studies. Arginine itself is an amino acid and not a fatty acid, oil, or ester. On its own, it's not a direct food source for Malassezia, or the yeast that causes fungal acne. Biotinoyl Tripeptide-1 is a lab-made molecule that combines two parts: biotin (vitamin B7) and Tripeptide-1. Together, they form a peptide that’s often used in hair and eyelash products. In-vitro studies show this ingredient helps hair bulb cells grow faster and product more structual proteins. This helps keep hair securely anchored in the follicle. A small human study using a mascara with 2% Biotinoyl Tripeptide-1 reported lashes that were about 17% longer and 19% thicker after one month. One study from 2025 compared topical spray vs. a combined tropical/oral treatment. The combination group saw greater increases in total hair count. While these early results are encouraging, most of the data comes from in-vitro experiments (in test tubes) or small, short-term trials. Biotinoyl Tripeptide-1 looks promising for supporting hair strength and growth but there’s not yet strong clinical evidence to confirm how well it works. 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. 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 sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential f
