Ingredients higher up in an ingredient list are typically present in a larger amount. Biotin is a B vitamin that is naturally produced by our bodies. It is also called Vitamin H. Our bodies use biotin in the metabolism process. It also helps our bodies use enzymes and move nutrients around. A biotin deficiency can lead to brittle hair and nails. More research is needed on applying biotin topically. However, taking biotin orally has been shown to help nourish the skin, hair, and nails. They play a role in forming skin-hydrating fatty acids. Biotin is water-soluble. It can be found in foods such as fish, eggs, dairy, nuts, and meat. Vitamin H stands for "haar" and "haut". These are the German words for hair and skin. 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. Myristoyl Pentapeptide-17 is a five amino peptide attached to myristic acid to help it absorb better into skin. It's mostly used for lash growth and as a delivery vehicle for other ingredients. The myristic acid "tail" is basically a delivery upgrade that helps the peptide mix with your skin's natural oils so it can get where it needs to go. In your eyelash follicles, it activates the keratin gene and promotes nutrient absorption into the follicle. This translates to thicker and longer eyelashes over time. Besides stimulating keratin production for lash growth, this ingredient enhances the delivery of other active ingredients in a formula. The clinical evidence is still pretty early-stage at this point. A 90 day study in 29 participants found improvements in lash length (10.52%), volume (9.3%), thickness (35%), and curl (50.83%) with no adverse reactions reported.
