Ingredients higher up in an ingredient list are typically present in a larger amount. 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. Camellia Sinensis Leaf Extract (tea extract) is one of the most well-researched plant extracts in skincare with an impressive resume. Black tea, green tea, and oolong tea are all harvested from the Camellia Sinensis plant. Studies show green tea extract and its catechins (like epigallocatechin gallate (EGCG)) help your skin cells product energy more efficiently and reducing the number of free-radicals that can damage your skin from the inside. In lab-grown skin models, this translated to younger, healthier, and stronger skin. There's also good sun protection data; researchers saw less DNA damage and redness on human skin when green tea was applied before UVB exposure. And the more they applied, the better the protection. Needless to say, this ingredient shouldn't replace your sunscreen. But it is a great supportive ingredient that you can already find in many sunscreens and antioxidant serums. A 2009 study found a 2% green tea lotion was effective for mild-to-moderate acne thanks to its anti-inflammatory and mild antimicrobial activity. The quality of the extract matters a lot here: Good extracts contain 50-90% catechins while lower quality ones are mostly there for marketing. We recommend reaching out to the brand if you have questions about the quality or source of their ingredients. Human Repeated Insult Patch Testing showed no irritation or sensitization at use concentrations (0.86% in leave-on products and up to 30% as leaf water). Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that: The CIR Expert Panel found mini
