Ingredients higher up in an ingredient list are typically present in a larger amount. This peptide is a lab-made "messenger peptide" that differs from other peptides; it's mostly known for nudging skin pigmentation upward rather than smoothing wrinkles like other peptides. It works by mimicing parts of the alpha-melanocyte-stimulating hormone signaling pathway by telling pigment making cells (melanocytes) to make more melanin. Our bodies produce melanin in response to UV so this peptide is marketed for supporting tanning and has also been explored in hypopigmentation contexts like vitiligo. Though there is some human data, it's doesn't have the best "single-ingredient" evidence. For example, an 8 week clinical study in middle-aged Chinese women found using an essence with 0.02% acetyl hexapeptide-1 + retinol improved photoaging related measures. Since it was a combo product, you can't attribute the results to the peptide alone. In vitiligo research a topical cream with acetyl hexapeptide-1 plus other actives was reported to support repigmentation in some areas. Again, this was a combo product so it's not a pure “acetyl hexapeptide-1 did this” conclusion. If you're trying to fade hyperpigmentation like melasma and sun spots, this may not be the ingredient for you. Again, its generally positioned as a pro-pigment / tanning support peptide. Peptides are usually well tolerated but be sure to patch test if you're cautious or have extra sensitive skin. Alanine is an amino acid and is already found in the human body. Our skin uses alanine to build collagen, elastin, and keratin. 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. Betaine is a humectant. Like hyaluronic acid, it helps attract and retain moisture in the skin. It’s known for being gentle and for helping the skin maintain balanced hydratio
