Ingredients higher up in an ingredient list are typically present in a larger amount. 1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. It is a: Humectant, drawing moisture into the skin Emollient, helping to soften skin Solvent, dispersing and stabilizing formulas Preservative booster, enhancing the antimicrobial activity of other preservatives We don't have a description for 1-Methylhydantoin-2-Imide yet. Acetyl Dipeptide-1 Cetyl Ester is a peptide composed of amino acids arginine and tyrosine. This peptide is considered a neurotransmitter peptide, meaning it has pain-relieving and relaxing properties. It has the ability to calm skin irritation from external factors such as chemical stinging or heat. Neurotransmitter peptides are also often called "botox in a bottle". This is because these peptides have the ability to relax the muscles. Though relaxing the muscles can prevent expression lines (as we have seen in botox), the studies do not show these peptides to be a botox replacement. The effects of this muscle relaxation is also short-term, as opposed to longer-term results from botox. 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. Acetyl Octapeptide-3 is a synthetic peptide also commonly known as SNAP-8. It is a lab-made peptide often marketed as a gentler, topical alternative to Botox. It works by mimicking part of a protein involved in muscle contractions, which may help relax facial tension and reduce the appearance of fine lines (mostly around the eyes and forehead). It’s considered a “next-gen” version of Argireline (Acetyl Hexapeptide-8), an older pept
