Nonapeptide-1 is a skin lightening peptide, derived from the melanocyte stimulating hormone (MSH). It prevents the activity of tyrosine in the melanocytes, melanin synthesis inhibition and helps to even out your skin tone by lessening hyper-pigmentation. This process reduces the formation of unwanted pigmentation, allowing for the control over skin tone and brown spots.九肽-1是一种皮肤美白肽，源自黑素细胞刺激素（MSH）。它可以防止黑素细胞中酪氨酸的活性，抑制黑素合成，并通过减少色素沉着来帮助平衡肤色。这一过程减少了不必要的色素沉着的形成，允许控制肤色和棕色斑点。
