α-Melanocyte-Stimulating Hormone (α-MSH) is an endogenous 13-amino acid neuropeptide derived from pro-opiomelanocortin (POMC). Its function goes far beyond the simple pigment-regulating role implied by its name. As a widespread signaling molecule in the central nervous system, α-MSH exerts its top-level appetite suppression regulatory role by activating melanocortin receptors (especially MC3R and MC4R) expressed in specific neuronal populations. It is a key downstream effector of the leptin signaling pathway and can strongly reduce food intake and increase energy expenditure. In the field of inflammation, it demonstrates powerful systemic anti-inflammatory and immune regulatory activities by significantly inhibiting pro-inflammatory signaling pathways such as NF-κB, and is regarded as an endogenous "brake" molecule for inflammation. Additionally, it is deeply involved in sexual function regulation, learning and memory consolidation, and neuroprotection processes. In recent years, synthetic analogues (such as brevonamine peptide) have been developed for the treatment of the bulimic behavior in the rare disease Prader-Willi syndrome, and their therapeutic potential in traumatic brain injury, psoriasis, and even depression has been explored, highlighting the significant value from basic physiology to clinical translation.

ALPHA melanocyte stimulating hormone (11-13) acetate, as an active fragment of melanocyte stimulating hormone (α - MSH), has shown extensive potential in beauty and skincare, medical research, drug development, and other potential application fields due to its unique chemical structure and biological activity.
Application in the field of beauty and skincare
α-MSH activates adenylate cyclase (AC) by binding to the MC1R receptor on melanocytes, leading to an increase in intracellular cAMP levels, which in turn activates tyrosinase through PKA and promotes melanin production. ALPHA melanocyte stimulating hormone (11-13) acetate retains this core function, and its chemical stability and solubility are improved through acetate modification, making its application in the field of beauty and skincare more extensive.
Safe tanning products: Traditional tanning methods rely on ultraviolet radiation, which may lead to the risk of photoaging and skin cancer. ALPHA - melanocyte stimulating hormone (11-13) acetate can promote melanin synthesis, achieve natural tanning effects, and avoid UV damage. This kind of product usually exists in the form of cream or lotion. Users can apply it evenly on the skin surface to achieve the ideal tanning effect through regular use.
Dosage control: Due to the possibility of excessive skin pigmentation and adverse reactions caused by overuse, strict control of dosage and usage methods is necessary. It is recommended to adjust the frequency and concentration of use according to individual skin type and needs under professional guidance.

Frequently Asked Questions
What is MSH in skincare?
+
-
Melanocyte Stimulating Hormone (MSH)
MSH regulates melanin levels in the skin, hair and eyes (pigments and skin tone). It also regulates protection in the skin against UV rays. MSH is produced from the same starting molecule as ACTH (see adrenal insufficiency).
How does alpha-MSH affect appetite?
+
-
In the central nervous system, α-MSH is cleaved from proopiomelanocortin and then released into different hypothalamic regions to act on melanocortin 3/4 receptor-expressing neurons, lowering food intake, and raising energy expenditure via appetite suppression and sympathetic nervous system.
Is alpha-MSH the same as MSH?
+
-
The melanocyte-stimulating hormones, known collectively as MSH, also known as melanotropins or intermedins, are a family of peptide hormones and neuropeptides consisting of α-melanocyte-stimulating hormone (α-MSH), β-melanocyte-stimulating hormone (β-MSH), and γ-melanocyte-stimulating hormone (γ-MSH) that are produced.
What are the benefits of alpha-MSH?
+
-
In addition to its effects on melanocytes, α-MSH has potent anti-inflammatory effects when administered systemically or locally. The anti-inflammatory effects of α-MSH are mediated by direct effects on cells of the immune system as well as indirectly by affecting the function of resident non-immune cells.
How to increase alpha-MSH?
+
-
Sunlight Exposure
Both sunlight to the skin and natural light exposure to the eyes support MSH production in different ways: UV-B rays stimulate skin cells to increase alpha-MSH, which helps regulate inflammation and immunity.
