How does melanotan induce tanning?

Melanotan induces tanning by simulating the action of the naturally occurring hormone alpha-melanocyte-stimulating hormone (α-MSH), which stimulates melanocytes in the skin to produce more melanin. This increased melanin production leads to a darker skin tone, providing a protective response against UV radiation. Additionally, it may enhance the skin's ability to tan when exposed to sunlight, reducing the risk of sunburn. However, it's important to note that the safety and efficacy of Melanotan are not fully established, and its use is associated with potential side effects.
