Tanning injections and Nasal spray refers to products containing Melanotan II, a synthetic peptide that stimulates the body’s own melanin production to create a deep, natural-looking tan with less sun exposure or a more golden glow for those who are exposed to more sun.

Why it’s used is to achieve a tan safely and efficiently, reducing reliance on UV rays, and what it does is produce melanin, leading to a darkened complexion.
