Your concern about who is suitable to use tanning peptides is commendable, as any choice involving health and appearance changes deserves serious consideration.
The suitable population for tanning peptides needs to be strictly differentiated: Afamelanotide, as a prescription drug, is mainly suitable for patients with erythropoietic protoporphyria (EPP), while over-the-counter tanning ingredients (such as myristoyl tetrapeptide-20 and octapeptide-5) are suitable for the general population who wish to gently improve their skin tone, but both require attention to usage conditions and risks.
Medical Use: Afamelanotide – Patients with specific diseases
Afamelanotide is a synthetic alpha-melanocyte-stimulating hormone (α-MSH) analogue that enhances the skin's tolerance to light by stimulating melanin production. Its primary approved indication is:
Patients with erythropoietic protoporphyria (EPP). These patients lack a specific enzyme, leading to the accumulation of protoporphyrins. Their skin is extremely sensitive to light, and even mild sun exposure can trigger severe pain, redness, and even blisters. Alfanotide, administered subcutaneously (16mg), is slowly released to help the skin produce more melanin, thereby improving its ability to protect against light.
