Final answer:
The major indoor tanning lotion type that typically includes tyrosine, an amino acid necessary for the production of melanin in the body, is the one that promotes the stimulation of melanocytes.
Step-by-step explanation:
Among the major indoor tanning lotion types, the formula that typically includes tyrosine, an amino acid necessary for the production of melanin in the body, is the one that promotes the stimulation of melanocytes. Melanocytes are responsible for producing melanin, the pigment that gives color to the skin, hair, and eyes. Tyrosine is a precursor to melanin synthesis and helps to increase the production of melanin in the body.
