Cycle of pigmentation (how does it happen?)

Stage 1- Before sun exposure: Melanocytes are located in the bottom layer of the epidermis.
Stage 2During sun exposure/ hormonal changes/ trauma such as acne etc: Melanocytes are activated by an enzyme called tyrosinase.
Stage 3- Right after the trauma: The enzyme tyrosinase starts its work to produce melanin.
Stage 4- During melanin synthesis: Tyrosinase goes on a rage to produce more melanin.
Stage 5- After melanin synthesis: Melanin spreads itself through the area to protect the skin from the trauma.
