Melanogenesis
The biological process by which your skin produces melanin, the pigment that gives skin, hair, and eyes their colour.
Melanogenesis is the multi-step process your skin uses to produce melanin, the natural pigment responsible for skin colour. It takes place inside specialised cells called melanocytes, where an enzyme called tyrosinase converts the amino acid tyrosine into melanin. This pigment is then packaged and distributed to surrounding skin cells. It's a normal, ongoing process that ramps up in response to UV exposure, hormonal shifts, inflammation, or injury.
In skincare, understanding melanogenesis matters because many brightening and tone-evening products are formulated to modulate specific steps in this pathway. Ingredients like vitamin C, niacinamide, arbutin, and tranexamic acid each work at different points: some inhibit tyrosinase activity, others interrupt the transfer of pigment to skin cells, and some act as antioxidants that help limit some of the oxidative triggers linked to uneven pigment. You'll often find these ingredients combined in serums and treatments designed to support a more even-looking complexion over time.
If you're noticing uneven tone or areas of hyperpigmentation, products targeting melanogenesis can be a thoughtful addition to your routine. Pair them with a broad-spectrum SPF 50+ sunscreen daily, since UV is the single biggest driver of excess pigment production. Consistent use over weeks to months is realistic; pigment changes are gradual, so patience genuinely pays off here.
It's worth being honest about limits. Melanogenesis is a deeply embedded biological process, and topical products can only influence it to a degree. Deeper or hormonally driven pigmentation may not respond fully to over-the-counter options alone. If your pigmentation is persistent, changing rapidly, or causing you concern, consider speaking to a dermatologist or skincare professional who can assess whether prescription-level support is appropriate for your skin.
