4-Butylresorcinol
The primary pigment-targeting active within MELA Serum.
4-Butylresorcinol helps inhibit tyrosinase, an enzyme involved in the production of melanin.
pHformula specifically highlights its molecular structure and skin bioavailability as important to its depigmenting activity.
Rather than simply exfoliating pigment already present at the surface, it helps address the process of excess pigment formation itself.
Tetrapeptide-30
A targeted brightening peptide used to help visibly reduce hyperchromatic spots and improve uneven-looking skin tone.
It complements 4-Butylresorcinol through a different pigmentation-supporting mechanism.
Neuro-light / Pancratium Maritimum Extract
pHformula's Neuro-light technology is derived from Sand Lily, which appears in the ingredient declaration as Pancratium Maritimum Extract.
The brand uses it to help reduce the appearance of hyperpigmentation and support a more even skin tone.
Neuro-light is a branded technology name rather than the INCI ingredient itself.
pH Cell-detox / Hydrolyzed Candida Saitoana Extract
pHformula describes pH Cell-detox as technology designed to support cellular autophagy.
Autophagy is the cell's natural recycling process, through which unnecessary or dysfunctional cellular components are broken down and cleared.
The relevant ingredient in the current formula is Hydrolyzed Candida Saitoana Extract.
Its role is primarily cellular-support and radiance enhancement rather than direct exfoliation.
Low-Molecular-Weight Hyaluronic Acid
Represented in the current INCI by Sodium Hyaluronate.
It helps attract and retain water within the skin, providing lightweight hydration and helping support skin-barrier comfort.
This is particularly useful when MELA Serum is incorporated into a more intensive resurfacing or pigmentation routine.

Use morning and evening.
Cleanse thoroughly with your recommended pHformula cleanser, rinse well and gently pat the skin dry.
If you are using a prescribed pHformula Active Prescription, apply this first.
Then apply a few drops of MELA Serum over the face, neck and décolleté.
Massage gently using light circular movements and allow the serum to absorb fully.
Follow with your recommended eye product and moisturiser.
Every morning, finish with broad-spectrum sunscreen.
