Good Molecules Discoloration Correcting Serum 30ml

Good Molecules Discoloration Correcting Serum is a lightweight facial treatment developed to improve the appearance of hyperpigmentation, dark spots, post-acne marks and uneven-looking skin tone.

The formula combines 3% cetyl tranexamate mesylate, an advanced tranexamic acid derivative, with 4% niacinamide. Together, they help reduce the visibility of existing discolouration while supporting a brighter, clearer and more even-looking complexion. Glycerin and propanediol add lightweight hydration without making the serum feel heavy.

Good Molecules Discoloration Correcting Serum is suitable for all skin types and can be used every morning and evening before moisturiser, facial oils and sunscreen.

Best for

Ideal if you want:

• A targeted serum for hyperpigmentation
• Help fading the appearance of dark spots
• A treatment for post-acne marks
• Support for sun-related discolouration
• A more even-looking skin tone
• A serum containing niacinamide and tranexamic acid technology
• A fragrance-free treatment suitable for daily use

Consider another option if: you want an exfoliating treatment for congested pores or built-up dead skin cells. This serum does not contain AHA, BHA or PHA exfoliating acids. Persistent or changing areas of pigmentation should also be assessed by a qualified healthcare professional rather than treated solely with cosmetics.

Key ingredients

3% cetyl tranexamate mesylate
An oil-soluble tranexamic acid derivative that helps improve the appearance of dark spots, post-acne marks and uneven pigmentation.

4% niacinamide
Vitamin B3 helps improve uneven-looking tone, dullness, texture and the appearance of enlarged pores.

Glycerin
A humectant that attracts moisture and supports a softer, more hydrated skin feel.

Propanediol
Helps maintain hydration while supporting the serum’s lightweight, easy-to-layer texture.

Melas approved because…

It combines two well-matched pigmentation-focused ingredients at clearly disclosed concentrations.

The 3% cetyl tranexamate mesylate targets visible discolouration, while 4% niacinamide supports brighter, more even-looking skin and improved texture.

The simple formula does not rely on exfoliating acids, making it easier to introduce into routines that already contain retinoids, vitamin C or occasional exfoliation.

Its fragrance-free, lightweight texture also makes it a practical morning and evening treatment for persistent dark spots and post-acne marks.
