Good Molecules Daily Brightening Serum 30ml

Good Molecules Daily Brightening Serum is a lightweight facial serum developed to improve the appearance of dark spots, dullness and uneven-looking skin tone while supporting everyday hydration.

The water-based formula contains 3% beta-arbutin, which helps reduce the visibility of excess pigmentation and supports a brighter, more even-looking complexion. Glycerin and hyaluronic acid help attract moisture, leaving the skin feeling smoother and more hydrated without a heavy or greasy finish.

Good Molecules Daily Brightening Serum is suitable for normal, dry, oily, combination and sensitive skin. Its fragrance-free formula can be used every morning and evening before moisturiser, facial oil and sunscreen.
