Perfect for those with experience using active ingredients and suffer from dark marks and blemishes caused by post-inflammatory hyperpigmentation. SAY GOODBYE TO DARK MARKS WITH YEARN SKIN.

Studies have shown that glutathione can help to reduce the production of melanin, which can lead to a more even skin tone and reduce the appearance of dark spots and hyperpigmentation

Niacinamide (Vitamin B3): Known for its multifaceted benefits, Niacinamide works diligently to improve the skin's barrier function, enhancing its ability to retain moisture and protect against environmental stressors. This key ingredient also helps reduce the appearance of enlarged pores and uneven skin tone, leaving you with a smoother and more refined complexion.

Kojic Acid: Derived from natural sources, Kojic Acid is a powerhouse when it comes to brightening the skin. It effectively diminishes the appearance of dark marks, blemishes, and age spots, promoting a radiant and youthful glow. Say goodbye to uneven skin tone as Kojic Acid works its magic.

Alpha Arbutin: Recognised for its skin-brightening properties, Alpha Arbutin gently fades the look of sunspots and hyperpigmentation, promoting a more uniform skin tone. Its potent yet gentle nature makes it an ideal addition to your skincare regimen, ensuring a luminous and balanced complexion.

Experience the confidence that comes with a revitalised, radiant complexion. Make our Glutathione Dark Mark Serum your trusted ally on your journey to healthier, more luminous skin. Unveil your inner glow and face the world with renewed self-assurance.
