Cysteamine & Vitamin C-infused serum to reduce dark spots and enhance skin clarity.

Fades Dark Spots

Infused with micro-encapsulated Cysteamine HCl and Vitamin C, this serum targets stubborn pigmentation and uneven skin tone, breaking down melanin clusters and reducing the appearance of dark spots, melasma, and discoloration. With regular use, skin appears brighter, more even, and naturally radiant, restoring a youthful, luminous glow.

Peptides & Phytic Acid help to block melanin overproduction and prevent pigmentation.

Prevents Pigmentation

With a powerful blend of Peptides, Phytic Acid, and Antioxidants, this serum blocks excess melanin production at the source, preventing new dark spots from forming while gradually fading existing hyperpigmentation. It restores clarity and uniformity to dull, tired skin, maintaining long-term brightness and even tone.

Peptide Complex & Ginkgo Biloba-infused serum for smoother, more resilient skin.

Strengthens Skin Barrier

Formulated with Peptide Complex, Ginkgo Biloba, and Sodium Citrate, this serum not only brightens but also nourishes and fortifies the skin barrier. It reduces redness, smooths rough texture, and enhances skin’s resilience, helping it stay hydrated, balanced, and protected against environmental stressors. The lightweight, non-greasy formula absorbs quickly, leaving skin soft, plump, and refreshed.

Can I use this serum daily?

Yes! This serum is gentle enough for daily use and works best when applied twice daily for optimal brightening and discoloration correction.

Is this serum suitable for sensitive skin?

Yes! The micro-encapsulated Cysteamine HCl and Peptide Complex help minimize irritation while brightening, making it ideal for all skin types.

How long does it take to see visible results?

Most users notice improvements in skin clarity and brightness within 4-6 weeks, with continued improvement over time.
