Common Questions

How does glutathione target dark spots in this serum?

Glutathione acts as a master antioxidant that blocks melanin synthesis, neutralising cellular triggers to fade existing hyperpigmentation at its root.

Can I use this serum if I have sensitive skin?

Yes, the formula integrates soothing ceramides and panthenol to buffer active ingredients, ensuring effective brightening without triggering reactivity.

How long does it take to see visible results?

Consistent daily application typically yields noticeable improvements in skin clarity and dark spot fading within two to four weeks.

Can I wear this serum underneath makeup?

The lightweight, fast-absorbing texture dries down completely, creating a smooth, non-sticky base that layers seamlessly beneath cosmetics.

Does this product help with old acne scars?

The combination of Vitamin C, niacinamide, and glutathione actively breaks down residual post-inflammatory hyperpigmentation left behind by blemishes.

Should I use this in the morning or evening?

It is suitable for both morning and evening routines; pair it with sunscreen during the day to protect your progress against UV-induced darkening.
