Frequently Asked Questions

Q: What does the Double Glutathione Serum do for dark spots?

A: The Double Glutathione Serum uses two forms of glutathione combined with niacinamide and retinol to inhibit melanin production, fade existing dark spots, and prevent new pigmentation from forming — revealing a clearer, more even complexion over time.

Q: Is this brightening serum suitable for sensitive skin?

A: Yes. The Hoygi Double Glutathione Serum is formulated with a mild, non-irritating formula that contains no high-concern chemicals, making it suitable for all skin types including sensitive skin. If you have particularly reactive skin, we recommend doing a patch test before full application.

Q: Can I use this glutathione serum both day and night?

A: Absolutely. The serum is designed for day and night use. Its lightweight, fast-absorbing texture means it layers comfortably under moisturiser and SPF in the morning, or works as a nourishing overnight treatment when used in the evening.

Q: How long does one bottle of the 100ml serum last?

A: With regular twice-daily use of 2–3 drops per application, a 100ml bottle typically lasts 2–3 months. The 3-year shelf life means you can stock up without worrying about the product expiring.
