Frequently Asked Questions

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

A: The serum's double-dose of glutathione inhibits melanin production, which is the primary cause of dark spots and hyperpigmentation. With regular use, it visibly fades dark spots, evens out skin tone, and leaves skin looking clearer and more radiant.

Q: Is this glutathione serum suitable for sensitive skin?

A: Yes! The Hoygi Double Glutathione Serum is formulated with a mild, non-irritating blend designed to suit all skin types, including sensitive skin. It contains no high-concern chemicals and has a lightweight, fast-absorbing texture that won't clog pores.

Q: Can I use this serum both morning and night?

A: Absolutely. The serum is specifically formulated to balance brightening and moisturising benefits, making it ideal for both daytime and evening use. For daytime use, follow with a broad-spectrum SPF to protect your skin and maximise brightening results.

Q: How long before I see results from the glutathione serum?

A: Results vary by individual, but most users begin to notice improvements in skin radiance and a reduction in dark spots with consistent use over 4–6 weeks. For best results, apply daily as part of your regular skincare routine.
