Glutathione Glow Serum is a lightweight dropper serum. Medicube makes it for skin that looks dull or uneven in tone, including dark spots. The label lists a glutathione liposome at 5% and niacinamide at 5%.

Key ingredients

• Glutathione: an antioxidant, held here in a liposome, for skin that looks dull.
• Niacinamide: a form of vitamin B3, used for a more even-looking skin tone.
• Adenosine: one of the key ingredients Medicube names for this serum, alongside glutathione and niacinamide.
• Collagen, hyaluronic acid and panthenol: the moisture-holding part of the formula.

How to use

• Cleanse and apply toner.
• Spread a generous layer over the face.
• Pat lightly until absorbed.
• Follow with moisturiser, and with sunscreen in the morning.

Good to know

• Size: 30g dropper bottle.
• This serum replaces Medicube’s AGE-R Glutathione Glow Serum, and some retailers still use that name. Medicube changed the ingredients and swapped the 50ml black bottle for the 30g amber one.
• Contains added fragrance.
• Patch-test before first use and stop if irritation develops.
