How it works

Retinol leads the ingredient panel on this serum. Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises. On this panel it sits alongside Niacinamide, Cholesterol and Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Key benefits

  • Retinol named on this product's own ingredient panel, near the top of it
  • Niacinamide on the same panel, the formula's active
  • Cholesterol on the same panel, the formula's barrier lipid
  • 30 ml to a unit
  • Korean GS1 barcode matched against a Korea sourcing supplier's record for this item

How to use

  1. Cleanse and tone, then make sure skin is fully dry.
  2. Dispense a small amount and press evenly over the face at night, avoiding the eye area.
  3. Follow with a moisturizer rather than skipping that final step.
  4. Use sunscreen the next morning without exception, not only when skin looks irritated.

Worth knowing

  • Introduce it two to three nights a week at first and watch how the skin responds before moving to nightly use.
  • Pair it with a daily sunscreen step, since brightening and exfoliating actives can make skin more reactive to sun exposure.
