Key actives

Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named fifth.

Folic Acidvitamin

Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend. It is named seventeenth on this serum's list, alongside Niacinamide.

3-O-Ethyl Ascorbic Acidantioxidant

3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable. The panel names it third on this serum's list, beside Niacinamide.

Ferulic Acidantioxidant

Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often. The panel names it nineteenth on this serum's list, beside Niacinamide.

Hippophae Rhamnoides Fruit Extractplant extract

Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract. It is named eleventh on this serum's list, alongside Niacinamide.

How to use

  1. After toner, while skin is still slightly damp, apply RX Multi Vitamin Glow Serum 35ml to the face and neck.
  2. Press gently with your palms rather than rubbing, so it has a moment to absorb.
  3. Follow with moisturiser once it has sunk in.

How it works

The RX Multi Vitamin Glow Serum is a 35ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named fifth on its own ingredient list. The same list carries Folic Acid, 3-O-Ethyl Ascorbic Acid and Ferulic Acid, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum Heimish sells in Korea, Niacinamide and all.

Worth knowing

  • Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
  • This list names Fragrance, so skip it if fragrance components are something you avoid.
