How it works

The C-Niacin Toning Cream is a 50ml cream, used as the last skincare step, morning and evening, over serum. The active it is built around is Niacinamide, named seventh on its own ingredient list. The same list carries Retinyl Palmitate, Biotin and Thiamine HCl, 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 cream format rather than by the list alone. This is the Original Korean Formula, the cream Isntree sells in Korea, Niacinamide and all.

Key actives

Niacinamideactive

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

Retinyl Palmitateactive

Retinyl Palmitate is retinol bound to a fatty acid. It is the mildest common retinoid because skin has to make three conversions before it becomes active, which also makes it the least likely to cause flaking. The panel names it forty-first on this cream's list, beside Niacinamide.

Biotinvitamin

Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas. The panel names it forty-second on this cream's list, beside Niacinamide.

Thiamine HClvitamin

Thiamine is vitamin B1, supplied as its hydrochloride salt so it dissolves in water. It is a conditioning vitamin and usually appears as part of a B-complex. It is named forty-third on this cream's list, alongside Niacinamide.

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 forty-fourth on this cream's list, alongside Niacinamide.

How to use

  1. Use it as the final leave-on step so nothing thinner has to sit on top.
  2. Take a small amount, warm it briefly between your fingers, then press it over the face.
  3. Add a second thin layer only where the skin feels tight rather than everywhere.
  4. Do not introduce it in the same week as a new exfoliating acid, since you will not know which one caused a reaction.

Worth knowing

  • Patch test this cream on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
  • Retinyl is on this list, so keep this cream to the evening and build the nights up slowly rather than starting nightly.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

  • Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.

  • Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
