How it works

The Nosca9 Trouble Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Allantoin, named fourteenth on its own ingredient list. The same list carries Succinic Acid, Tocopherol and Ceramide NP, so the active is not the only thing on it worth naming. How much of the Allantoin 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 Fation sells in Korea, Allantoin and all.

Key benefits

  • Allantoin, the active this serum is built around
  • Succinic Acid on the same list, an active
  • Tocopherol on the same list, an antioxidant
  • Ceramide NP on the same list, a barrier lipid
  • Artemisia Princeps Leaf Extract and Centella Asiatica Extract further down the same list
  • Pyrus Malus (Apple) Fruit Extract and Panthenol further down the same list

Key actives

Allantoinactive

Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. On this serum's own ingredient list it is named fourteenth.

Succinic Acidactive

Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here. It is named eighteenth on this serum's list, alongside Allantoin.

Tocopherolantioxidant

Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer. It is named twenty-fourth on this serum's list, alongside Allantoin.

Ceramide NPbarrier lipid

Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. It is named twenty-seventh on this serum's list, alongside Allantoin.

Sodium Heparinpolysaccharide

Sodium Heparin is a sulfated sugar chain, structurally close to the heparan sulfate skin makes itself. In a formula it is a strong humectant. It is named twentieth on this serum's list, alongside Allantoin.

Payment and security

How to use

  1. Use it after cleansing and toning, while the surface is still slightly damp.
  2. Press three or four drops over the face and neck rather than rubbing them in.
  3. Wait until it feels dry to the touch, then apply your moisturiser over the top.
  4. Do not apply it over a cream or an oil, since a light serum cannot get through a finished occlusive layer.

Worth knowing

  • Patch test this serum on a small area and wait a day before using it more widely, especially with Allantoin on the list.
  • Introduce this serum on its own for the first week, so anything your skin does is traceable to the Allantoin rather than to three changes at once.

What professionals say

  • Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

  • People with dry, flaky skin are more likely to see a benefit from using vitamin E because it enhances moisturization.
