How it works

The Green Tangerine Vitamin C Dark Spot Serum Alpha is a serum, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Ascorbic Acid, named thirty-sixth on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid stays on the skin, and for how long, is decided by the serum format rather than by the list alone. goodal sells this Ascorbic Acid serum in Korea, and this is that version.

Key benefits

  • Ascorbic Acid, the antioxidant this serum is built around
  • Niacinamide, Allantoin, Adenosine and Dipotassium Glycyrrhizate on the same list, actives
  • Madecassoside and Asiaticoside further down the same list
  • Tocopheryl Acetate and 3-O-Ethyl Ascorbic Acid further down the same list
  • Ascorbic Acid named thirty-sixth on the manufacturer list printed on this page

Key actives

Ascorbic Acidantioxidant

Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. It is the entry this serum is named after, and the list carries it.

Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fourth on this serum's list, alongside Ascorbic Acid.

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. The panel names it twentieth on this serum's list, beside Ascorbic Acid.

Adenosineactive

Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it twenty-first on this serum's list, beside Ascorbic Acid.

Dipotassium Glycyrrhizateactive

Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named thirty-second on this serum's list, alongside Ascorbic Acid.

Payment and security

We accept

How to use

  1. After toner, while skin is still slightly damp, apply Green Tangerine Vitamin C Dark Spot Serum Alpha 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.

Worth knowing

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

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

  • Using topical vitamin C can result in less cell damage and better-looking skin.

    Melissa Piliang, MDDermatologist, Cleveland Clinic
  • 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.

  • 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.
