Orthotamin Vitamin C Eye Cream | Orthotamin · Retinol | 0.5 fl oz

Korean vitamin C eye cream from Mommy Care is a 15 ml eye cream made in Korea, built on pure ascorbic acid rather than a derivative, with retinol, HPR, and niacinamide.

What Orthotamin Vitamin C Eye Cream is

Orthotamin Vitamin C Eye Cream (오쏘타민 비타민C 아이크림) is the eye-area tube in Mommy Care's Orthotamin line, in a 0.5 fl oz (15 ml) tube with a metal applicator tip. It lists pure ascorbic acid at 10,000 ppm — 1% of the formula — alongside retinol paired with HPR, plus niacinamide and glutathione.

Orthotamin is the vitamin line Mommy Care built around ascorbic acid, known first for its ampoule. This tube carries the same vitamin blend into a format made for the thinner skin around the eyes, at a formula pH of 4.6.

How to use it

How do you apply a vitamin C eye cream?

Use it after cleansing and toner. Squeeze a rice-grain amount onto the metal tip and dot it under each eye along the orbital bone — the ridge you can feel about a finger-width below the lash line.

Pat it in with your ring finger rather than dragging. The skin there is thin, and patting moves less of it. Keep the cream off the lash line and out of the eye itself.

Should a retinol and vitamin C eye cream go on morning or night?

Night is the simpler slot, because retinol and ascorbic acid both prefer to sit undisturbed and neither needs daylight. If you use it in the morning instead, follow with sunscreen.

If retinol is new to you, start at two or three nights a week for the first two weeks, then move to nightly once the skin has settled. The 15 ml tube lasts roughly two to three months at a rice-grain dose per eye.

Before you use it

For external use only. Keep it out of the eyes; if it gets in, rinse with plenty of water. Avoid broken or irritated skin, and stop using it if redness, swelling, or itching develops — the Korean label also notes to consult a specialist if that happens after sun exposure.

If your skin is reactive, patch test on the inner forearm for a day or two before the first full application. If you are pregnant or nursing, check with your doctor before using any retinol product. Read the full ingredient list on the box if you have known sensitivities.

Reading the label

Pure ascorbic acid vs vitamin C derivatives — what is the difference?

Pure ascorbic acid differs from derivatives such as 3-O-ethyl ascorbic acid, sodium ascorbyl phosphate, and magnesium ascorbyl phosphate in that it is vitamin C in its unconverted form. Derivatives are more stable in a jar but have to convert on the skin first.

Unconverted ascorbic acid needs an acidic base to stay stable, which is why this formula is built at pH 4.6. The ingredient list carries both approaches: ascorbic acid second from the top, and three derivatives further down.

Retinol vs HPR (hydroxypinacolone retinoate) — how do they differ?

Retinol differs from HPR in that retinol converts inside the skin in two steps before it reaches its active form, while HPR is an ester of retinoic acid that binds retinoid receptors directly, without that conversion.

Korean formulas often list the two together — the marketing shorthand is "double retinol" — and Orthotamin lists them at 1,000 ppm combined. The tube also lists retinyl palmitate, the gentlest retinoid of the three.
