Does COSRX Hydrium Centella Aqua Soothing Ampoule work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using COSRX Hydrium Centella Aqua Soothing Ampoule:

  • Moderate moisturizing. It has a moisturizing rating of 4.0 out of 10.
  • Soothing: COSRX Hydrium Centella Aqua Soothing Ampoule contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, COSRX Hydrium Centella Aqua Soothing Ampoule is quite moisturizing, with a moisturizing rating of 4.0 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.0 out of 10, primarily due to the high content of Glycerin (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, COSRX Hydrium Centella Aqua Soothing Ampoule has a zero anti-wrinkle rating.

It contains Centella Asiatica Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Centella Asiatica Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in skin-protecting antioxidants

We estimate that COSRX Hydrium Centella Aqua Soothing Ampoule is rich (> 3%) in antioxidants, specifically Centella Asiatica Extract (est. ≈6.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Skin soothing and calming potential

Based on the ingredient list analysis, COSRX Hydrium Centella Aqua Soothing Ampoule is rich (> 5%) in soothing ingredients, particularly Centella Asiatica Extract (est. ≈6.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
