If this is the only moisturizer that you apply at a time, check out our suggestions for different skin types:
Oily and combination skin: Moisturizing rating of 2 - 6 with high Humectancy and low Occlusivity
Normal skin: Moisturizing rating of 4 - 7 with high Humectancy and moderate Occlusivity
Dry skin: Moisturizing rating of 7 - 10 with high Humectancy and high Occlusivity

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using The Ordinary EUK 134 0.1%:
Quite moisturizing: The Ordinary EUK 134 0.1% has a moisturizing rating of 5.0 out of 10.
Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, entirely due to the high content of Propanediol (est. ≈99.9%).
Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.
Please refer to the Ratings section below for details of the moisturizing rating calculation.

According to various studies, a formula made up of 10% humectants will significantly increase skin hydration. Some studies also suggest that any further icrease in the consentration of humectants does not translate inty any more hydration and may even be dehydrating.
To achieve maximum Humectancy, the product should have humectants with a total score of 10 and more.

The most occlusive product possible is 100% petrolatum (hello Vaseline Jelly). According to studies, however, even 10% petrolatum can achieve almost the same mosturizing effect.
The occlusive properties of petrolatum are at least twice as superior as other occlusive ingredients. This is why, in order to match the moisturizing efficacy of 10% petrolatum, a product needs to contain at least 20% of other occlusives.
Our benchmark for maximum Occlusivity is 20 (and the petrolatum score is always doubled).
