There are 2 main moisturizers: moisturizer and desiccant.
An occlusives, or coating, will coat the skin with a thin film to prevent water from evaporating. Common coatings include: petrolatum (petroleum jelly), oils (base oils), propylene glycol and dimethicone (derivatives of silicone). However, these substances have a disadvantage is that using more will cause the skin to become clogged.
Desiccants (Humectants) such as Glycerin and Hyaluronic Acid have a different mechanism of action for blocking substances. Humectants have very good water-absorbing capacity (hydrated) so it can draw water into the skin. However, desiccant can also be a traitor if used improperly. Their activity is not one-dimensional: although they pull water from the environment into the skin to help retain water, but in dry air they draw water from inside the skin (in the deep and mesodermal cuticles. ) out, increasing dry skin. Therefore, the desiccant will work better if combined with the coating, the water will never be pulled out because the coating has already stopped.
Therefore, the best moisturizer for dehydrated skin is one that contains both a desiccant and a moisturizer. Because of the lack of water, you need to use moisturizers in the form of gel or gel cream (containing many desiccants) to increase the absorption of water to the skin, helping the skin to stay hydrated, thereby reducing peeling and reducing lubricant.
In a nutshell, for dry and oily skin due to dehydration, you should do the following:
Avoid long baths
Use a non-foaming cleanser or a little foam, with a pH below 7 (pH5.5 is the best)
Use a mineral spray containing desiccant after skincare.
Regularly use a water mask or lotion mask (every day or at least 2 times / week)
Apply lotion to the skin as soon as the skin is still slightly damp, so that skin is not too dry before applying it.
Add a gel or gel cream moisturizer, which contains both a desiccant and a moisturizer.
One more problem, I said that drinking lots of water doesn’t help relieve dry skin, but that doesn’t mean I advocate being lazy about drinking water. You still have to drink enough 2 liters of water a day to work properly in the body, eliminate toxins, so that the skin is beautiful.
If you apply the rules well, your skin barrier will gradually improve, so that your skin will shift from dry, flaky skin to hydrated, hydrated skin. Try to be persistent to have a healthy skin.
