In a previous article, we covered how to select the best moisturizer for dry skin. We suggest your read the article so that the description of humectants make sense to you.
What is a Humectant?
Humectants help in improving the dryness of the skin by pulling the water from the air as well as in the skin layers to hydrate the Stratum Corneum. 
Any moisturizer you are using should contain at least one humectant. Particularly if you are suffering from dry skin, or worse cracked skin, a good humectant, or combination of humectants, will help your moisturizer hydrate your skin.
Which Humectant moisturizer should I look for in my moisturizer?
There are many types of humectants available in moisturizers. they can be categorized as natural or synthetic.
- Alpha hydroxy acid
- Butylene glycol
- Hyaluronic acid
- Lactic acid
- Sodium PCA
- many more..
As with everything, it is hard to say one is better than another in a given moisturizer. It depends on the concentration of each humectant in the formulation, as well as the interaction with the other ingredients.
What really matters is that you look for at least one of the humectants listed above in your moisturizer in the ingredient list. The image below shows you the ingredients with humectants highlighted in purple.
It is also important to see where the humectants are listed in the ingredients. Most ingredients labels are required to list from highest concentration to lowest concentration in the actual formula. So if you see the humectants towards the end of the ingredient list, you most likely won't have much in your moisturizer.
As with anything, finding the right moisturizer, oil, or product for your dry skin takes research. If your dry skin issues are chronic in nature, rather than seasonal, you should take extra care to look for the right ingredients for you.
Humectants are a key ingredient for any moisturizer for dry skin. Look for the ones listed above, and make sure you check where the humectants are in the list of ingredients.
Dry skin needs extra help, and the right humectant can make a world of difference.
