Who doesn’t find it annoying when the skin care products that are supposed to moisturize, rejuvenate, and exfoliate the skin instead causes some part of your skin to break out into a rash? Contact dermatitis is one of the most common skin conditions. As an irritant dermatitis, these reactions are usually pretty mild and will sometimes go away completely once your skin has time to acclimate. Allergic dermatitis may cause a stronger rash but still typically subsides after a few days. (Eczema, or atopic dermatitis, is another kind of skin rash that isn’t connected to coming into contact with foreign substances, but can nevertheless complicate and provide further irritation to the skin.)
Currently, the best plan of action for severe contact dermatitis is to conduct skin allergy tests to determine what is causing the dermatitis and then avoiding those products and substances that are causing the skin rash.
New Research Offers Potential to Treat Contact Dermatitis
One of the central mysteries about why contact dermatitis has to do with the size and structure of the molecules that get absorbed into the skin. Contact dermatitis is the immune system reacting to a foreign substance, and T-Cells are the immune system’s primary detection cells. But how is this possible when T-Cells can’t detect molecules as small as those that cause dermatitis? Dermatology researchers now think they have an answer. The CD1A molecule binds to several different types of chemicals, including some that are found in skincare products, like benzyl benzoate and benzyl cinnamate. Once these molecules are bound together the T-Cells can detect and there is the possibility for dermatitis to occur. What’s more, another chemical, farnesol, goes even further by creating a deeper bond that changes the shape of the CD1A molecule itself.
What does this Research Mean?
At the very least, it means dermatologists will be able to provide a fuller explanation of Why Skin Creams Give You Rashes. Ideally, new molecules will be discovered that can bind with CD1A molecules with leading to contact dermatitis. These molecules would then block benzyl benzoate and benzyl cinnamate from binding with CD1A and minimize if not eliminate dermatitis as a result.
In some cases, it may still be easier to simply avoid the substance that causes the contact dermatitis, but there are promising implications for future research and product development. In the future, medical professionals with a latex allergy can apply a topical skin treatment neutralizes allergic contact dermatitis more effectively than ever before. It’s also possible that new CD1A-binding molecules can used to create entirely new lines of more powerful, but still hypoallergenic, skin care products. If you read skin care blogs, like this one, you’ll invariably come across the advice to experiment with different products. This advice is a lot easier to follow when there’s negligible risk of a skin rash as a side effect. Thus, it’s also likely that more people would start and stick to a daily skin care routine.
