The best facial cleansers contain glycerin, which is often linked to acne.
And, according to a new study, the ingredients in some of the most popular cleansers may be a factor in acne.
According to the Journal of the American Academy of Dermatology, which published the study, one of the ingredients of Mederma Facial Cleanser (known as the Mederma Skin Care Line) was linked to an increased risk of acne.
This ingredient, which has a long history of acne, was linked with an increase in breakouts, a new analysis by researchers at the University of North Carolina found.
“We found a statistically significant association between acne severity and the glycerine content of the product,” Dr. Mark Bresch, the lead author of the study and a professor of dermatology at the university, told the Journal.
The researchers looked at Medermas own ingredients and the ingredients found in other cleansers to find out what was driving acne in the first place.
One ingredient in the Mederama line, glyceric acid, is found in a variety of products, from face and body scrubs to toothpaste and body wash.
Glyceric acids are widely used in cosmetic products and can be found in many skin care products, including face scrubs, body scrays, and facial cleanses.
Glycolic acid is found mainly in salves, facial creams, and toners.
Glycosaminoglycans, which are a group of amino acids, are also found in cosmetics, such as lotions, lotion emulsifiers, and soaps.
In this study, researchers compared the glycolic acids in Mederamas scented and non-scentated cleansers.
They also analyzed the glycosaminoglycerides in the products to find which ones were most common in the cleansers’ ingredients.
While the study found that glyceridic acid was the most common glycosamine, it wasn’t the only ingredient that was linked.
Glyceryl isomer, a glycosylated derivative of glycerol, was found in about half of the cleanser’s ingredients.
Glycyrrhizin, a derivative of lactic acid, was also found more often than glycerocaprylyls or glyceroxides.
Another ingredient that appeared to be linked to higher acne severity was the glyceryl triacylglycerol and triacylandroacylglucoside.
Glycation-related free radicals, or radicals that can cause damage to DNA, proteins, and DNA-repairing enzymes, are a common culprit behind acne.
They are also linked to skin problems including rosacea, psoriasis, eczema, and psorophilia.
Bresch said this is the first study that has found a link between glyceraldehyde and acne.
“We’ve never seen a case of a glyceral product with an increased incidence of acne,” he said.
“We also found that the glycation-associated free radicals are also related to skin aging.”
Brosch said that, as with most cosmetic products, it’s important to remember that acne is a disease that can be managed with regular care and a healthy skin.
He added that the results from the study do not mean that glycolaldehyde should be avoided.
“As we continue to investigate the role of glycolate on acne and to look at its role in skin aging, we need to be mindful of its role as a skin moisturizer, as well as its potential for increased acne risk,” he wrote.
