I have received countless inquiries from people with celiac disease or gluten intolerance who suffer from sensitive skin and are no strangers to allergic reactions. For years I myself wondered why some of even the most reputable natural cosmetic brands would bring my eyes to tears. It turns out that gluten was a contributor, but so were a few other sneaky ingredients.

While a few doctors argue that the gluten molecule is too large to be absorbed into the skin and is little risk, expert gluten-doctors Dr. Vikki Petersen and Dr. Ken Fine will warn you to stay away from gluten even in its topical form. This is for two reasons:

1. Products may inadvertently come into contact with mucus membranes (eyes, nose, mouth)
2. Many people experience skin irritation from gluten applied to the skin

But what if you are avoiding topical gluten and still suffering from allergic reactions?

Being gluten sensitive predisposes you to other allergies or sensitivities. So even if a product does not contain some of the most unnatural and common offenders like parabens, petro chemicals, phthalates, mercury, lead, hydroquinone, formaldehyde, coal tar or lauryl sulfates, you may be reacting to one of the ingredients.

Here are some of the more common natural ingredients that can irritate sensitive skin:

• lavender: Even though it is typically thought of of soothing or calming, many people do experience allergic reactions.

• bismuth oxychloride: This mineral makeup additive creates a healthy-looking shimmer effect, but may contain irritating heavy metals.

• chamomile: Though less common, this calming flower can also product topical allergies.

• carmine: Sometimes thought of as “the only true red found in nature,” this bright red pigment is made by grinding up beetle parts and causes skin irritation to many.

• tea tree oil: Especially if undiluted, this acne-fighting oil can cause skin irritation.

If you are using natural, gluten-free personal care products, but still having allergic reactions, try comparing ingredients in products that irritate to find the culprit.
