Gluten-free diets are increasing in popularity. In the US, 1 in 133 people are intolerant to gluten, which is also know as celiac disease.

What is gluten? Gluten is a protein found in wheat, barley, rye and millet.

There is controversy about whether individuals with celiac disease need to avoid topical skin care products containing these wheat proteins. Oral consumption of gluten can cause eczema, psoriasis, and dermatitis which is sometimes called “gluten rash”. Some people worry about cross contamination i.e. using a hand lotion with wheat proteins then preparing food.

If gluten in your skin care is a concern, avoid ingredients like barley, wheat, and triticum. Oats and oatmeal do not contain wheat protein but are usually processed in a facility where cross contamination is possible.

Wheat germ oil is commonly used in skin care products but the wheat protein has been removed so it shouldn’t cause a reaction.

It is best to avoid lip balms(and any products that may be ingested) that contain wheat proteins.

All of my products are gluten free and I recommend Intense Moisture Therapy to sooth eczema rashes.

Q: I hear a lot about Retin A and skin creams with retinol…should I be using one? And what’s the difference?

A: There are a variety of skin care products on the market that incorporate Vitamin A derivatives, commonly called retinols or retinoids. These products benefit the skin in multiple ways but most importantly they increase skin cell turnover. This increased cell activity helps prevent blackheads, smooths fine lines, lessens the appearance of wrinkles, and lightens pigment spot from age or acne.

Tretinoin (the generic name for Retin A) is a prescription retinoid. Tretinoin is sold under several brand names: Retin A, Retin A Micro, Renova, Atralin to name a few. These products require a prescription so your dermatologist will determine which one is best for you based on your skin type.

Many over the counter products contain retinol. Nightly Therapy is one of my best selling products, it contains time released retinol and is safe to use around the eyes.

Most people can benefit from incorporating a retinol into their skin care routine. Retinols should always be used at night since sunlight breaks down the active ingredients. SPF must be worn during the day because the increased skin cell turnover will leave your skin less protected.

If your have no breakouts and very few fine lines, use a light retinol once or twice a week at night to exfoliate and help prevent the signs of aging.

If you have acne, visit a dermatologist and get a prescription for tretinion.

If you are fighting more pronounced signs of aging, use a retinol every night. Layer it under your moisturizer if your skin is dry.

Retinols are a great tool for increased skin health!

Q: I have red bumps on my upper arms. They get worse during the winter and got really bad when I was pregnant. It’s embarrassing to wear sleeveless tops! What can I do to treat them? Help!

A: Red bumps that appear on the upper arms are known in the medical community as keratosis pilaris. It is a very common problem, often due to genetic factors and can be easily kept under control. The bumps arise from excess keratin production which can clog the hair follicle. Use a gentle cleanser and a glycolic body lotion on the affected area to keep the skin smooth and clear.

If the problem persists or worsens, make an appointment to see your dermatologist.

The simple answer is yes.

However, there are many factors that can extend the shelf life of the fabulous products you work hard to be able to purchase!

Most skin care products have a symbol on the label that lets you know how long the product is good once it’s been opened: the most widely used icon is a jar with and open cap and a number on it. The number denotes how many months the product is guaranteed from the day you open it.

Most products are good for 6-24 months once they have been opened. Packaging plays a large roll in how this number is determined. An airless pump keeps a product fresh for much longer than a wide mouth jar. The less contamination (for the air or your fingers), the longer your product with stay fresh and stable.

If a product changes color or separates, chances are good that is has expired.

Vitamin C is difficult to keep stable and has a short shelf life. It oxidizes (turns brown) when it is no longer effective.

Most skin care products are sold in containers determined to be the amount an average person would consume, with regular use, in a 3-4 month period.

If you are worried about your products expiring before you use them up, stick with items sold in pumps and tubes instead of jars and store them in a dark, cool environment.

Is there a downside to using expired products?

Again, the simple answer is yes.

When a product is past the expiration date it is no longer effective. For something like a basic moisturizer, this isn’t a concern but for a product containing sunscreen or retinol it’s important to make sure the active ingredients aren’t past their prime.
