Uses of Dimethicone

This medication is used as a moisturizer to treat or protect against dry, rough, scaly, itchy skin and mild skin irritations (e.g., diaper rash, skin burns from radiation therapy). Emollients are materials that make softer and hydrate the skin and decrease itching and flaking. A few products (e.g., zinc oxide, white petrolatum) are used mainly to protect the skin against irritation (e.g., from wetness).

Dry skin is caused by a loss of water in the upper layer of the skin. Emollients/moisturizers work by creating an oily coating on the top of the skin which contains water in the skin. Petrolatum, lanolin, mineral oil and dimethicone are common emollients. Humectants, such as glycerin, lecithin, as well as propylene glycol, draw water into the outer layer of skin. Numerous products also have ingredients that make softer the horny chemical (keratin) that holds the top layer of skin cells together (e.g., urea, alpha hydroxy acids such as lactic/citric/glycolic acid, and allantoin). This helps the dead skin cells fall off,  the skin keep in more water, and leaves the skin feeling smoother and much softer.

How to use dimethicone

Use this product as guided. Many products require priming prior to use. Follow all instructions on the product package. If you are unsure about any of the information, consult your doctor or pharmacist. Several products need to be shaken prior to use. Check the label to see if you should shake the bottle well before using. Apply to the affected areas of the skin as needed or as directed on the label or by your doctor. How often you apply the medicine will depend on the product and your skin condition. To treat dry hands, you may need to use the product every time you wash your hands, applying it throughout the day.

If you are using this product to help treat diaper rash, thoroughly clean the diaper area well before use and allow the area (blank) dry before applying the product.

If you are using this product to help treat radiation skin burns, check with radiation personnel to see if your product can be applied before radiation therapy.

Follow all the instructions on the label for proper use. Apply to the skin only. Stay away from sensitive places such as your eyes, inside your mouth/nose, and the vaginal/groin area, except if the label or your doctor directs you otherwise. Check the label for instructions about any areas or types of skin where you should not apply the product (e.g., on the face, any areas of broken/chapped/cut/irritated/scraped skin, or on a recently shaved area of the skin). Consult your doctor or pharmacist for more details.

Use this medication on a regular basis to get the most benefit from it. The majority of moisturizers require water to work well. Apply the product after bathing/showering while the skin is still damp. For very dry skin, your doctor may advise you to soak the area before using the product. Long, hot, or frequent bathing/washing can aggravate dry skin.

If your problem continues or gets worse, or if you consider you may have a serious medical problem, seek immediate medical attention.
