Acne is a skin condition that develops when pores become blocked with oil, dead skin cells and bacteria. Black heads, white heads, pustules, cysts and papules can all develop as a result of this blockage. They can appear anywhere on the body, including the forehead. Acne and many conditions---such as over washing or using harsh cleansers---can aggravate acne prone skin and make it dry and patchy. Fortunately, there are many ways to treat dry patches of skin on the forehead.
MayoClinic.com recommends applying a moisturizer to your forehead to help smooth out dry skin and seal in water. Not only can this eliminate dry skin patches, it can help makeup go on smoother while attempting to conceal acne. Moisturize soon after washing your face or right after bathing to trap water in the surface skin cells.
Choose a moisturizer that is labeled "noncomedogenic" and "oil-free," meaning it will not clog pores and create additional acne. Unfortunately, this is not a guarantee that it won't cause breakouts. Experiment with different moisturizers until you find one that works for your skin type.
According to Acne.org, jojoba oil can help remedy dryness, even on acne prone skin. Jojoba is an extract of the jojoba tree seed. It is not actually an oil, but a wax ester that is similar to the oil produced on the human skin. Unlike water based moisturizers, jojoba oil does not evaporate, thereby allowing it to provide long lasting moisturization. Add a couple of drops to your regular facial moisturizer and mix in the palm of your hand before liberally smoothing over your forehead and face.
Reconsider Acne Regimen
Some over-the-counter and prescription acne products like benzoyl peroxide or tretinoin can cause irritating side effects like dryness and peeling. Consider switching to a different medication or gradually increasing your dosage so that your skin has time to get used to the acne product.
