Mask Acne (Maskne): Causes and Treatments.

Research suggests that “maskne" probably arises from 3 factors - follicular occlusion in combination with mechanical stress (like friction, pressure, occlusion) & changes in the skin microbiome (from heat, changes in pH and moisture).

Strategies to prevent and treat maskne involve targeting all three of these factors. The frustrating thing about treating maskne is everyone has their favourite tips - dermatologists and public alike. This leads to confusion about what really to do. There are countless products that have been discussed so far. Regardless of which products one feels are a must buy - the basic principles are the same- wear a clean good fitting dry mask, keep the skin clean is as gentle of a manner as the person’s skin allows and gently moisturize it afterwards. Some people need to focus on all three to prevent and limit maskne, some need to focus on only one or two.

Wearing a good fitting, clean, dry mask can limit friction - so can avoiding touching and adjusting it while it’s on the face. If a mask becomes wet from sweating or breathing it needs to be replaced with a dry one.

Cleansing and moisturizing the face daily to twice daily is important. Overdoing the cleaning is to be avoided as it overdries the skin. Commercially available mild cleansers with salicylic acid can be a good choice. Moisturizers with hyuronic acid are often recommended and so are those with ceramides, niacinamide and glycerin. Limiting the use of heavy occlusive makeup and skin care products is important in preventing maskne.

Maskne refers to the development of acne from mask wear. It is increasingly common during the COVID 19 pandemic.

In some cases, use of antifungal agents like clotrimazole or can be considered in treatment. Ivermectin has also been used. Spot treatments with traditional acne treatments like benzoyl peroxide and retinoids can be considered but one must be cautious about excessive irritants on the face if a mask will be reused any time soon. Spot treatment with over the counter mild hydrocortisone can also be used. Stronger steroids are to be avoided.

Reusable masks should be washed in mild detergents preferably those that low in irritants & fragrance that remain in the mask after washing.
