Does Infrequent Bathing Contribute to Eczema Flare-Ups? - Dermatology

Is atopic dermatitis related to not washing properly during bathing?


I have had atopic dermatitis on my forehead, the inner elbows, and the backs of my knees for a long time, with flare-ups and periods of relief.
I do not shower every day; instead, I wash every 2 to 4 days using just water and a towel.
Each time, I feel that these areas are particularly oily, and I scrub off a lot of dirt.
Could the accumulation of dirt be causing my dermatitis? Should I increase the frequency of my showers or maintain my current routine? When showering, should I scrub off the flaky skin? My skin feels really uncomfortable due to its roughness and oiliness.
A doctor previously advised me to apply lotion after showering, but it feels like I just worked hard to wash off the oil and dirt, and then applying lotion makes my skin oily again.
Could this actually make things worse?

More Info


Eczema, or atopic dermatitis, is a chronic inflammatory skin condition that can be influenced by various factors, including bathing habits. Your question about infrequent bathing and its potential contribution to eczema flare-ups is quite relevant, especially considering your experience with the condition on specific areas of your body such as the forehead, inner elbows, and behind the knees.

Firstly, infrequent bathing can indeed contribute to the exacerbation of eczema symptoms. When you do not wash your skin regularly, oils, sweat, and environmental pollutants can accumulate on the skin's surface. This buildup can lead to irritation and inflammation, which may trigger or worsen eczema flare-ups. The skin's natural barrier function is compromised in individuals with eczema, making it more susceptible to irritants and allergens. Therefore, maintaining a regular bathing routine can help remove excess oils and debris, potentially reducing the frequency and severity of flare-ups.

However, it is essential to strike a balance in your bathing routine. While increasing the frequency of your baths or showers may be beneficial, it is crucial to consider the method and products used. Using harsh soaps or hot water can strip the skin of its natural oils, leading to further dryness and irritation. Instead, opt for lukewarm water and gentle, fragrance-free cleansers specifically formulated for sensitive skin. Limiting bath time to about 10-15 minutes can also help prevent excessive drying.

Regarding your concern about the accumulation of skin flakes and oiliness, it is advisable to gently exfoliate the affected areas during bathing. However, be cautious not to over-exfoliate or use abrasive materials, as this can further irritate the skin. A soft washcloth or a gentle exfoliating glove can be effective in removing dead skin cells without causing damage.

After bathing, the application of moisturizer is crucial for individuals with eczema. While it may feel counterintuitive to apply lotion after washing off oils and dirt, moisturizing helps to restore the skin's barrier and lock in hydration. Look for thick, emollient creams or ointments that are free from fragrances and irritants. Applying moisturizer while the skin is still damp can enhance absorption and effectiveness.

If you find that your skin feels excessively oily after applying moisturizer, consider using a lighter formulation or adjusting the amount you apply. It may take some experimentation to find the right balance that keeps your skin hydrated without feeling greasy.

In summary, increasing your bathing frequency to every day or every other day, using gentle cleansing methods, and consistently applying a suitable moisturizer can help manage your eczema more effectively. If you continue to experience discomfort or flare-ups despite these changes, it may be beneficial to consult a dermatologist. They can provide personalized recommendations and may suggest additional treatments, such as topical corticosteroids or other medications, to help control your eczema symptoms.
