It happens when the outer layer of the skin peels off in large pieces, leaving a wound-like appearance and, sometimes, may even bleed. But again, what causes scaly skin and how can it be treated or managed? Let's find out what a dermatologist has to say about it. Possible Causes Of Scaly Skin In an interaction with the OnlyMyHealth team, Dr Shireen Furtado, Senior Consultant - Medical and Cosmetic Dermatology, Aster CMI Hospital, Bengaluru, refers to scaly skin as a symptom of various prevalent dermatological conditions. Among these, psoriasis is a chronic autoimmune disorder characterised by the rapid proliferation of skin cells, leading to thick, silvery scales, she says.   She further adds that conditions like eczema or atopic dermatitis can also result in dry, itchy patches that can become scaly when scratched. Additionally, seborrhoeic dermatitis, commonly known as dandruff when it affects the scalp, can also lead to flaky, scaly skin in other body areas. This type of skin problem affects 5% of the global population, according to StatPearls Publishing. Other potential causes include fungal infections like tinea, which can produce scaly lesions, and ichthyosis, a genetic disorder that results in dry, scaly skin due to a defect in the skin's ability to shed dead cells. Can The Weather Contribute To The Skin Condition? According to Dr Furtado, changes in temperature, humidity, and exposure to environmental elements can greatly affect skin health. Citing examples, she says, "Dry and cold climates can cause the skin to lose more moisture, leading to dryness and scaling. On the other hand, high humidity levels can present different challenges, potentially causing skin irritation or worsening scaling." Depending on these interactions, a person can develop effective skincare practices suited to specific environmental conditions, the doctor advises. When To Seek Medical Attention? While scaly skin is usually harmless, if it is due to an underlying medical condition, it is best to consult a medical professional or dermatologist. Keep a check on the duration of the skin problem and watch out for any accompanying symptoms, such as severe itching, redness, or inflammation. If , such as oozing or increased warmth in the affected area, are present, it is advisable to seek professional medical advice. Additionally, if the scaly skin appears suddenly, spreads rapidly, or is associated with other systemic symptoms like fever or fatigue, these could be warning signs that require prompt attention from a healthcare provider.   Treatment Options And Management Tips Dr Furtado recommends products containing ingredients like salicylic acid, urea, or alpha-hydroxy acids, which help exfoliate and hydrate the skin, promoting a smoother texture. Additionally, moisturisers enriched with ceramides or glycerin can provide significant relief by restoring the skin's natural barrier and preventing moisture loss, the doctor shares, adding that it is also beneficial to look for creams or lotions that contain natural oils, such as coconut oil, which can further enhance hydration and soothe irritation. At the end of the day, if you have any skin troubles, consulting with a healthcare professional can provide personalised recommendations based on individual skin types and conditions.
