Many people experience dry, itchy skin even after applying moisturizer, leading to questions about why dryness persists. As we age, our skin naturally produces less oil, which makes it more susceptible to dryness. Dr. Marisa Garshick, a board-certified dermatologist at MDCS: Medical Dermatology and Cosmetic Surgery, notes that this can manifest as roughness, dullness, and increased irritation.

Certain medical conditions may also contribute to persistent dryness. Dr. Michael Tassavor emphasizes that eczema, psoriasis, and issues like hypothyroidism can result in flaky skin. Additionally, contact dermatitis from skincare products or other substances can worsen dryness.
Harsh cleansers are a common factor in ongoing skin dryness. Dr. Tassavor warns that cleansers with strong surfactants can strip the skin of essential oils, leading to vulnerability to irritation. It is advisable to avoid harsh soaps and heavily fragranced products, as they may compromise the skin barrier. Instead, Dr. Garshick suggests using gentle, hydrating cleansers containing ingredients like ceramides or glycerin.
Over-exfoliating or not exfoliating enough can also lead to dry skin. Dr. Brendan Camp explains that inadequate exfoliation can result in a buildup of dead skin that feels coarse, while excessive exfoliation can strip sebum from the skin, impairing its moisture retention. To correct this, Dr. Garshick recommends finding a balance with gentle exfoliators and possibly eliminating exfoliating products if the skin is irritated.
Cold weather and dry indoor air can exacerbate skin dryness. Dr. Garshick points out that heating systems reduce humidity, worsening hydration levels in the skin. A humidifier can be beneficial in combating this dryness by adding moisture back into the air.
Hard water may also contribute to skin issues by leaving mineral residues that irritate sensitive skin. Dr. Garshick suggests using a shower filter or water softener to mitigate these effects, although evidence on long-term benefits is limited.
Additionally, the type of moisturizer and how it's applied matter. Lightweight lotions may not provide enough hydration. Dr. Garshick recommends richer creams, especially those with humectants, emollients, and occlusives. Applying moisturizer on damp skin helps in locking in moisture.
If dryness persists despite following these guidelines or is accompanied by severe symptoms like itching or scaling, consulting a dermatologist is advisable to rule out underlying conditions.
