What are chapped skin and why do they occur?
Chapped skin consists of small, superficial cracks in the skin that mainly appear on the lips, hands, heels, and fingers. They result from a breakdown of the protective hydrolipidic film and excessive skin dehydration, making the skin too dry and too stiff to withstand normal mechanical stress. Targeted skincare products for dry skin are available in the store, as well as treatments for dry and chapped lips.
- Main causes: cold and wind (reduced peripheral blood circulation and drying of the skin’s surface) — heated and dry indoor air (ambient humidity < 40% weakens the hydrolipidic film) — excessive cleansing or harsh alkaline soaps (destruction of the hydrolipid film) — systemic dehydration (insufficient water intake) — repeated rubbing (hands, lips)
- Aggravating factors: constitutionally dry or atopic skin (skin barrier deficient in ceramides) — nutritional deficiencies (essential fatty acids, vitamins A and E) — drying medications (oral retinoids, diuretics) — systemic diseases (psoriasis, hypothyroidism, diabetes) — in children: thin skin, less diligent hydration, unprotected exposure to cold
- Location and severity: mild chapped skin (superficial, not bleeding) can be treated with topical care — deep cracks with bleeding, scabs, or secondary infection (redness, warmth, pus) require a doctor’s visit
What natural remedies can be used to treat and prevent chapped skin?
Treatment focuses on restoring the hydrolipid barrier and rehydrating the skin. Applying products to slightly damp skin (after a bath or shower) maximizes the absorption of emollient and occlusive active ingredients.
- Shea butter: a major nourishing agent—unsaponifiables (vitamins A, E, phytosterols) and unsaturated fatty acids—forms a protective occlusive layer over the cracks—apply as a balm to hands, lips, and heels before bedtime—safe for children ages 3 and up
- Glycerin: a key humectant — attracts and retains water in the skin’s outer layers — quickly relieves tightness — used undiluted, diluted to 30–50% in water, or incorporated into hand and foot creams
- Ceramides: structural lipids of the skin barrier—topical application restores damaged intercellular junctions—essential for atopic or constitutionally dry skin prone to recurrent chapping
- Aloe vera gel: soothes, moisturizes, and promotes healing of the mucous membranes and epidermis — apply to cracks several times a day — provides local anti-inflammatory action — perform a 48-hour patch test on reactive skin first
- Coconut oil: lauric acid (mildly antibacterial) + film-forming saturated fatty acids—nourishes and protects chapped lips and hands—apply a thin layer to affected areas
What specific treatments are available for chapped feet and lips?
- Cracked heels: Deep cracks in the heels (fissures) require keratolytic creams containingurea (20–40%) or salicylic acid to soften the hyperkeratotic layer—apply in the evening, cover with cotton socks to maximize absorption—follow with gentle exfoliation before application—very deep or bleeding fissures should be treated by a podiatrist
- Chapped lips: avoid licking them (saliva worsens dehydration)—do not pick at dead skin—use an occlusive lip balm containing shea butter, beeswax, or lanolin — reapply every 2 to 3 hours — use balms with SPF 15 to 30 during the day to protect against photoaging
- Chapped hands: Use a hand cream rich in ceramides and glycerin after each handwashing — wear protective gloves when doing household chores and outdoors in cold weather — avoid scented liquid soaps — soak your hands in vegetable oil (sweet almond, coconut) followed by a cotton glove at night for persistent cases
- Consult a dermatologist or doctor if: deep, bleeding cracks — secondary infection (redness, warmth, pus) — recurring chapping despite proper care — chapping associated with patches or lesions suggestive of eczema or psoriasis
