Symptoms and context
True dry skin is structurally short on lipids — it feels tight, can flake or scale, and is prone to fine surface lines. Dehydrated skin lacks water, which can affect any skin type; it feels tight after cleansing but may still be oily. Most "dry skin" complaints are a mix.
Common causes
- Constitutional / genetic lipid profile.
- Aging — sebaceous and lipid output decline.
- Over-cleansing or surfactant-heavy cleansers.
- Indoor heating, low humidity, wind exposure.
- Filaggrin mutations (eczema-related).
- Medications: retinoids, isotretinoin, some antihistamines, diuretics.
Routine principles
- Hydrate, then seal. Humectants pull water in; occlusives keep it there.
- Apply moisturizer to damp skin.
- Don't strip. Cream or oil cleansers, lukewarm water.
- Layer thin-to-thick. Essence/serum → moisturizer → balm where needed.
Morning routine
- Cream or non-foaming cleanser, or water rinse only.
- Hyaluronic acid + glycerin essence on damp skin.
- Ceramide-rich moisturizer.
- SPF 30+ in a cream base, not gel.
Evening routine
- Oil or balm first cleanse → cream cleanser if needed.
- Humectant essence.
- Optional treatment serum (peptides, niacinamide, retinoid 2–3x/week).
- Ceramide-rich cream + occlusive (squalane or petrolatum) over very dry spots.
Ingredients to prioritize
- Humectants — glycerin, hyaluronic acid, urea, panthenol, sodium PCA.
- Emollients — squalane, jojoba, shea butter, fatty alcohols.
- Occlusives — petrolatum, dimethicone, beeswax, mineral oil.
- Ceramides + cholesterol + fatty acids in physiologic ratio.
- Niacinamide for endogenous ceramide synthesis.
Ingredients to use carefully
- High-strength AHAs more than 2x/week.
- Sulfate cleansers, especially SLS.
- Alcohol denat-heavy toners.
- Hot water and long showers.

When to see a professional
- Persistent flaking with itching — could be eczema, seborrheic dermatitis, or contact allergy.
- Crusting, oozing, or worsening despite gentle care.
- Sudden dryness alongside fatigue, hair loss, or weight changes — could be thyroid related.
