Best Moisturiser Ingredients for Dry Skin

Why dry skin keeps getting drier

Your skin's outer layer (the stratum corneum) is held together by lipids — ceramides, fatty acids, and cholesterol. When those run low, the barrier develops microscopic gaps. Water escapes through them constantly (called transepidermal water loss, or TEWL), and irritants get in. The result is that familiar tight, rough, sometimes flaky feeling that gets worse in cold or low-humidity environments.

Ingredients that actually rebuild dry skin

The key is to both add moisture and physically seal it in. Look for:

• Ceramides (NP, AP, EOP) — Directly replace the lipids your barrier is missing. The most evidence-based ingredient for genuine barrier repair.
• Squalane — A lightweight plant-derived oil that mimics skin's own sebum. Absorbs without greasiness and prevents moisture loss.
• Shea butter — Rich in oleic and stearic fatty acids. Creates a protective layer that slows TEWL significantly, especially overnight.
• Glycerin (high concentration) — A humectant that draws water into the skin. Works best when layered under an occlusive to trap the moisture.

What to avoid if your skin is dry

Some ingredients sold for "hydration" make dry skin worse over time:

• Alcohol denat. / SD alcohol — Strips the lipid barrier and increases TEWL. Common in "lightweight" gels and toners — check the label.
• Fragrance and essential oils — Sensitise an already-compromised barrier. Fragrance-free is non-negotiable for chronically dry skin.
• Salicylic acid cleansers — Designed to remove oil and dead cells — exactly what dry skin doesn't have to spare.

The routine tip most dry skin types miss

Apply your moisturiser to slightly damp skin — within 60 seconds of washing your face or spraying a facial mist. The occlusive ingredients in a good moisturiser will then trap ambient moisture against the skin rather than pulling it back out. In very dry climates, skip the mist and go straight to a ceramide cream to avoid the mist evaporating and taking skin moisture with it.
