Body Lotion — What Should a Good Moisturiser Contain?
How do body lotion, butter and oil differ? Discover the key moisturising ingredients — glycerin, urea, shea butter and squalane — and pick the right product.
Body moisturising — why does it matter so much?
The skin on your body is thinner and has fewer sebaceous glands than facial skin, which means it loses moisture more easily. Regular moisturising not only improves the comfort and appearance of your skin, it also supports its barrier function — the skin's natural defence against external factors, pathogens and water loss.
Choosing the right product depends on your skin type, the season and personal preference. In this article we break down what goes into body lotions and show you which ingredients to look for on the INCI list.
Lotion, butter, oil — what's the difference?
Body lotion
An oil-in-water (O/W) emulsion. It has a light texture, absorbs quickly and leaves no greasy film. Ideal for everyday use, especially in summer. Its high water content makes it less occlusive than a butter.
Body butter
A rich emulsion or anhydrous formula with a high content of plant fats (shea, cocoa or mango butter). Strongly occlusive — it forms a layer that prevents water loss. Best for winter and very dry skin.
Body oil
An anhydrous formula based on plant or mineral oils. It contains no humectants (unless it's a “dry oil” version). It seals the barrier beautifully but doesn't deliver water to the skin — which is why it's best applied to damp skin after a bath.
Key moisturising ingredients
Humectants — they attract water
- Glycerin — one of the most thoroughly researched humectants. It draws water from deeper skin layers and from the surrounding air, keeping the epidermis hydrated. Effective even at a 3–5% concentration.
- Urea — a natural component of the NMF (Natural Moisturizing Factor). At 5–10% it moisturises; at higher concentrations it exfoliates. Ideal for dry, rough skin.
- Hyaluronic acid (Sodium Hyaluronate) — popular in facial creams and increasingly added to body lotions. It binds water within the epidermis.
- Sorbitol, Propylene Glycol — additional humectants that support hydration.
Emollients — they smooth and soften
- Shea butter (Butyrospermum Parkii Butter) — rich in fatty acids and phytosterols. It smooths, nourishes and soothes irritation.
- Squalane — a lightweight, non-comedogenic emollient similar to the skin's natural sebum. It absorbs quickly.
- Jojoba oil (Simmondsia Chinensis Oil) — technically a liquid wax, exceptionally well tolerated by the skin.
- Caprylic/Capric Triglyceride — light emollients that improve how the product spreads.
Occlusives — they lock in water
- Petrolatum — the most effective occlusive, reducing TEWL (transepidermal water loss) by up to 98%. Safe and well researched, though not everyone likes its texture.
- Dimethicone — a silicone that forms a breathable protective layer. It doesn't clog pores.
- Ceramides (Ceramide NP, AP, EOP) — natural lipids that build the skin barrier. In lotions they help rebuild a damaged barrier.

Moisturising and the seasons
Your skin's needs change with the seasons:
- Winter: low humidity and central heating cause intense water loss. Reach for richer formulas with shea butter, ceramides and petrolatum. A body butter works better than a light lotion.
- Summer: a light lotion based on glycerin and squalane is enough. Avoid heavy occlusives, which can feel sticky in the heat.
- Spring/autumn transition: a moderately rich lotion with urea and jojoba oil is a good compromise.
Fast absorption vs. strong occlusion
This is consumers' most common dilemma. Fast-absorbing products (based on light emollients and humectants) are convenient for daily use but don't form a strong protective layer. Occlusive products (with petrolatum, butters and waxes) last longer but take time to sink in.
The solution? The “layering” technique: apply a light, humectant-rich lotion to damp skin, then add an occlusive butter or oil to particularly dry areas (elbows, knees, shins).
What to watch out for in the ingredients?
- Parfum high on the INCI list — strong fragrance blends can irritate, especially skin that has just been shaved or waxed.
- Alcohol denat. — rarely found in body lotions, but drying.
- No humectants — an oil on its own, without glycerin or urea, doesn't moisturise; it merely seals. A complete formula combines humectants with emollients.
If you're wondering whether “natural” ingredients are better than synthetic ones, it's worth reading our guide to natural and synthetic ingredients.
Practical tips
- Apply lotion within 3 minutes of bathing, to damp skin — this maximises hydration.
- Match the texture to the season and your skin's needs.
- Look for glycerin, urea or hyaluronic acid in the first half of the INCI list.
- For very dry skin, choose products with ceramides and shea butter.
- Pair gentle shower gels with moisturising — cleansing and care are the two pillars of healthy skin.
FAQ
It's not recommended. Body lotions often have heavier formulas and intense fragrance blends that can irritate the more delicate skin on the face. It's better to use dedicated facial creams.
A lotion is a light, fast-absorbing oil-in-water emulsion. Body butter has a thicker texture with a higher content of plant fats and stronger occlusive action. Butter works better in winter and on very dry skin.
Yes. Cosmetic petrolatum is one of the most thoroughly researched occlusive ingredients. It doesn't absorb into the skin but forms a protective layer that reduces water loss. It is safe and well tolerated.
Ideally, every day after bathing. People with dry skin or during the heating season can apply lotion even twice a day. The key is to apply it to damp skin, which improves the absorption of humectants.
