Body lotion vs body oil: Which should you use?

What is the difference?

Body oil and body lotion are both moisturizers, despite the bottles behaving as though they belong to rival departments. Moisturizers work through humectants, which attract water, emollients, which soften skin, and occlusives, which form a film that slows water loss. One ingredient can do more than one job. The actual formula matters more than whether the front says lotion or oil.14

Which should you choose?

• For mild dryness, start with lotion, especially if greasy products feel uncomfortable under clothing.
• For rough, persistently dry skin, choose a cream or ointment. Look for ingredients such as glycerin, hyaluronic acid, mineral oil, petrolatum or shea butter.
• For sensitive skin, choose a fragrance free formula and avoid botanical ingredients that you know cause reactions. Fragrance free does not mean free of every allergen.
• For body areas prone to acne, look for a moisturizer labelled noncomedogenic, meaning unlikely to clog pores. Oily, occlusive products can aggravate acne or inflamed hair follicles.

A more expensive bottle is not necessarily more effective, even if the packaging has dressed for a promotion. Compare the ingredients and the texture you will actually use rather than treating price as a measure of moisturizing power.2

How do you use body oil and lotion together?

You can use lotion without adding oil, so the bathroom shelf does not need a second shift. If you want both, use lotion as your main moisturizer and oil as an optional finishing layer; this is a general layering approach, while individual product directions take priority.13

1. 1Keep your shower lukewarm and short, about five to ten minutes.
2. 2Pat your skin until it is no longer dripping, leaving it slightly damp.
3. 3Apply lotion within three minutes. Smooth it gently in the direction your hair grows rather than rubbing vigorously.
4. 4If adding oil, smooth it over the areas where you want an additional moisture retaining layer.

Moisturize after every bath or shower and reapply when skin feels dry or tight. Morning versus evening matters less than applying after washing. Slightly dry skin can need only a light moisturizer at night; eczema often needs generous application two to three times daily, continued even when skin feels comfortable.1456

When should you change products or get help?

Stop a product that causes a new rash. Ask a pharmacist or doctor about persistent burning, stinging or inflamed hair follicles. If a suitable moisturizer and gentler washing routine do not improve dryness, see a healthcare professional. When using a prescribed skin treatment, leave 20 to 30 minutes between it and your moisturizer, and ask your doctor which goes first.456

Oil and other moisturizers can make bathroom surfaces slippery. Keep clothing and bedding carrying moisturizer residue away from flames and cigarettes; the fire risk applies to emollients with or without paraffin.16
