How to choose a moisturizer for combination skin

Does every part of your face need moisturizer?

Combination skin means some areas are dry while others are oily. The oily areas often include the forehead, nose and chin, known as the T zone. Treat those areas separately: moisturize dry patches and leave oily areas without moisturizer if they do not need it. A lotion is a useful starting point, not a contract requiring identical treatment for every square inch.2

Should you choose a gel, lotion or cream?

Occlusive means forming a barrier that slows water escaping from the skin. An ointment gives a longer lasting protective layer, but can feel greasy; a cream absorbs more quickly and needs more frequent application. Choose the texture for the patch you are treating, not just the skin type printed on the box.3

What should you look for on the label?

Look for fragrance free and noncomedogenic, meaning formulated not to clog pores. Ceramides, hyaluronic acid and dimethicone are useful ingredients to look for in a facial moisturizer. Dimethicone can also form a barrier that helps reduce irritation. These are selection criteria, not a reason to choose the product with the longest ingredient list.1

A moisturizer can combine several jobs. Humectants, such as glycerin, attract and retain water. Emollients soften and smooth the outer skin layer. Occlusives, such as dimethicone or petroleum jelly, reduce water loss. Some moisturizer marketing claims about skin aging are misleading, so the packaging is not a reliable crystal ball.3

Is niacinamide useful for combination skin?

Niacinamide is a form of vitamin B3 found in some moisturizers. It may help regulate oil production, making it a useful option when oiliness is part of the problem. It may also support the skin barrier, the protective outer layer that helps retain moisture and keep irritants out. Consider it an optional ingredient rather than the deciding factor: the moisturizer's texture and how well you tolerate it still matter.4

Most skincare products contain 5% niacinamide or less, although amounts vary. Start with a low concentration if your skin is sensitive. Niacinamide is generally gentle, but can cause itching, redness, mild burning or an allergic reaction. If you are concerned about a reaction, test a small amount on your forearm and wait 24 hours. Avoid stacking several products containing niacinamide at once.4

How to apply your moisturizer

1. 1Wash your face with a mild, fragrance free cleanser.
2. 2Apply moisturizer immediately after washing. After a shower, gently pat your skin dry and moisturize while it is still damp to help trap water.
3. 3Apply moisturizer to dry areas. Skip oily areas that do not need it, or choose a lighter gel for those areas.
4. 4During the day, include broad spectrum sunscreen with SPF 30 or higher, along with shade and protective clothing when appropriate.

How often should you moisturize?

Let the amount of dryness guide the frequency. Slightly dry skin can need only a light moisturizer at night; very dry areas need more frequent application. Moisturizers reduce dryness and support the skin barrier, but their therapeutic effects are greatest in the first six hours after application. Regular application two to three times daily can be needed to maximize benefits, rather than expecting one application to last indefinitely.3

Should your moisturizer change with the weather?

Cold weather and indoor heating reduce moisture in the air, making dry areas harder to keep comfortable. Use a thicker moisturizer on exposed dry skin before going outside in cold, windy conditions, and reapply as needed. Hot, humid weather can make a gel a better fit. A seasonal texture change is practical; your moisturizer does not need a permanent position in the bathroom.15

What if your dry patches keep getting worse?

Do not respond to every flake by exfoliating. Exfoliation removes moisture and oils and can make dry skin itchier. Harsh astringents, scented cleansers and excessive scrubbing can also worsen dryness. Retinol and acne ingredients such as salicylic acid or benzoyl peroxide can be drying, especially in winter. If you use a prescribed treatment, discuss irritation with your dermatologist rather than replacing the treatment plan with a richer moisturizer.15

When should you stop or see a dermatologist?

Heavy occlusive moisturizers can cause or worsen acne. Urea and acidic preparations can sting scratched or cracked skin. Stop a moisturizer if contact dermatitis develops, meaning an irritated or allergic skin reaction; a dermatologist can investigate suspected allergy with patch testing.3

If dry areas remain troublesome, use a fragrance free cleanser and a noncomedogenic moisturizer you can comfortably apply at least twice daily. Make a dermatologist appointment if that does not help, or if dryness becomes painful, cracked, bleeding, stinging or very irritating. Persistent symptoms can need a prescription rather than another moisturizer purchase.2
