Does lanolin clog pores?

What does a clogged pore look like?

Clogged pores form when debris blocks a hair follicle and its oil duct. The resulting bumps are called comedones: blackheads are open comedones, while whiteheads are closed comedones with a completely blocked follicle. Comedonal acne often affects the forehead and chin. Inflammation also plays a part, so pore blockage is not simply a cosmetic product sitting on top of the skin. Increased oil production and changes in the cells lining the follicle help create the blockage.3

Should you avoid lanolin in face products?

If you already have acne or frequent clogged pores, a product without lanolin is a reasonable cautious choice. Certain moisturizers, foundation and hair pomades can worsen acne, and lanolin is among the ingredients to watch for. Acne also involves factors such as hormones and genetics, so finding lanolin on an ingredient list is not enough to identify the cause of every new spot. Consider the product alongside the rest of your routine rather than treating one ingredient as the whole explanation.1

Products labeled "noncomedogenic" are intended not to clog pores and do not cause breakouts in most people, which is more useful than a jar making vague promises about perfection. Include makeup, sunscreen and hair products when reviewing your routine. Skin care and hair care both belong on the product checklist, even if the hair products would prefer not to attend.2

What should you do if you suspect your moisturizer?

1. 1Replace the suspected product with a moisturizer made for skin prone to acne and labeled "noncomedogenic" or "won't clog pores."
2. 2Wash gently with a mild cleanser when you wake up and before bed, and after sweating. Do not scrub or repeatedly wash to remove a suspected pore clogging ingredient.
3. 3Apply the replacement moisturizer after washing, twice daily if your skin feels dry. Trying to dry out acne can irritate skin and lead to more breakouts.
4. 4Keep using acne medication as directed. Do not switch acne treatments every week while trying to work out whether a moisturizer is contributing.

Lanolin allergy is a separate concern

Lanolin can cause allergic contact dermatitis, an allergic skin reaction after contact with a substance. Personal care products and medications are common sources of lanolin exposure. People with lanolin allergy were more likely to have a history of eczema or hay fever than people without the allergy in a large group undergoing patch testing. If you have a known lanolin allergy, avoid products containing it. If a lanolin product causes a rash, stop using it and seek medical advice rather than assuming the reaction is clogged pores.4

How long should clearing take?

There is no set countdown for clearing after removing a lanolin product. For acne treatment, expect at least 6 to 8 weeks before seeing fewer breakouts; comedonal acne can take several weeks to months to improve. Those are treatment timelines, not a test for whether lanolin caused the problem. Removing a suspected product and treating existing acne are separate steps. Retinoids, salicylic acid and azelaic acid are treatments that help clear clogged pores.35

See a dermatologist for deep or painful acne, or persistent breakouts despite appropriate skin care and treatment. Some conditions resemble acne but need different treatment. A dermatologist can identify whether the bumps are acne and choose treatment for the type of breakouts you have, rather than relying on ingredient elimination alone.25
