Ingredient review
Lanolin
INCI: LANOLIN
Lanolin is a time-tested moisturizer that mimics skin's natural oils, but it can be comedogenic for some and is not suitable for those with wool allergies.
In plain English
Lanolin is a waxy substance that comes from sheep's wool. It's very similar to the oils our own skin produces, so it's great at softening and protecting dry skin. You'll find it in many lip balms, hand creams, and baby products. However, because it's thick and can clog pores, it may cause breakouts in acne-prone people. Also, if you're allergic to wool, you might react to lanolin.

Quick decision guide
Useful, but context matters
Lanolin can be useful, but watch for possible clogging concerns.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Lanolin.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.

strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
Lanolin is a natural, waxy substance secreted by the sebaceous glands of sheep to condition and protect their wool. It is refined and purified for use in cosmetics and skincare products.
How it works
Lanolin works as both an emollient (softens skin) and an occlusive (forms a protective layer on the skin's surface to prevent water loss). It helps restore the skin's natural barrier, keeping moisture in and irritants out.
Pros
Excellent moisturizer
Lanolin is highly effective at softening and hydrating very dry, cracked skin, making it a go-to for chapped lips and rough hands.
Protective barrier
Its occlusive nature helps seal in moisture and protect skin from environmental stressors, which is especially helpful in harsh weather.
Cons and cautions
May clog pores
Lanolin has a moderate comedogenic rating, meaning it can cause breakouts or milia in people with acne-prone or oily skin.
Allergen potential
A small percentage of people are allergic to lanolin, especially those with wool allergies, leading to contact dermatitis or irritation.
Best for
- People with very dry, rough, or chapped skin
- Those looking for a rich, protective moisturizer for hands, lips, or feet
Use caution if
- Individuals with known wool or lanolin allergies
- Acne-prone or oily skin types (may clog pores)
Usage tips
Safety summary
Lanolin is considered safe for most people when used as directed. The main risks are allergic reactions in wool-sensitive individuals and potential pore-clogging in acne-prone skin. Refined, hypoallergenic grades reduce but do not eliminate these risks.
Research notes
Multiple studies support lanolin's effectiveness as a moisturizer and barrier repair agent. It is widely used in dermatology for dry skin conditions. Allergic reactions are documented but uncommon, affecting an estimated 1–3% of the population.
