What it does
- Softens and deeply conditions very dry, chapped skin and lips.
- Occlusive — helps reduce water loss.
- Structurally similar to the skin's own surface lipids.
How it works
Lanolin is widely documented as an emollient and occlusive whose composition resembles human skin lipids, making it exceptional for chapped skin, lips and nipple care. Modern purified grades reduce impurities, but lanolin can still be a contact allergen for some.
Use level
- Typical use level
- variable; commonly 1–10% (higher in balms)
Commonly used at 1–10% in creams and higher in balms; use purified cosmetic grades.
Formulation considerations
- Oil-soluble/waxy; melt into the oil phase.
- Rich, sticky feel — balance with lighter emollients.
- Can be a contact allergen for some; patch-testing advised.
What it pairs with & what to avoid
Pairs well with
- Lighter emollients (to balance feel)
- Occlusives and butters
Use with care / avoid
- Contact-allergy potential in sensitive users
Regulatory status
Lanolin is listed in the EU CosIng database; purified cosmetic grades are long-established emollients.
