The Benefits and Uses of Lanolin, Backed by Science

Benefits and Uses of Lanolin

Lanolin is a waxy substance that sheep naturally produce to protect their wool. Because lanolin’s properties are similar to those of the sebum (oil) secreted by human skin, it is a popular ingredient in moisturizers, hair care products, and soaps. It is also widely promoted as a natural remedy for sore nipples due to breastfeeding.

Benefits and Uses of Lanolin

Lanolin is classified as an occlusive moisturizer. This means it works by reducing water loss from the skin, similar to petroleum jelly. While petroleum can reduce the evaporation of skin’s moisture by 98%, lanolin reduces it by between 20% and 30%. However, many people like that lanolin isn’t as heavy as petroleum jelly, making it more pleasant to use.

In skincare products, there’s no hard evidence showing lanolin is better than synthetic waxes. If you like using natural products, though, you may prefer lanolin over synthetics.

Lanolin is in a wide variety of over-the-counter (OTC) products.

Breastfeeding and Sore Nipples

During breastfeeding, your nipples may become sore, dry, and even cracked. Many healthcare providers recommend lanolin creams to ease nipple pain from breastfeeding.

A big benefit is that it’s generally considered safe for your baby to ingest small amounts of lanolin. It’s recommended that you use it at least 10 minutes before you start breastfeeding. But unlike other products, you don’t need to wipe it off.

Dry Lips

Lanolin is used in lip balms for moisturizing, with a variety of over-the-counter options available.

Wrinkles

Sometimes used in anti-aging products, some believe lanolin makes wrinkles appear less defined. Moisturizers that include the substance are said to work by plumping the skin after application, temporarily making wrinkles less pronounced.

Risks

If you’re allergic to wool, you’re especially likely to be allergic to lanolin, so it’s probably safest to avoid it. If severe symptoms develop, call 911. Be ready to provide critical information like age, height, weight, and the product that caused the reaction.

How Lanolin Products Are Made

The skin of mammals has natural oils that are produced by sebaceous glands. In sheep, these glands secrete lanolin, which keeps their wool soft, moisturized, and protected from outside elements.

To extract lanolin for commercial use, raw wool is either treated with a soap solution or kneaded in hot water. A centrifuge then isolates the lanolin. Further processing includes bleaching, deodorizing, and drying. This does not harm the animal.

The industrial processing of raw lanolin transforms it into a product called Lansinoh. Lansinoh is virtually free of pesticides, detergents, and natural alcohols. It’s less allergenic than raw lanolin, making it more appealing for widespread use.

Structure and Composition

Lanolin differs slightly from human sebum because it does not contain any triglycerides. On a molecular level, the majority of lanolin is made up of alcohols and acids. These compounds combine to form structures known as esters, diesters, and high-molecular-weight hydroxy esters.

Conclusion

Lanolin is a natural moisturizing wax that’s extracted from sheep’s wool. It’s used in a wide array of skincare products, from eye creams to baby oil and hemorrhoid ointment. It’s often recommended for nipples that are sore from breastfeeding. Eating a lot of lanolin can cause lanolin poisoning. If you’re allergic to wool, you may also be allergic to lanolin.
