Sea buckthorn oil is used in cosmetics, dietary supplements, nutraceuticals, and skin care products. Russian and Asian traditional medicines have used sea buckthorn oil for skin for centuries. Even some dietary supplement products contain this oil. There is some confusion about sea buckthorn seed oil and berry oil. Both the oils come from the sea buckthorn berry and they have many similarities, they do have a lot of differences too. Seed oil has omega 3 and 6, and a lot of vitamin E. These are all great for skin. However, it does not contain omega 7, which is required for healing skin tissues. The berry oil contains the omega 7. When taken internally, it can help the gastrointestinal tract to soothe stomach ulcers and acid reflux. All in all, both have skin-friendly properties and you should use sea buckthorn oil for skin.
