Abstract

Disclosed is a composition containing phosphatidylserine as an effective ingredient, and more particularly to a composition containing phosphatidylserine as an effective ingredient for protecting and improving a skin, reinforcing a skin barrier function, suppressing and alleviating an inflammatory response, treating and improving an atopic skin, activating PPAR-a promoting a differentiation of the skin, protecting the skin and preventing and improving skin aging and wrinkle. Accordingly, it is possible to protect and improve the skin from the injury due to the ultraviolet or the external stimulating material such as chemical material and to reinforce and strengthen the skin barrier function using the composition, thereby improving a general skin state.

Claims (32)

1. A method for protecting and improving a skin barrier function of a subject having an atopic skin,

comprising administering to the subject an effective amount of phosphatidylserine that protects and improves skin barrier function in the subject,

wherein the phosphatidylserine activates PPAR-alpha to promote the differentiation of skin keratinocytes in the subject, to suppress and alleviate an inflammatory response due to an external stimulation of the subject's skin, and

the phosphatidylserine improves said atopic skin.

2. The method according to claim 1 , wherein the phosphatidylserine is extracted from vegetable originated lecithin, animal oil and fat or manufactured by a phospholipase D transition reaction with the extracted lecithin or hydrogenated type phosphatidylserine.

3. The method of claim 2 , wherein the vegetable originated lecithin is derived from soybean, corn, or mixtures thereof.

4. The method of claim 2 , wherein the animal oil and fat is derived from egg yolk, milk, fish oil, a brain of an animal, or mixtures thereof.

5. The method according to claim 1 , wherein the phosphatidylserine is transcutaneously or orally administered.

6. A method for suppressing and alleviating an inflammatory response of a subject having an atopic skin,

comprising administering to the subject an effective amount of phosphatidylserine that suppresses and alleviates inflammatory response in the subject,

wherein the phosphatidylserine activates PPAR-alpha to promote the differentiation of skin keratinocytes in the subject, to suppress and alleviate an inflammatory response due to an external stimulation of the subject's skin, and

the phosphatidylserine improves said atopic skin.

7. The method according to claim 6 , wherein the phosphatidylserine is extracted from vegetable originated lecithin, animal oil and fat or manufactured by a phospholipase D transition reaction with the extracted lecithin or hydrogenated type phosphatidylserine.

8. The method of claim 7 , wherein the vegetable originated lecithin is derived from soybean, corn, or mixtures thereof.

9. The method of claim 7 , wherein the animal oil and fat is derived from egg yolk, milk, fish oil, a brain of an animal, or mixtures thereof.

10. The method according to claim 6 , wherein the phosphatidylserine is transcutaneously or orally administered.

11. A method for promoting skin differentiation or protecting skin from ultraviolet irradiation or reactive oxygen species of a subject having an atopic skin,

comprising administering to the subject an effective amount of phosphatidylserine that promotes skin differentiation or protects skin from ultraviolet irradiation or reactive oxygen species in the subject,

wherein the phosphatidylserine activates PPAR-alpha to promote the differentiation of skin keratinocytes in the subject, to suppress and alleviate an inflammatory response due to an external stimulation of the subject's skin, and

the phosphatidylserine improves said atopic skin.

12. The method according to claim 11 , wherein the phosphatidylserine is extracted from vegetable originated lecithin, animal oil and fat or manufactured by a phospholipase D transition reaction with the extracted lecithin or hydrogenated type phosphatidylserine.

13. The method of claim 12 , wherein the vegetable originated lecithin is derived from soybean, corn, or mixtures thereof.

14. The method of claim 12 , wherein the animal oil and fat is derived from egg yolk, milk, fish oil, a brain of an animal, or mixtures thereof.

15. The method according to claim 11 , wherein the phosphatidylserine is transcutaneously or orally administered.

16. A method for treating skin aging and wrinkle due to ultraviolet irradiation or exposure of a subject having an atopic skin,

comprising administering to the subject an effective amount of phosphatidylserine that treats skin aging and wrinkle due to ultraviolet irradiation or exposure in the subject,

wherein the phosphatidylserine activates PPAR-alpha to promote the differentiation of skin keratinocytes in the subject, to suppress and alleviate an inflammatory response due to an external stimulation of the subject's skin, and

the phosphatidylserine improves said atopic skin.

17. The method according to claim 16 , wherein the phosphatidylserine is extracted from vegetable originated lecithin, animal oil and fat or manufactured by a phospholipase D transition reaction with the extracted lecithin or hydrogenated type phosphatidylserine.

18. The method of claim 17 , wherein the vegetable originated lecithin is derived from soybean, corn, or mixtures thereof.

19. The method of claim 17 , wherein the animal oil and fat is derived from egg yolk, milk, fish oil, a brain of an animal, or mixtures thereof.

20. The method according to claim 16 , wherein the phosphatidylserine is transcutaneously or orally administered.
