Abstract

Described herein are personalized skin care compositions including a cultured composition including a milk sample and a skin sample. and optionally an additive. Also described herein are kits and methods for making personalized skin care compositions. Also described herein are methods of treating or preventing skin conditions using personalized skin care compositions.

First claim

What is claimed is:

1 . A personalized skin care composition comprising:
a cultured composition comprising:
a milk sample acquired from breast milk or baby formula; and
a skin sample acquired from a healthy skin area of a subject; and
optionally an additive.

2 . The personalized skin care composition of claim 1 , wherein the cultured composition is cultured for an amount of time greater than about 24 hours.

3 . The personalized skin care composition of claim 1 , wherein the cultured composition is cultured at a temperature greater than about 18° C. and less than about 30° C.

4 . The personalized skin care composition of claim 1 , wherein the subject is a child.

5 . The personalized skin care composition of claim 1 , wherein the baby formula comprises a component selected from the group consisting of human milk oligosaccharides, prebiotics, probiotics, and combinations thereof.

6 . A kit for making a personalized skin care composition, the kit comprising:
a sterile implement; a sterile collection vial; a sterile, hydrophobic container comprising etching for biofilm formation, a lid, and a filter allowing for gas exchange; optionally a breast pump; and written instructions for making the personalized skin care composition, comprising the method steps of:
i. acquiring a milk sample from breast milk or baby formula using the sterile collection vial and optionally the breast pump;
ii. acquiring a skin sample from a healthy skin area of a subject using the sterile implement;
iii. transferring the milk sample to the sterile, hydrophobic container and mixing the milk sample and the skin sample; and
iv. culturing the milk sample and the skin sample to yield the personalized skin care composition.

7 . The kit of claim 6 , wherein the method step of culturing the milk sample and the skin sample forms a biofilm.

8 . The kit of claim 6 , wherein the method step of culturing the milk sample and the skin sample is carried out at a temperature greater than about 18° C. and less than about 30° C.

9 . The kit of claim 6 , wherein the method step of culturing the milk sample and skin sample is carried out for an amount of time greater than about 24 hours.

10 . The kit of claim 6 , wherein the subject is a child.

11 . A method of making a personalized skin care composition, the method comprising:
acquiring a milk sample from breast milk or baby formula; acquiring a skin sample from a healthy skin area of a subject; mixing the milk sample and the skin sample; and culturing the milk sample and the skin sample to yield the personalized skin care composition.

12 . The method of claim 11 , wherein the method step of culturing the milk sample and the skin sample comprises forming a biofilm.

13 . The method of claim 11 , wherein the method step of culturing the milk sample and the skin sample is carried out at a temperature greater than about 18° C. and less than about 30° C.

14 . The method of claim 11 , wherein the method step of culturing the milk sample and skin sample is carried out for an amount of time greater than about 24 hours.

15 . The method of claim 11 , wherein the subject is a child.

16 . A method of treating or preventing a skin condition in a skin area in need thereof, the method comprising:
acquiring a milk sample from breast milk or baby formula; acquiring a skin sample from a healthy skin area of a subject; mixing the milk sample with the skin sample; culturing the milk sample and skin sample to yield a personalized skin care composition; and applying an effective amount of the personalized skin care composition to the skin area in need thereof of the subject.

17 . The method of claim 16 , wherein the method step of culturing the milk sample and the skin sample comprises forming a biofilm.

18 . The method of claim 17 , further comprising a step of applying the biofilm to the skin area in need thereof.

19 . The method of claim 16 , wherein the skin condition is diaper rash.

20 . The method of claim 16 , wherein the healthy skin area is a perianal skin area.
