Abstract

Systems, devices, and methods for a cosmetic sponge having: a tip portion at one end of the cosmetic sponge; an angled portion, where the tip portion is surrounded by the angled portion; a bulbous portion, where the bulbous portion is disposed proximate a bottom of the cosmetic sponge; and a bottom portion, where the bottom portion is surrounded by the bulbous portion; and a thermochromic pigment in at least a portion of the cosmetic sponge, where the portion of the cosmetic sponge changes from a first color at a first temperature to a second color at a second temperature.

Claims (30)

1. A method comprising:

changing, via a thermochromic pigment in at least a portion of a cosmetic sponge, the portion of the cosmetic sponge from a first color at a first temperature to a second color at a second temperature, wherein a liquid absorbed by the cosmetic sponge is at least at the second temperature thereby signaling the cosmetic sponge is damp;

changing, via the thermochromic pigment, the portion of the cosmetic sponge from the second color to the first color as the cosmetic sponge returns to the first temperature based on passage of a period of time, wherein a color transition serves as a visual indicator to a user that the user needs to dampen the cosmetic sponge; and

applying makeup with the cosmetic sponge while the portion of the cosmetic sponge is the second color, wherein the color transition serves as the visual indicator to the user that the user needs to dampen the cosmetic sponge when the color transition happens at the period of time before a completion of the applying of the makeup.

2. The method of claim 1 , further comprising:

absorbing liquid with the cosmetic sponge.

3. The method of claim 1 further comprising:

absorbing liquid with the cosmetic sponge after applying makeup to remove the makeup from the cosmetic sponge.

4. The method of claim 1 , wherein the cosmetic sponge comprises: a tip portion at one end of the cosmetic sponge, and an angled portion, wherein the tip portion is surrounded by the angled portion; wherein the cosmetic sponge further comprises: a bulbous portion, wherein the bulbous portion is disposed proximate a bottom of the cosmetic sponge; and wherein the cosmetic sponge further comprises: a bottom portion, wherein the bottom portion is surrounded by the bulbous portion.

5. The method of claim 1 further comprising:

providing a visual indication that the cosmetic sponge is ready to be used when the portion of the cosmetic sponge is the second color.

6. The method of claim 1 further comprising:

storing the cosmetic sponge when the portion of the cosmetic sponge is the first color.

7. The method of claim 1 further comprising:

changing the portion of the cosmetic sponge from the second color at the second temperature to a third color at a third temperature.

8. The method of claim 7 , wherein the third temperature is a high temperature for cleaning the cosmetic sponge of at least one of: oil, makeup, and foundation.

9. The method of claim 1 , wherein the first temperature is an ambient temperature and a second temperature is a skin temperature of a user.

10. The method of claim 1 further comprising:

serving as a visual indicator to the user that the user needs to dampen the cosmetic sponge again when the cosmetic sponge begins to change color or changes back to the first color during use.

11. A system comprising:

a thermochromic pigment in at least a portion of a cosmetic sponge, wherein the thermochromic pigment is configured to change the portion of the cosmetic sponge from a first color at a first temperature to a second color at a second temperature in response to absorbing liquid by the cosmetic sponge, wherein the liquid is at least at the second temperature thereby signaling the cosmetic sponge is damp before use;

wherein the portion of the cosmetic sponge having the thermochromic pigment is configured to change from the second color to the first color as the cosmetic sponge returns to the first temperature based on passage of a period of time wherein a color transition serves as a visual indicator to a user that the user needs to dampen the cosmetic sponge; and

wherein the cosmetic sponge is configured to apply makeup while the portion of the cosmetic sponge is the second color, and wherein the color transition serves as the visual indicator to the user that the user needs to dampen the cosmetic sponge when the color transition happens at the period of time before a completion of the applying of the makeup.

12. The system of claim 11 , wherein the cosmetic sponge comprises: a tip portion at one end of the cosmetic sponge, and an angled portion, wherein the tip portion is surrounded by the angled portion; wherein the cosmetic sponge further comprises: a bulbous portion, wherein the bulbous portion is disposed proximate a bottom of the cosmetic sponge; and wherein the cosmetic sponge further comprises: a bottom portion, wherein the bottom portion is surrounded by the bulbous portion.

13. The system of claim 11 , wherein the cosmetic sponge absorbs liquid after applying makeup to remove the makeup from the cosmetic sponge.

14. The system of claim 11 , wherein the cosmetic sponge is stored when the portion of the cosmetic sponge is the first color.

15. The system of claim 11 , wherein the portion of the cosmetic sponge is configured to change from the second color at the second temperature to a third color at a third temperature, and wherein the third temperature is a higher temperature than the second temperature.

16. The system of claim 15 , wherein the third temperature is used for cleaning the cosmetic sponge of at least one of: oil, makeup, and foundation.

17. The system of claim 11 , wherein the first temperature is an ambient temperature and a second temperature is a skin temperature of a user.

18. The system of claim 11 , wherein if the cosmetic sponge begins to change color or changes back to the first color during use it serves as a visual indicator to a user that they need to dampen the cosmetic sponge again.
