The

Lipstick

Challenge

2 of 11

Purpose:

I choose this experiment is to see which long lasting lipstick stands up to the test of lasting all day. These three lipsticks will be put to the test: Santorini Long Lasting Liquid Lipstick, Stila Stay All Day Liquid Lipstick, and LipSense by SeneGence Long Lasting Liquid Lip Color. I got help from my mom and learned more about how long lipstick can last.

Hypothesis:

If I test three lipsticks (Santorini Long Lasting Liquid Lipstick, Stila Stay All Day Liquid Lipstick, LipSense by SeneGence Long Lasting Liquid Lip Color) that claim they stay all day, then I predict that the LipSense by SeneGence Long Lasting Liquid Lip Color will last the longest.

Procedures:

The steps to doing my experiment are:

  • Gather all materials.
  • Use the wands from the lipstick containers to wipe each lipstick next to each other on top of the hand one time being sure not to overlap lipsticks.
  • Label the lipsticks 1, 2, 3 on the top of the hand,
  • Blot hand with clean copy paper immediately after applying lipsticks.
  • Label copy paper to match the numbers on the hand.
  • Blot hand with copy paper each hour until the lipstick is faded or disappears. Add numbers 1, 2, 3 above each blot.
  • Record all data after each blot.
  • Continue experiment over the next two days following the above steps.

Data:

The LipSense Long Lasting Liquid Lip Color stayed on the longest with little fading and no chipping for 8 hours. Next was the Stila. The Stila started to fade away after 5 hours of wear. The lipstick that stayed on the least was the Santorini. It faded after 4 hours of wear. Both the Stila and the Santorini continued to smear after each blot. The LipSense never smeared and never showed any fading while being blotted.

Conclusion:

The LipSense Long Lasting Liquid Lip Color is the best if you are looking for all day wear without fading or smearing. My prediction was correct, the LipSense lasted the longest at 8 hours. Stila Stay All Day Liquid Lipstick came in as the second best lipstick to use. Although there was continuous smearing when blotted it lasted for 5 hours of wear. Last was the Santorini Long Lasting Liquid Lipstick. It also had continuous fading and smearing and lasted for 4 hours of wear.

Real Life

Connection:

This project relates to real life because when someone puts on lipstick they want it to last and stay on a long time. My project can help people that wear lipstick and want it to last all day.

to Math:

In this project math was used to calculate how long the lipstick lasted by using a clock and telling time to the hour.
