Is Aloe Vera effective in helping to moisturize dry skin?

# data[].attributes.body
We randomly selected 150 men and women with dry skin. All new to going to a dermatologist for their dry skin.

# data[].attributes.body
The experimental units were selected by going to a dermatologist & asking if the clients with dry skin would be willing to participate in the study. The dermatologist provided us with the skin type and those who were willing to participate over a 12 week period.

# data[].attributes.body
The first randomly picked 50 subjects were assigned to use aloe vera moisturizer on their skin twice a day, once in the morning and once at night. The next randomly picked 50 subjects were to use a drug store moisturizer that didn't contain aloe vera, provided by the dermatologist, and to use the same routine as the other group. The last 50 were to use the same regiment but with no moisturizer and just water and face wash. All were to take a video of them doing it with the date and time stamp to ensure that they stuck with the routine over the 12 week period.

The treatment received; with aloe vera, without aloe vera moisturizer, and only water and face wash without any moisturizer.

At the end of the 12 weeks they visited the dermatologist and inspected the skin of each individual. Also showed their videos to ensure they stuck with the routine.

The control group was the people without moisturizer who just used water and face wash. The placebo groups were the ones with a moisturizer, we didn't tell them if there was or wasn't aloe in the moisturizer.

# data[].attributes.body
This was a blinding experiment because two of the groups didn't know if they had aloe vera or not in their moisturizer.

We randomized the dermatologist office/person and randomized the people who received what moisturizer or no moisturizer. Some lurking variables can include; weather. temperature of the house or water used, type of face wash used, and food or water intake/type.

# data[].attributes.body
Sample size is 150, margin of error was 8.2%. Due to the margin of error being so low, the results found are more likely to be accurate.

# data[].attributes.body
To replicate this study, we will go to a different dermatologist/dermatology office and randomize 150 new subjects with dry skin. We may try a different moisturizer without aloe vera to see if the results change.

# data[].attributes.body
The moisturizer with Aloe Vera was proven to have a better moisturizing outcome on helping dry skin than without the Aloe Vera or just water. Specifically; 40 people found improvements with their skin using the aloe moisturizer whereas only 25 people saw an improvement without the aloe.

# data[].attributes.body
This had a statistical significance due to there being 15 more people with positive results with the aloe compared to without. Out of the 150 subjects 26.6% found improvement with aloe while only 19.3% found improvement without the aloe.

Dermatologists are using more Aloe Vera in their recommended treatment for dry skin due to it's positive results. Also, more companies that sell moisturizer are adding Aloe Vera to their products.
