Independent Appraisal


The purpose of this survey was to evaluate the usefulness of Baby Foot in the removal of old keratin from the sole, subsequent sole skin care as well as its safety of use.


Survey Period: 12th-26th Aug 2009
Methods: As monitors, we selected 30 healthy adults aged 25 to 59 years (12 males, 18 females), to examine the condition of the sole. At first, the physician evaluated the sole of the monitor and measured the hardness of the heel region before using Baby Foot. The test product was used at night time on the same day. After 2 weeks of follow-up at each monitor’s home, final measurement involving physician’s evaluation (measurement of the hardness of the heel region) was conducted.

Before Baby Foot

Neither the thickness of dead skin of the sole nor dryness required treatment or was painful in any monitor. In approximately 50% of the monitors, treatment was not necessary.

After Baby Foot

・ Changes in the Sole Condition

The changes in the sole condition within 2 weeks after the start of Baby Foot usage in a representative monitor are shown below.

Changes in the Sole Condition

The lotion of Baby Foot contains fruit acid, which penetrates the accumulated, old skin layers, acting on the adhesive area between older and newer skin layers and promoting the exfoliation of the old dead skin cell layers. The result of this survey showed that Baby Foot supported the removal of the dead skin cells and that it might improve the sole condition via this mechanism.

Changes in the degree of keratin exfoliation of the sole in all monitors

Thus, the use of Baby Foot promoted the removal of the dead skin cell layers of the sole, improving the sole condition to a healthy state after 2 weeks.

After Baby Foot

・ Comparison of the hardness of keratin of the sole before and after use

 Changes in the thickness of the sole
    (based on the measurement of hardness of the heel region and palpation findings)

Changes in the thickness of the keratin of the soleNumbers
Very Soft 10 33.3
Soft 10 63.3
Slightly Soft 1 3.3
Slightly Hard 0 0.0
Hard 0 0.0
Very Hard 0 0.0

The dead skin cells of the sole became soft in all monitors, suggesting that Baby Foot is useful for softening the keratin of the sole.

Comparison of the appearance of the sole

Based on visual inspection/palpation, the keratin condition became "Good/Slightly Good" in all monitors and a good, smooth and health sole condition was achieved in 70% of results.

・ Example

Initial Measurement Final Measurement

Apparent changes of the soleNumbers
Good/Smooth 21 70.0
Slightly Good but Partially Thick 9 30.0
Thick 0 0.0
Very Thick/Tough 0 0.0

These results showed that the use of the test product improved the appearance on the sole and keratin condition to a healthy state in comparison with those before use.

Safety of Baby Foot

There were no irritative symptoms after use and Baby Foot contributed to the exfoliation of old keratin. During this process, however, no monitor complained of pain or discomfort. Neither side effects such as contact dermatitis nor abnormal findings were observed, suggesting the safety of the product. Considering the monitor’s initial sole conditions, most monitors did not require treatment. However, even in these monitors, "Moderate Improvement" or better was achieved without side effects, suggesting that Baby Foot is available not only for keratin control of the sole, but also for daily sole care.


The results of this survey suggest that Baby Foot improves the sole condition by promoting the removal of old keratin of the sole without causing side effects.
