Lips Repair Act
Repairing Lip Balm
Immediate Skin Hydration Evaluation
The short-term skin hydration increased by 17.4% after 15 minutes and 14.8% after 30 minutes by using the product (statistically significant result).
Evaluation of Immediate Protective Activity
In order to determine the protective activity of Lips REPAIR ACT, the forearm of each volunteer was divided into two zones: treated area on which the balm was applied; untreated area on which the product was not applied. On both areas it was subsequently applied a patch with a slightly irritating solution that was removed after 20 minutes.
The treated area with Lips REPAIR ACT, after removing the irritating patch, showed an increase of Skin Redness in only 30% of volunteers, compared with 100% of the volunteers in the non-treated area. Data indicate a product protective effect confirmed also by the value of the Skin Redness that was 1.85 in the treated area with Lips REPAIR ACT and 3.65 in the untreated area (average values).
Evaluation of Immediate Soothing Activity
For the determination of the soothing activity, the forearm of each volunteer was divided into two zones and it was applied a patch with a slightly irritating solution. After 20 minutes, the patch was removed. Lips REPAIR ACT was applied on a area (treated area) while on the other (untreated area) was not applied the product. On both areas the following parameters have been detected: Erythema index, TEWL and Skin Redness, which were also monitored after 30 minutes and 1 hour after removal of the patch.
The treated area with Lips REPAIR ACT LIPS had a skin redness reduction after 30 minutes and after 1 hour the product application.
The redness reduction was detected by the dermatologist in 100% of volunteers after 1 hour from the application of the product.
In the treated area with Lips REPAIR ACT, the erythema value decreased by 6% after 30 minutes of patch removal of the patch (statistically significant reduction) and by 12% after 1 hour of patch removal (statistically significant).
In the treated area with Lips REPAIR ACT, the TEWL value has decreased by 23% after 30 minutes and by 40% after 1 hour of product application (statistically significant). A reduction of TEWL proves a better skin condition and a moisturizing action of the product.
Subjective evaluation (Self-evaluation)
Percentage of subjects who expressed a positive opinion for the following parameters:
Replying to the question “In case of chapped lips, how many days your lips are back to normal?” voluntaries said from 1 day (minimum time) to 8 days (maximum time) the period in which the lips were back to normality (average value 3.9 days).
