Age-based group
the study population was divided into two separate groups by age: 40–50 years, and 50–60 years. the anisotropy levels of these two age groups remained at an average level. thus, it can be concluded that the selection criterion of the 40–60-year age group cannot serve as a predictive value, and that these two age groups constitute a homogeneous class (except for hydration).
Anisotropy-based group the study population was segregated according to the initial anisotropy rate: below and above 30% anisotropy. here, the data demonstrated its most significant
effective value. specifically, patients whose initial anisotropy levels are above 30% (or in other terms, to those who would most benefit from the treatment), showed an excellent rate of improvement (-12 points versus -2.61 points), so a 33% variation versus 11%. therefore, the parameter is validated as a predictor of the treatment efficacy.

Hydration-based group In order to further investigate predictive values for the success of the treatment, a study group based on the initial hydration rate (less than 50%, between 50% and 70%, and above 70% initial hydration) was investigated. For patients with poorly hydrated skin (< 50%), the
treatment was found to improve the hydration values by 4.8 points. conversely, in patients with naturally well-hydrated skin (> 70%), the treatment resulted in significant dehydration of -15 points. In conclusion, 3 weeks after treatment evidenced
a good anti-ageing effect (anisotropy of -24.1%). this progressed into an excellent effect (-33%) provided the treatment group was restricted to women who would benefit the most (anisotropy > 30%). similarly, in women with initially poorly hydrated skin (< 50%), in addition to the anisotropy effect, an impressive hydration effect can be seen. In women with well-hydrated skin, some dehydration is observed. prp repairs more effectively provided there is something to repair.
