nificant increase in the mean basal values of
cutaneous blood micro-flow was detected after
the shaving.
New tre a t m e n t: a non significant
decrease in the same parameter was recorded.
The comparison between the variations obtained
after the shaving with the habitual treatment
and with the new treatment showed a statistically
significant difference.
The comparison between the values re c o rd e d
b e f o re the shaving, at the basal control and at the
end of the treatment, resulted non significant.
C onclusion
In order to evaluate the long-term
skin compatibility of the treatment Vi c h y
Homme Sensi-Baume Ca and Mousse à Raser
Anti-Irritations, 30 volunteers, having sensitive
skin, used it for the daily shave for 3 weeks.
Instrumental evaluations of transepidermal
water loss, skin redness and blood micro-flow
were performed on the cheeks, before and 30
minutes after the shaving, at the beginning and
at the end of the period of use.
Those evaluations showed the following re s u l t s :
TEWL: the highly significant increase in the transepidermal
water loss values detected after the
shaving with the habitual treatment indicated a
After habitual shaving After new treatment shaving
Long-term instrumental evaluation of skin compatibility of a shaving treatment for sensitive skin
worsening in skin barrier health. After
the shaving with the new treatment, a
non significant decrease in the same
parameter was detected. Furthermore ,
the comparison between the habitual
and the new treatment was highly
significant. These results indicate that
the shaving with the new tre a t m e n t
p re s e rved the barrier health and the
integrity of the skin.
The comparison between the TEWL
values recorded before the shaving,
at the basal control and at the end of
the study, showed a statistically significant
decrease in the values. This
indicated that the new treatment is also effective
in protecting and strengthening the skin
after a long-term use.
Cutaneous colorimetry and blood micro-flow: a
statistically significant increase in the skin redness
and in blood micro-flow values was detected
after the shaving with the habitual treatment.
No significant variation in the same parameters
was instead detected after the shaving
with the new treatment.
The comparison between the habitual and the
new treatment was statistically significant.
These results showed that the new treatment is
effective in preventing the onset of skin irritations
after the shaving (Figure 4).
