Clinical examination of the polysaccharide blend on skin barrier recovery from tape stripping A blinded clinical study was undertaken to examine in vivo the effects of the polysaccharide blend noted above on ten (10) volunteers (7 male, 3 Female, Ages 25- 60) to examine skin barrier recovery after a tape stripping disruption.10
The volunteers,
who all signed informed consent, were recruited to examine the impact of application of a formulation containing the water-soluble polysaccharide blend at 3%. Each volunteer was tape stripped at two locations on the inner volar forearm to disrupt the skin’s barrier and a third location served as an undisrupted control site. Tape stripping was done so that each site had an initial TEWL measurement that was at least 2X the TEWL value of a non-tape-stripped control site. In most cases, approximately 15-20 tape strips (3M Duct Tape) produced the desired TEWL values required to initiate treatments. Product application commenced 1 hour after the tape stripping and initial measurements and photographs and continued for 60 hours with treatments 2X/day with two formulations: 1) a placebo

cream and 2) the same cream containing 3% of the polysaccharide blend. Trans- Epidermal Water Loss (TEWL) was measured using a DermaLab TEWL-meter [Cortex Technology, Hadsund, Denmark]. Measurements were made under controlled air-conditioned conditions at 23°C and approximately 30 RH. The entire protocol can be seen in Figure 8. To examine the impact of the
treatments, the difference in the overall average TEWL measurements at T0 (initial measurement) and T5 (final measurement) were examined, Fig 9. Examining the change gives an indication as to how effectively the active treatment compared against the placebo treatment. As can be seen, the overall rate of barrier recovery for the active-treated site was significantly higher than the placebo-treated site by approximately 6% (Paired T-Test, p≤0.05) and both sites improved significantly compared to the untreated site. In addition, the Erythemal Index of the skin was examined using a DermaLab Chromometer [Cortex Technologies, Hadsund, Denmark]. The change in redness from T0 to T5 indicates that the active-treated site improves
more quickly than the placebo site by 36%, indicating the active treatment appears to be also helping to reduce skin redness over the treatment time frame (Fig 10). Photographs of each individual show
differences between the control site and the active and placebo sites and a representative example of one test subject’s inner volar forearm taken in natural sunlight to enhance the barrier disruption appearance at T0 and T5 is shown in Figure 11. The instrumental and photographic data indicate that the treatment containing the 3% polysaccharide blend functioned superiorly to the placebo treatment at accelerating the repair of the skin’s disrupted barrier. Additional studies are being planned to examine inflammation resulting from UV exposure to examine the benefits of the antioxidant blends.
Clinical examination of the polysaccharide blend on extended skin hydration There is a well-established link between wound healing and the moisture content of the skin. The most common example of this is how much more quickly wounds inside of the mouth heal compared to wounds outside
