J. Nyirady et al., A comparative evaluation of tretinoin gel microsphere, 0.1%, versus tretinoin cream, 0,025%, in reducing facial shine, CUTIS, 66(2), 2000, pp. 153-156
Tretinoin gel microsphere, 0.1%, is a highly effective anti-acne medication
formulated with sponge-like microspheres encapsulating the active ingredie
nt, tretinoin. In addition to minimizing cutaneous irritation, this system
may also reduce facial shine. This single-center, double-blind, half-face s
tudy evaluated the potential of tretinoin gel microsphere, 0.1%, to reduce
the appearance of facial shine compared to tretinoin cream, 0.025%. Thirty-
five subjects (ages 12 to 24 years) with moderate acne vulgaris and moderat
e facial oiliness, were evaluated after 4 consecutive days of product use.
On sides treated with tretinoin gel microsphere, 0.1%, investigators found
significantly reduced facial shine at 3 and 6 hours posttreatment. Subjects
' self-evaluations revealed a significant reduction in facial shine at 3 ho
urs posttreatment. Photographic analyses showed reductions in facial shine
for both treatments, but decreases were greater on tretinoin gel microspher
e, 0.1%-treated sides. Both therapies were well tolerated, and no adverse e
vents occurred. Tretinoin gel microsphere, 0.1%, has the added benefit of r
educing the appearance of facial shine, which is a frequent concern in acne
patients.
