Treatment of Facial Photodamage With Mass Market Topical Products vs Non-ablative Fractional Laser.

Methods: In this split-face, evaluator-blinded study, 18 subjects were randomly assigned to receive either the SSR or NFL treatments on each side of the face. For the SSR facial sides subjects followed two morning-evening regimens. On the NFL sides subjects were treated 3 times with the 1927-nm laser at 4-week intervals.

Comparative Study of Professional vs Mass Market Topical Products for Treatment of Facial Photodamage.

Background: Many over the counter topical products claim to reverse the signs of cutaneous photo-damage. To date, the two most studied ingredients for improving the texture, tone, and pigmentation of the skin are topical retinoids and hydroquinone.

Objective: This split face study compares a mass market skincare regimen with a prescription skin care regimen for improvement in photo damaged skin.

Evaluation of a novel home skin care platform.

The home beauty device market is rapidly growing, having more than tripled in the last four years. This study evaluates several specific attachment heads using a novel home skincare platform (HSP). By incorporating multiple treatment heads for cleansing, skin smoothing, and skin infusion, this device has the potential to address many potential treatment goals.

Speciation within Columnea section Angustiflora (Gesneriaceae): islands, pollinators and climate.

Despite many advances in evolutionary biology, understanding the proximate mechanisms that lead to speciation for many taxonomic groups remains elusive. Phylogenetic analyses provide a means to generate well-supported estimates of species relationships. Understanding how genetic isolation (restricted gene flow) occurred in the past requires not only a well-supported molecular phylogenetic analysis, but also an understanding of when character states that define species may have changed.
