This is a self-controlled single-site study of healthy subjects receiving an ablative fractional CO2 (carbon dioxide) laser procedure followed by topical application of NanoDOX® Hydrogel (1% doxycycline). The study includes skin biopsies to evaluate the effects of NanoDOX® Doxycycline Monohydrate Gel on wound healing after the ablative laser procedure. Study subjects will be asked to do 2 visits of 4 hours in total over approximately 1 week. An optional third visit will take place approximately 6 weeks after Visit 1. In this study, 20 subjects are expected to enroll with a goal of 12 healthy subjects to enroll and complete the study.
Effective topical delivery of any pharmaceutical agent requires small molecule drugs to penetrate the epidermis, yet the absorption of topical products through the epidermis is limited. In this study, the investigators are looking for healthy volunteers who are eligible to help us to determine the safety and efficacy of ablative fractional laser therapy combined with NanoDOX. The investigators are doing the research to evaluate drug delivery of topical NanoDOX® Hydrogel following ablative fractional CO2 laser treatment and our secondary objective is to evaluate the efficacy of NanoDOX® for wound healing. Subjects will have a screening visit to determine eligibility, 2 study visits when they will receive CO2 ablative fractional laser treatment, NanoDOX® Hydrogel application, and skin biopsies, and 1 optional study visit for wound healing assessment. Laser procedure will happen only during visit 1, visit 2 will happen 2 days after visit 1, and visit 3 will happen approximately 6 weeks after visit 1. In total, 7 skin biopsies will be performed.

NanoDOX® Hydrogel (Doxycycline Monohydrate USP) will be applied on the areas of the skin previously treated by the Co2 Ablative Fractional Laser and also on a small non treated area of the subject's skin
CO2 Ablative Fractional Laser will be applied to healthy skin areas

Skin drug uptake
The depth of drug uptake will be measured by histology analysis. To determine if ablative fractional laser therapy combined with NanoDOX® topical drug improves the depth of drug uptake, fluorescence microscopy will be used to measure the concentration of the drug inside the skin by the amount of fluorescence created by the drug will be quantified.
Time frame: 3 days
Wound healing
Biopsied areas will not be sutured, so wound healing will be evaluated by clinical assessment; the investigators will assess the wounds on the untreated and treated areas with NanoDOX® Hydrogel after ablative fractional laser.
Time frame: 6 weeks
