Owner - Sarah Koshko


Hi there, my name is Sarah Koshko and I am the owner of Skin Haus Co. I am a medical aesthetician and a certified laser technician specializing in customized facials, microneedling, dermaplaning, chemical peels, and light therapy for all skin types, with a focus on age management, teenage and adult-onset acne, and sensitized skin.

My initial skin analysis includes a basic lifestyle assessment to help identify and eliminate what factors may be contributing to your skincare concerns and problems. I also reassess your skin on a regular basis, since your internal chemistry and environment is always changing.  


Some of the questions I might ask are:

  • What foods are you eating? 

  • What supplements and/or medications are you taking?

  • What is your skin care regimen (or lack thereof) and what make-up are you using? 

  • What products and procedures have you used in the past that have or have not been successful?

  • Are you currently working with a dermatologist?

Based on this information, I will recommend what products and procedures you will most benefit from. I will tell you what you can realistically expect from your treatments and products, including any downtime that may be anticipated. I can also help you modify and prioritize your plan, based on time, work schedule and/or budget.


Whether it is your first time seeking a skin care consultation or you have been advised by multiple estheticians / dermatologists in the past with no success, my goal is to save you time, energy, and money by providing the quickest, most effective treatments to achieve optimum results. I will help you achieve this by providing customized clinical skin care treatments/products, unlike common “frou-frou” spa services. I am always focusing on continuing education and am constantly updating my treatment protocols, due to new products and technology in this ever-changing industry. 


I pride myself on attention to detail and am devoted to exceptional customer service. I always make my clients feel comfortable and relaxed while maintaining a progressive approach on anti-aging.


I will guide you step-by-step with your best interest in mind!  I truly have a passion for helping others and want to make you look and feel like the best version of yourself!
