Skin treatments run on Alma platforms: Harmony (ClearLift, ClearSkin, IPL Photofacial and Dye VL), CO2 Hybrid resurfacing and Opus Plasma. Microneedling, The Perfect Derma Peel and the Alma iQ Skin Assessment sit on the same menu.
Body treatments include laser hair removal, laser tattoo removal and spider vein removal.
Wellness services include medical weight loss with GLP-1 and dual GIP/GLP-1 medication, peptide therapy and vitamin injections such as B12 and MIC.
Not sure which menu fits? The concerns pages start from the problem instead, such as volume loss or hyperpigmentation.
Medical-grade skincare contains higher concentrations of active ingredients than over-the-counter products, and it is sold only through licensed professionals. The office carries two lines: Avelli Advanced Skin and Revision Skincare®, including Intellishade® and C+ Correcting Complex 30%. Products can be matched to your skin with an Alma iQ Skin Assessment, which images your skin to measure hydration, texture and pigmentation while you watch.

Booking is by phone at 516-442-7088 or through the contact form; there is no online booking calendar. Your first appointment opens with a consultation, where your goals, medical history and the area you want to treat are reviewed before a plan is agreed. For fillers, the price is quoted at that consultation, before any treatment starts. If you would rather spread the cost, Cherry patient financing checks your options with a soft credit check that does not affect your credit score.
Call 516-442-7088 or request an appointment online. The office is open Monday to Saturday, 9am to 5pm, and you can ask about financing when you call.
