Know Your Skin Before We Treat It

Complimentary AI Skin Analysis at Every New Patient Consultation — Plainview, NY

Every new patient consultation at Stay Ageless Clinic in Plainview, NY begins with a complimentary AI-powered skin analysis — before any treatment is discussed or recommended. Using the AISIA clinical skin imaging system, Farina Sial, PA, MBA captures a detailed multi-spectral assessment of your skin across 19 clinical indicators — from surface hydration and sebum levels to deep UV pigmentation, pore diameter, sensitivity mapping, and sub-surface melanin distribution invisible to the naked eye.

This is not a questionnaire or a visual inspection. It is a 36-megapixel clinical imaging analysis using 8 spectral light modes — RGB white light, UV light, parallel and cross polarized light, blue light (for bacteria and acne prediction), Wu's spectrum (deep pigment), and thermal heat mapping — that reveals what is happening in your skin from surface to dermis. The results are compiled into a printed diagnostic report you take home. This is how Stay Ageless Clinic makes recommendations: from clinical data, not guesswork.
