The Long Island aesthetic market has no shortage of options. There are clinics offering Botox and fillers on every block. What is far rarer — and what Stay Ageless Clinic was specifically built to provide — is a provider whose aesthetic training sits on top of a genuine medical foundation. Farina Sial, PA, MBA spent 25 years practicing hospital-based medicine at Mount Sinai South Nassau before opening this clinic. She has worked in neurosurgery. In critical care. In internal medicine. That clinical background does not just inform how she injects — it informs every decision made in the treatment room.
The result is a clinic that looks and feels different from a traditional med spa — because it is different. Every patient is assessed before any treatment is selected. Every protocol is customized. And every recommendation is made with the patient’s long-term outcome in mind, not a sales target. This is what medically guided aesthetic care looks and feels like. This is the Stay Ageless standard.
View FAQsChoosing the right provider matters. Stay Ageless Clinic is led by a licensed Physician Assistant with clinical training that supports safer, more customized care.
Farina Sial, PA, MBA practiced hospital-based medicine at Mount Sinai South Nassau for 25 years — spanning neurosurgery, critical care, and internal medicine. This is not a background detail. It is the foundation of every treatment decision she makes in the aesthetic room. You cannot replicate 25 years of hospital anatomy experience with a weekend certification. Patients who come to Stay Ageless Clinic receive the benefit of a provider who has spent decades understanding how the human body actually works — before applying that knowledge to how it looks.
Every injectable treatment at Stay Ageless Clinic begins with facial mapping — a detailed anatomical assessment of the patient’s facial structure, vascular anatomy, and aesthetic goals before any product is selected or any needle is used. Farina plans each treatment around the specific patient’s anatomy. The result is consistently natural: enhancement that works with the face rather than distorting it. This anatomy-first standard is built from 25 years of hospital anatomy — not from a training course.
Stay Ageless Clinic uses the Candela GentleMax Pro — a gold-standard FDA-cleared dual-wavelength laser system (Alexandrite 755nm + Nd:YAG 1064nm). It is one of the few Long Island clinics capable of safely performing laser hair removal, melasma correction, Laser Genesis/toning, rosacea treatment, and bruise treatment across ALL Fitzpatrick skin types — including Fitzpatrick IV–VI (darker skin tones). Every setting is individually calibrated per patient — never preset. This is laser medicine. Not laser aesthetics.
Stay Ageless Clinic integrates regenerative science — PRF, EZ Gel autologous biofiller, PDRN/Rejuran, exosomes, PDGF, and K-Beauty skin boosters — as clinical foundations, not optional add-ons. These biostimulatory protocols use your own biology to stimulate skin repair and collagen production at the cellular level, extending and enhancing the results of every other treatment. This approach reflects the direction aesthetic medicine is moving globally — and it is the standard here.
Aesthetic medicine has historically underserved patients with darker skin tones. At Stay Ageless Clinic, this is not an afterthought — it is a deliberate clinical priority. Farina has extensive experience treating South Asian, Middle Eastern, African American, and Latina patients from across Long Island. The Candela GentleMax Pro’s Nd:YAG 1064nm wavelength and conservative laser protocols ensure safe, effective treatment for all Fitzpatrick types. Every setting is calibrated per patient based on Fitzpatrick typing, not guessed from appearance.
Every consultation at Stay Ageless Clinic begins with an assessment — not a sales pitch. Farina will tell you what she recommends and why. She will also tell you what she does not recommend, and why not. If a treatment is not right for you at this time, you will not receive it. This honest, patient-first approach is reflected in 300+ five-star reviews built entirely through word of mouth and results — not advertising. The best compliment a patient can give is sending someone they care about.
Before any treatment is discussed at Stay Ageless Clinic in Plainview, NY, every new patient receives a complimentary clinical AI skin analysis — using a 36-megapixel imaging system with 8 spectral light modes to measure 19 skin indicators from surface hydration and pigmentation to deep UV spots, pore diameter, sensitivity mapping, and bacteria activity invisible to the naked eye. The results are compiled into a printed diagnostic report reviewed at your consultation. This is what assessment-first care looks like in practice: clinical data, not guesswork, not a sales pitch. The right treatment for your skin — confirmed before a single needle is used or a single product is applied.
The Candela GentleMax Pro — the gold standard in professional laser platforms — calibrated per patient, per session, per skin type. Never preset.
Most aesthetic clinics that offer laser treatments use preset programs — the same settings for every patient regardless of skin type, condition, or treatment goal. This approach produces inconsistent results at best and serious complications at worst, particularly in patients with Fitzpatrick IV–VI skin tones where incorrect settings can trigger permanent hyperpigmentation or scarring.
At Stay Ageless Clinic in Plainview, NY, every laser treatment begins with a skin assessment — Fitzpatrick typing, condition evaluation, and target area mapping. Settings are then individually calibrated: fluence, pulse duration, spot size, and cooling. The Candela GentleMax Pro’s dual wavelengths (Alexandrite 755nm for lighter skin types, Nd:YAG 1064nm for darker skin tones) allow safe, effective treatment across the full Fitzpatrick I–VI spectrum — something most Long Island laser clinics cannot offer.

Stay Ageless Clinic does not treat aesthetics as a surface problem. The most lasting improvements in skin quality, firmness, and radiance come from stimulating the body’s own biological repair mechanisms — not from filling or masking. This is why regenerative protocols are integrated into treatment planning from the start, not offered as optional extras.

Three things set Stay Ageless Clinic in Plainview, NY apart. First, Farina Sial, PA, MBA brings 25 years of hospital-based clinical experience at Mount Sinai South Nassau — a depth of anatomical expertise and patient safety awareness that most aesthetic providers simply do not have. Second, the technology — the Candela GentleMax Pro dual-wavelength laser is safe for all skin types including Fitzpatrick IV–VI, which most Long Island clinics cannot offer. Third, the approach — assessment-first, anatomy-guided, zero pressure, honest recommendations. 1,200+ patients. 300+ five-star reviews. Built entirely on results and word of mouth.
Stay Ageless Clinic in Plainview, NY is a medical aesthetic clinic — not a spa. All treatments are performed or directly supervised by Farina Sial, PA, MBA, a licensed medical professional with 25 years of hospital-based practice. The clinic operates under the medical directorship of Dr. Richard Gajdowski, M.D. — a board-certified Emergency Medicine physician with 38+ years of clinical experience.

The difference is clinical training, anatomical knowledge, and accountability. Farina Sial, PA, MBA spent 25 years practicing medicine in a hospital setting before performing any aesthetic injections. She understands the vascular anatomy of the face from years of surgical and clinical practice — not from a weekend course. Complications from injectable treatments — vascular occlusion, tissue necrosis, nerve damage — are rare but serious. The provider’s anatomical training and clinical judgment are what prevent and manage them. That training is the difference between a clinical result and a medical emergency.
