Conditions Treated


Signs of Aging

When you age, your skin follows. Common age-related concerns include crow's feet, wrinkles, frown lines, or skin discoloration. Many of these concerns can be treated with our non-surgical procedures.

Unwanted Hair

Unwanted hair on your face or body can make life difficult. Unfortunately, traditional forms of hair removal such as shaving, waxing, and sugaring can require time-consuming, painful upkeep. Laser hair removal can dramatically reduce hair growth anywhere on your body, including your back, legs, bikini line, rear end, and face.

Skin Conditions

Spa procedures can also address medical conditions like rosacea, acne, and acne scarring. Our plastic surgeon will thoroughly evaluate your condition to ensure that treatment is the right fit.

Varicose Veins

Varicose veins can make your face and legs look blotchy and uneven, leaving you feeling too uncomfortable to wear certain clothes.

Laser Treatments

Full Face Laser Skin Resurfacing

Skin resurfacing can dramatically improve the health and appearance of your skin in just one session followed by a few days of downtime.

Varicose Vein Treatments

Darien, CT, visitors can also address spider veins on their thighs and lower legs with this technology.

IPL™ Photofacial

An intense pulse light (IPL) photofacial uses a special light to reduce blemishes and rejuvenate the overall appearance of your dermal tissue.

Forever Young BBL™ Fotofacial by Sciton®

BBL, or BroadBand Light, is one of the most powerful technologies available to address signs of aging, sun damage, and other blemishes. The BBL Forever Young Fotofacial has quickly become one of the most popular treatments at our practice because it is clinically proven to keep skin looking young for longer than IPL and other similar treatments.

Laser Hair Removal

Laser hair removal is a popular alternative to traditional methods of hair removal like shaving and waxing. Our team uses the Forever Bare BBL™ by Sciton to safely and effectively conduct laser hair removal. With regular sessions, laser hair removal can significantly reduce hair growth.

Deep Laser Resurfacing

Our practice is equipped with the gold standard in laser technology—the Sciton JOULE erbium laser. Dr. Passaretti can use this laser to dramatically reduce the appearance of wrinkles all the way up to the lash line. The procedure is only performed under the care of Dr. Passaretti. To keep the treatment comfortable and pain-free, patients who undergo this treatment will receive light sedation. Although deep laser resurfacing has a longer downtime compared to other treatments, the results are impressive and long-lasting.

Acne Scarring Treatment

Our spa team can use this technology to remove damaged scar tissue and improve the appearance of scarred dermal tissue.

Weekend Treatments

Our team uses the NanoLaserPeel™ by Sciton to perform weekend laser treatments. With fractional laser treatments, our team can achieve deeper resurfacing with a short three-day healing period. The treatment can also be combined with the Forever Young BBL Fotofacial for a multimodality treatment.

Skin Tightening

By heating the collagen under the skin, laser skin tightening can reduce elasticity and give you firmer facial features. Our team uses the SkinTyte™device by Sciton to safely, quickly, and effectively perform treatment on all skin types.

Injectables & Fillers

Injectables and dermal fillers are cost-effective skin rejuvenation treatments that take just minutes to apply. BOTOX® Cosmetic reduces the appearance of crow's feet, while fillers like Radiesse™and JUVÉDERM® fill moderate to deep lines that develop around the nose and mouth. Our injectables and fillers include:

Using the Latest Techniques


Needles are an outdated method of administering dermal fillers. For some patients, they lead to unnecessary negative side effects like bruising and pain.

When injecting dermal fillers into the lips, cheeks, and under the eyes, Dr. Passaretti uses a new microcannula technique. A microcannula is a tiny blunt tube that offers several advantages compared to traditional, outdated techniques:

  • Smoother application
  • More natural-looking results
  • Virtually no bruising or pain

Because the microcannula technique requires a more experienced injector, patients visit Dr. Passaretti from all over the state to enjoy the benefits of this modern tool.

"All True Professionals"

"Starting with my initial consultation all the way through my 3 month post op visit, I was always welcomed with a smile and felt comfortable to any ask questions that I had. Dr. Passaretti and his staff are all true professionals and deeply care about their patients and take pride in their work."

- Danielle S.

Skincare Treatments

We provide a wide range of spa treatments from glycolic peels, which soften fine lines and wrinkles, to chemical peels, which tighten and renew the facial tissues. We also provide microdermabrasion to gently remove dead tissue and reduce the look of pores and scarring. Our skincare treatments include:


Our practice is equipped with its own hydrafacial machine. This machine floods the skin with glycolic acid, antioxidants, and other substances that deep clean the surface, giving men and women the "runway glow" they desire.

Microdermabrasion is a minimally invasive treatment that works by gently exfoliating the upper layers of tissue, removing dead cells and improving the tone, texture, and appearance of your skin.

Our team uses the SkinPen® microneedling device by Bellus Medical. SkinPen is the first microneedling device approved by the U.S. Food and Drug Administration (FDA). While older microneedling devices are reused from patient to patient, increasing the risk of contamination and skin damage, the SkinPen is a single-use device. By creating thousands of tiny injuries on the surface of the skin, SkinPen encourages collagen production and new skin growth. Microneedling is safe for all skin types and is currently the preferred treatment for acne scars and injury scars throughout the face and body.

RF Microneedling

Microneedling is a procedure that resurfaces your skin. It is a minimally invasive treatment that stimulates your lower layers of skin to produce additional foundational healing substances such as collagen and elastin, resulting in more youthful-looking, tighter skin.

At The Aesthetic Center, we want to keep treatments as safe and comfortable as possible. In addition to offering light sedation for our more invasive treatments, we use a cryo chiller to deliver cool air to the treatment area during the procedure.
