What Fotona 4D and 5D can do for you

Fotona combines two kinds of laser light on the Fotona Dynamis platform. Er:YAG light is absorbed strongly by water, so it acts close to the surface. Nd:YAG light reaches deeper. Together they let one treatment refresh the surface, warm deeper layers and calm redness, for collagen renewal across the layers of your skin.

Tighter

Firms laxity and helps define the jawline and brow.

Smoother

Softens lines and wrinkles, including fine lines around the eyes and mouth.

Calmer

Helps with redness for a more even look.

Fotona 4D or 5D?

Fotona 5D adds a skin tightening step that focuses on specific areas of the face and neck. We choose between the two at your consultation, based on your goals.

Fotona vs CO2

Choose by the size of change you want and the recovery time you have. Fotona 4D works gradually across a series with minimal downtime. UltraPulse CO2 is ablative resurfacing, and healing takes about 7 to 10 days. The laser treatments in NYC page explains every option.

Fotona vs Sofwave

Fotona is a laser series for redness, lines and laxity. Sofwave uses ultrasound for lines and lift in a single session or two. Some plans use both.

Is Fotona right for you?

If you'd like tighter, smoother skin, a lifted brow or a sharper jawline, with little time away from your day, Fotona 4D or 5D may suit you. Settings are adjusted to your skin, whatever your skin tone, starting with your history.

What to expect

  1. I

    We look together

    We look at your face together, and you tell me your goals and the features you love. Mostly, I listen.

  2. II

    Your plan for the year

    I do a full assessment, studying your face at rest and while you talk. Then I walk you through your complete plan, from skin care and your at-home routine to in-office treatments, and map it into a calendar for the year so you can plan ahead and look forward to every visit. My assistant takes notes, reviews the plan with you and gives you a printed copy, plus one by email, before you leave.

  3. III

    Treatment, then follow-up

    Each session moves through the protocol steps, with every step adjusted to your skin. Downtime is minimal, so most people return to their plans soon after. Afterward we stay in touch and follow your calendar together, helping you reach your goals and making every decade your most beautiful best.

Results that build

Fotona works gradually across a series, usually 4 to 6 sessions spaced 3 to 6 weeks apart, so your skin renews step by step.

Clinical Trials

Estrogen Study

This study is being done to see whether applying a cream with estradiol (a form of estrogen) to the face can improve overall skin quality and help reduce fine lines and wrinkles in peri- and post-menopausal women, and how this relates to epigenetic changes in the skin. A part of the study will also include applying an extra rapamycin analog cream to the face, which is also believed to improve overall skin quality and help reduce fine lines and wrinkles.

WHY THIS MATTERS

Skin aging in peri- and post-menopausal women is deeply tied to hormonal shifts. This study explores whether topical estradiol can help reset aging skin, cellularly.

I have not had any cosmetic facial treatments in the last 1-3 months.

I have not had any GLP-1 treatments in the last 6 months.

Study Design and Duration

The study includes daily evening application of study cream for 12 weeks, followed by 4 weeks with no test product use. In total, the study will last 16 weeks or approximately 4 months.
