What red light therapy can do for you

LightStim delivers light energy to your skin much the way plants take in light from the sun. Each LightStim device uses different wavelengths, or colors, of light. The LightStim ProPanel provides rejuvenating wavelengths for signs of aging and for acne.

Signs of aging

Rejuvenating wavelengths for skin that looks smoother and more rested.

Acne

Wavelengths chosen to help calm breakouts.

A warm, soothing treatment you can simply relax into.

Red light therapy and skin longevity

Red light therapy is one of the tools I use when we plan for the long run. It sits alongside sunscreen, a retinoid and in-office treatments in a longevity dermatology plan, matched to your skin and your stage of life.

Is red light therapy right for you?

If you want a gentle, regular treatment that fits easily into your week, red light therapy may suit you. We plan it for every skin tone and type, starting with your history and your goals.

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 takes 10 to 20 minutes under the LightStim ProPanel. You relax, listen to music or meditate while the warm light does its work. Afterward we stay in touch and follow your calendar together, helping you reach your goals and making every decade your most beautiful best.

A rhythm that builds

I recommend a series of 3 to 5 sessions, spaced one week apart, then maintenance every 6 weeks to keep your skin on track.

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.

Eligibility

You MAY qualify if you can answer YES to all:

I am a healthy female (peri or menopausal) between the ages of 40 and 65.

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.
