In this episode with Lucy Goff, you'll hear how a near-fatal bout of septicemia after childbirth sent her on a decade-long search through the world's leading science institutions, and how that search led to LYMA, a company built around the conviction that damaging your skin to improve it is the wrong approach entirely. You'll discover why the collagen you get from ablative lasers, microneedling, and radiofrequency is scar collagen, how cold laser works by a completely different mechanism, and what a head-to-head gene expression study in human skin revealed when a cold laser was compared to an LED running ten times the power.
Lucy Goff is a former journalist and luxury publicist who walked away from a successful career to change the wellness industry from the ground up. She launched the LYMA Supplement in 2018, followed by the LYMA Laser, the first FDA-cleared at-home clinical-grade laser. LYMA is now recognized as one of Fast Company's Most Innovative Beauty Companies, a King's Award for Enterprise winner, and one of the fastest-growing private companies in Britain.

Mindsip insights from this episode:
Regenerate skin and muscle with LYMA laser
The LYMA laser regenerates not only the skin but also the underlying muscle, which is crucial because sagging muscle is a primary cause of sagging skin.
Utilize laser light's unique properties for deeper skin penetration
For light to penetrate beneath the skin's surface, it must be coherent, polarized, and monochromatic—three properties exclusive to laser light, not LED.
Utilize knee cartilage technology to rejuvenate skin
The technology for the LYMA laser was inspired by a medical device used to rebuild knee cartilage, after it was observed to make the skin on the treated knee look 20 years younger.
Activate epigenetic switch with cold laser technology
This cold laser technology triggers an epigenetic switch inside your cells, making them operate as they did when you were younger without causing any damage.
Activate SIRT1 longevity gene with LYMA laser
In a clinical study, the LYMA laser expressed 45 genes in the skin's dermis, including accelerating the SIRT1 longevity gene by six times, while an identical LED device expressed only one.
Recognize internal damage from heat-based treatments in plastic surgery
Plastic surgeons can identify patients who have used heat-based damaging treatments because they can see the scarred muscle and dermis tissue during procedures like facelifts.
Avoid damaging beauty treatments that mimic scar tissue
Beauty treatments that damage the skin to stimulate collagen, such as microneedling or radiofrequency, create a disordered blend of collagen fibers similar to scar tissue.
Achieve optimal therapeutic laser dose of 12 joules in three minutes
The optimal therapeutic dose of laser light to trigger an epigenetic switch in your skin is 12 joules, which is achieved by holding the device in one spot for three minutes.
