The health tech platform for skin

The AI-powered beauty mirror that acts as your personal aesthetician, bringing Korean med-spa skin imaging and analysis into your home.

Measurable, objective, data-driven skincare

The problem

Consumers track everything, except their skin

We all measure sleep, workouts and biomarkers routinely.

$194B+ Global skincare market

Today's market thrives on:

  • Consumer psychology
  • Influencer-driven endorsements
  • Viral trends
  • Discovery of new ingredients (PDRN, peptides, niacinamide)
  • Luxury experience and packaging

Consumers will pay high prices for skincare products, devices and treatments. But a confusing, hype-driven market makes it hard to know what actually works.

Low ability to track or verify results.

Precision imaging

Why hardware matters

For AI to deliver reliable insights and truly personalize skincare, the quality of the input data is paramount.

Smartphone apps

No lighting hardware

Variable lighting

Ambient light drastically alters how skin appears.

Inconsistent angles

Different selfie angles skew texture and topography.

Poor repeatability

No two smartphone photos are truly comparable.

Garbage in, garbage out: unreliable data prevents accurate analysis and effective recommendations.

Ester hardware

Clinical-grade input

Controlled optics

Uniform, multispectral illumination: white light, cross-polarized light and UVA light.

Precise capture

Fixed distance and computer vision ensure consistent, high-resolution imagery.

Scientific repeatability

Every scan is comparable, enabling true longitudinal tracking.

A dedicated device captures clinical-grade imaging, as fundamental to AI-driven skincare as high-quality imaging is to AI radiology.

Meet Ester

Health tracking, now available for skincare

  • Access clinical-grade insights at home in a luxury, everyday mirror
  • Track the metrics that matter to improve your skincare regimen
  • Take skincare from guesswork to evidence-based outcomes

Close your eyes and complete a full skin scan in 1 second.

Ester takes skincare from a beauty ritual to quantified health.

Technology

Multispectral 3D imaging reveals the invisible

Advanced imaging and calibrated sensors quantify markers of aging and health that lie beneath the epidermis, invisible to any standard mirror.

Predict

Highlights subclinical acne porphyrins to fight breakouts before they occur.

Prevent

Reveals invisible UV damage before sun spots and permanent wrinkles surface.

Track

UV damage, acne porphyrins, brown spots and wrinkles, pores, texture, redness and hydration.

Correct

Tracks pigmentation changes to optimize skin tone interventions.

Ester's value

Proven clinical-grade measurement, brought home

The technology exists today, but only in a clinical setting. Ester bridges the gap between episodic care and daily skin health.

In the clinic today

At home with Ester

From a medical device: VISIA-CR

The gold standard for professional skin analysis: detailed, high-resolution imaging in a clinical environment.

To a consumer product: the Ester mirror

Clinical-grade imaging in the home, so people can track and understand their skin health with ease.

From a medical encounter: the dermatologist

90% of dermatologist time is spent on aesthetics.

To an app: Ester, everyone's aesthetician

Personalized insights, product recommendations and outcomes tracking.

The Ester app, Ask Ester screen

The last untracked organ: your skin

Objective

Measures what is. Clinical imaging, biomarker testing, diagnostic devices. The science exists. Consumer access doesn't.

Ester's target space

Skintelligence

Clinical-grade skin intelligence that compounds over time. Every scan becomes part of a living record. The longer you use it, the more valuable it becomes: the difference between knowing your skin today and understanding it over time.

Single moments. The VISIA scan. The derm appointment. The med spa consultation. Snapshots that capture a day but remember nothing about the year.

Episodic

Longitudinal

Measures what we hope is true. Claims. Testimonials. 'Clinically proven.' The guessing era, packaged beautifully.

Subjective

How it works

Ester translates complex 3D face scans into one intuitive number, your Ester Skin Age. It establishes a quantifiable baseline and turns subjective feelings into evidence-based outcomes.

Future revenue

B2B products

As the data compounds, Ester adds data revenue streams.

01

Brand insights

Skincare brands

See how products perform across user cohorts with market performance data.

02

Clinical R&D

Trial sponsors

Run clinical trials on opt-in users to validate products at a fraction of traditional cost and scale.

03

Telehealth

Dermatologists

Standardized imaging and a historical skin record between visits, resulting in stronger adherence, clinic efficiency and improved retention.

Why we win

A scan is a moment. Skintelligence is a relationship.

Competitors can copy your product. They can’t copy years of a customer’s skin data.

  • Every scan is comparable: same optics, distance, light
  • Products and routines linked for measurable outcomes (proprietary efficacy map)
  • Models improve with every scan

After 10,000 scans

Ester will be the only platform that can tell you whether the product you’re using actually reduces skin age for your specific age, ethnicity, lifestyle and climate.

Ester will close the 90+ day gap between derm visits, when no one can see what your skin is doing.

No skincare brand, dermatologist or review site can do this.

Progress

What we’ve already de-risked

01

Design

Partnered with Ammunition, the design firm behind Beats by Dre, Adobe and Lyft’s brand. Industrial design is underway, moving from concept to engineering prototype.

02

Tech

The core imaging science is already proven in clinical settings (VISIA-CR is the dermatology gold standard). Our technical work is miniaturizing it into a consumer device. A functional prototype is developed and moving toward component lock.

03

Brand

Brand identity in development with Outset LA, positioning Ester as a $500 premium wellness object.

04

Clinical validation

Dr. Rishi Chopra (Harvard-trained, top-of-field aesthetic dermatologist) and Dr. Eleni Linos (dermatologist and Director of the Stanford Center for Digital Health) are advising on clinical validation.
