About Us

Eczema, acne, psoriasis, and other skin diseases can be debilitating and affect every aspect of our lives. From attendance at school and work to our relationships, self-esteem, sleep, and everyday well-being. If we feel uncomfortable in our skin, we feel uncomfortable in our lives. But too often, our concerns are dismissed as "just a rash" or "just pimples". Too often, a fundamental issue in our bodies is patched over with a steroid cream without addressing its root causes.

But it's not just a rash. Our skin is a window into our overall health. When our skin barrier is broken, bacteria and other germs can easily enter our bodies. And the reverse is also true - when our health is off, it shows up on our skin. Our gut, immune system, mental health, hormones, and the environment we live in all affect our skin.

There are great treatments available to treat our skin health holistically. Unfortunately, patients often lack a guide who helps them connect the dots, from their dermatologist to a dietitian or from their ObGyn to the dermatologist. Better treatment is possible.

That's why we founded Lemma Health.

At Lemma Health, every patient has access to affordable evidence-based treatments - today, not in three months. Every patient has the right to be the main decision-maker about their own health, guided by doctors and easy-to-understand information. For every patient, there is an ideal treatment plan - and at Lemma Health, we're determined to find yours. At Lemma Health, we believe that we can treat diseases better if we don't just patch up the symptoms, but address the root causes holistically.

Why Lemma? We chose the name "Lemma" for our company because it reflects how we see our role in your healing journey. In mathematics, a lemma is an intermediate step—a building block that helps you reach the final proof. As math nerds, we loved the idea that Lemma Health could be that essential step in your journey to manage your eczema. We’re here to provide you with information, tools, and support, but the biggest step to lasting relief can only be taken by you.

If you are looking for a solution for your skin health, you've come to the right place. We look forward to working with you!
