Meet Dr. Allyson Brennan, Founder & Clinical Pharmacist
Meet The Founder
Dr. Allyson Brennan
A neuroscience clinical pharmacist who spent two decades in hospital practice- and now is a cosmetic chemist who formulates skincare with the same standard she brought to critical patient care.
Chemistry, with heart
Allyson Gregory Brennan, PharmD., is the founder and formulator of Emogene & Co. She built the brand on a simple conviction: skincare should be judged by what’s actually in a skincare formula and whether the science holds up, not by the packaging or the marketing budget.
Every formula she makes carries a purpose behind each chosen ingredient, the same way she once accounted for every medication at a patient’s bedside.
The Origin
It started with a bottle of vitamin C serum on the bathroom counter
Allyson was a new mother and a working pharmacist when she bought an expensive vitamin C serum — the kind with beautiful packaging and a clinical-sounding name. The next night she flipped the bottle over and read the label. Her pharmacist instincts kicked in immediately. The vitamin C wasn't a form she recognized, and the formula had already oxidized—clear signs that the product had lost much of its effectiveness before it ever made it into a customer's hands.
This observation ignited her curiosity and a deeper look into the skincare industry. She kept finding the same pattern: money spent on marketing instead of education, ingredients that work better together split across separate products to sell more bottles, and shoppers left with no way to know the difference. So she did what a chemistry mind does — she made her own, calculating the concentration and incorporating supportive ingredients into the formula that would actually be effective and safe for skin.
She kept the formula to herself, using it daily. Within weeks, friends began asking why her skin looked so good and begged to try her homemade creation.
After nearly ten months of refining every ingredient and every detail, their encouragement gave her the confidence to create a company to share her creation beyond her own bathroom counter.
The company name came easily. Her grandmother was Emogene — a Southern woman who could make a five-course meal from almost nothing and created beauty from whatever she had in front of her.
Allyson and her daughter, Parker, share the same middle name: Emogene. Three generations of women, one name. Emogene & Co. was her way of honoring all of it.
What began in her dining room lined with shelving holding ingredients, glass measuring beakers and syringes — hand-filled bottles at three in the morning, deliveries on the way to her shift as the hospital each day — is now a small-batch operation run out of a 5,000-square-foot facility on a private wooded property in Tennessee, three miles from the farm where she and Parker live.
Background
The credentials behind the formulas
Clinical Pharmacist
Two decades of hospital practice, with a focus in neurocritical care and neurosciences- reading clinical studies and understanding how compounds move through tissue was the daily work.
Doctor of Pharmacy
PharmD. from the University of Mississippi, with an undergraduate degree in pharmaceutical sciences, and additional undergraduate degrees in biology, chemistry, and psychology from Millsaps College.
Founder & Formulator
Founder of Emogene & Co., where she personally develops the small-batch, skin health focused formulas and still runs all customer care herself.
“We’re here for your skin’s health. The sale is a side effect of that — not the other way around.”
A brand built like a practice
Allyson set out to build Emogene the way she practiced pharmacy: every order includes a personalized regimen card, every formula has a specific purpose behind each ingredient, and the Emogene & Co. team will point you to a non-Emogene product if that’s what your skin actually needs.
The guiding idea is to treat skin as what it is — the body’s largest organ — and to care for its health rather than chase trends. Beautiful skin is the result of this focus.
Three generations of women, creating something honest and full of heart — and Allyson is just getting started.
