The Science of Sweat And Skin Balance With Surface Deep
In this episode of Skin Anarchy, Dr. Ekta sits down with board-certified dermatologist and Surface Deep founder, Dr. Alicia Zalka, to challenge everything you thought you knew about deodorant and body care. With over three decades in medical dermatology, Dr. Zalka shares why the underarm — and the rest of your body — deserves the same ingredient-conscious, science-backed attention we give our faces. Her journey from clinic to product creation started with an accidental discovery: a forgotten deodorant, a swipe of glycolic acid, and a surprising odor-free day.
Unlike conventional deodorants that mask odor or antiperspirants that block sweat, Surface Deep takes a different route — keeping skin’s pH balanced, supporting beneficial bacteria, and creating an environment where odor-causing microbes can’t thrive. Dr. Zalka explains the science behind sweat, the role of the skin microbiome, and why killing all bacteria is not the goal.
She also dives into the delicate nature of underarm skin, why common deodorant ingredients can cause irritation, and how glycolic acid — when formulated correctly — can be a game changer for smooth, odor-free skin. Beyond the underarms, Dr. Zalka introduces the “Stinky Seven” — seven surprising body zones prone to odor — and her take on the rise of whole-body deodorants.
This conversation is equal parts myth-busting and practical skin science. If you’ve ever wondered why your deodorant stops working, what’s really behind body odor, or how to care for your skin without disrupting its natural balance, this episode will change the way you think about body care forever.
