Perry AntelmanCEO, Founder
Our story starts with a research chemist, Perry Antelman's father, whose work with mineral compounds revealed advanced therapeutic properties conventional topicals couldn't match. Perry saw the results firsthand and founded Aidance Scientific in 2004 to turn that science into something people could actually use.
That's where our high standards come from. From formulation to sourcing, manufacturing, and testing, every terrasil® product is created under rigorous quality protocols, safe, gentle, effective, and consistently dependable.

You With Your Skin
How fast does it work?
Many people feel relief within the first day. The active pharmaceutical ingredient, our patented Activated Minerals® and targeted botanicals go to work together from the first application; full healing depends on the condition, but most notice a real difference within a few days.
Is it safe for sensitive skin?
Yes, our formulas are made for skin that reacts to everything else. No parabens, no synthetic fragrance, and no harsh preservatives to trigger a reaction.
What is Activated Minerals?
Activated Minerals® are terrasil's proprietary technology, composed of positively-charged (2+) mineral species (i.e., magnesium oxide, zinc oxide, and silver stearate), and is backed by 20+ years of research. Our products are formulated with active pharmaceutical ingredients, Activated Minerals and beneficial botanical ingredients. Combined, our formulations go deep to the affected area bringing soothing relief and supporting your skin's natural healing.
Do you use steroids?
Never. Steroids thin the skin and only pause the problem. Our formulas use natural actives to help rebuild the skin barrier so it can defend itself.
Can I use it every day?
Yes. The formulas are gentle enough for daily use, many people keep using them to maintain healthy skin long after the initial concern clears.
