Cryoderm is, indeed, very powerful, that is because it contains not only 3 times more of the active ingrediant (menthol 10% vs 3.5% in BF), but also it has other beneficial and century-proven herbal ingredients that reduce inflammation, bruising, swelling and speeds up the body's natural healing, beside blocking the pain!!!
Also, BF contains some harmful ingredients, that I feel bad about using on my patients long-term, as one of them (isopropyl alcohol) can cause birth defects, kidneys, liver, skin toxicity and nerve damage. As a responsible practitioner I feel obligated to provide the best care and products that are safe long-term.
