Can I use the balsam if my heels are cracked?

No — the manufacturer's guidance is clear that the balsam should be used only on intact skin, and cracked, broken or infected areas should be avoided. There are practical reasons for this: open cracks expose deeper, more sensitive skin layers, and applying an active cosmetic formula there can cause stinging or irritation and may introduce bacteria into a compromised area.

A sensible sequence if your heels are currently cracked:

• Deep or painful cracks first. Fissures that bleed, hurt when you walk or show signs of infection (redness, warmth, discharge) are a matter for a doctor or podiatrist, not a cosmetic product.
• Shallow surface cracks often close up with gentler basic care — protecting the area, avoiding aggressive filing, and keeping the skin covered and moisturised with a plain, bland emollient.
• Once the skin surface is intact again, this balsam fits well as ongoing maintenance: the softening action of purified bile extract on thick, calloused skin addresses exactly the kind of rigid, dry buildup that tends to crack under pressure in the first place. Regular application after a warm foot soak, with a few minutes of massage, helps keep the heel skin more flexible.

If cracking keeps returning despite consistent care, mention it to a specialist, as recurring fissures can have underlying causes that skin care alone will not address.
