Salve Ingredients

Tea tree & lavender oil provide antiseptic and anti-inflammatory properties, reducing inflammation and preventing infection where your ​calluses are the thickest and most porous. Shea butter & beeswax form a protective barrier, locking in moisture and shielding from further ​damage. These ingredients, along with vitamin E, a potent antioxidant, promote skin cell regeneration, accelerating the healing of all your ​cracks, tears, and 'flappers.' Arrowroot extract absorbs excess moisture and soothes irritation, leaving your calluses smooth without a ​greasy residue. Moringa & calendula oil, rich in antioxidants and antimicrobial properties, protect from free radicals reinforcing your skin’s ​natural barrier.

Your skin calluses naturally.
It should be nourished the same way

Why You Shouldn't Let Your Calluses Get Too Thick

As your calluses become excessively thick, it hinders the blood flow to the underlying tissues (the ​stratum basale and spinosum) which are responsible for cell regeneration and repair. Without ​sufficient blood supply, these layers lack essential nutrients and oxygen to regenerate leading to ​tissue damage and weakened skin structure. The outer layers of your calluses become dry and less ​resistant to tearing. Calloused hands are already prone to dryness and dehydration, worsening the ​issue. Dry skin is less flexible and more likely to crack or rip under pressure, particularly in areas ​subject to repetitive stress, like your fingers and palms.

It's Not Your Actual Callus That Rips

Understanding Why Calluses Tear

When calluses tear, it's not the callus itself that's ripping apart, it's the skin around your callus and the layers of tissue beneath that suffer. Your ​calluses are primarily composed of thickened layers of dead skin cells (keratinocytes). The tissue under your calluses is composed of multiple ​layers of live cells held together by intercellular connections and structure. Your calluses do not have the same adhesive properties or intercellular ​connections, which makes them prone to detaching from the living tissue underneath when you subject them to extreme pressure or stress due to ​momentum. The thicker your calluses build, the more rigid and inflexible they become, reducing functionality, and turning your calluses into a ​liability rather than an asset.

While calluses serve as a natural defense mechanism, recognize their limitations, and give them a ‘ hand’ - no pun intended. Maintain that delicate ​balance of strength and functionality that works for YOUR MIRACLES OF BIOLOGICAL ARCHITECTURE.
