Foot concern
Cracked heels & calluses
Hyperkeratosis
Thick, hard skin and splitting heels — why moisturiser alone doesn't fix it, and what does.
What it actually is
Calluses are the skin's response to pressure: it thickens where it's loaded. On the heel, that thickened rim loses flexibility, and when the pad spreads under body weight it splits rather than gives — producing fissures that can be deep enough to bleed and genuinely painful to stand on.
Why it happens
- Standing for long periods, especially on hard floors
- Open-backed shoes and sandals, which let the heel pad spread sideways
- Naturally dry skin, and skin that's drier with age
- Altered gait or foot shape concentrating pressure in one area
What tends not to work
Moisturiser alone rarely resolves an established crack, because it can't penetrate a thick keratin rim — the hard skin has to be reduced first for anything to reach the living tissue underneath. Foot files and pumice used aggressively tend to make things worse over time: the skin responds to the trauma by thickening further.
How we approach it
The thickened tissue is reduced professionally, with sterile instruments, down to comfortable skin without going too far — over-debriding creates a new wound. From there it's about what's causing the pressure in the first place, plus a realistic home routine using a urea-based product rather than a standard body lotion.
When to see a doctor instead
See your physician if a crack is bleeding, discharging or surrounded by redness — and immediately if you are diabetic, where an open heel fissure is a wound rather than a cosmetic complaint.

Questions
Cracked heels & calluses — common questions
- Why do my heels keep cracking even though I moisturise?
- Usually because the thickened rim is too dense for moisturiser to get through, and because the pressure causing it hasn't changed. Reducing the hard skin professionally, then maintaining with a urea-based cream, addresses both halves.
- Can I just use a foot file at home?
- Gentle maintenance is fine once the bulk has been reduced. Aggressive filing tends to backfire — skin reads repeated trauma as a reason to thicken further, and it's easy to take off more than intended.
