Yes, the forgotten Vaseline in the bathroom cabinet will help you say goodbye to those dry heels. It’s the easiest way to deal with those cracks. Vaseline protects the skin of the heel, prevents moisture loss and softens the skin so it stretches sufficiently.
You can apply it at any time on your heels. But it is better to apply it after soaking and rubbing your feet. Gently massage the cracked heels until the skin absorbs it. Cover your feet with a pair of socks and leave overnight. Repeat the massage daily until the cracks are healed.
