The freshest aloe is of course, from your own plant. Apply aloe gel directly to skin for cooling relief to dry, itchy skin, minor burns and rashes.
Commercial aloe skin care products (containing stabilized aloe) rarely, if ever, pack the therapeutic punch of fresh aloe because they no longer contain any tannins, and are mostly adulterated with alcohol.
You can also incorporate aloe in homemade lotions, and use it as a carrier for essential oils. Add a few drops of Chamomile and/or Lavender oil for burns and scalds.
