Choose based on your primary use: skin care, aroma diffusion, or blending into personal routines. For ready skin care, Hanso Moisturizing Spa Gel Socks combine Jojoba Oil, Olive Oil, Vitamin E and Plant Essential Oils to help soften dry heels and improve suppleness. If you’re after aroma or therapeutic diffusion, consider pure essential oils in bottles such as Clove, Basil, Marjoram, or Tea Tree in sizes like 15 ml or 30 ml for diffusers or custom blends. When applying any essential oil to skin, always dilute with a carrier oil first, for example jojoba, almond, or olive oil.
