Curious about buying your own lava stone? While browsing, check the pore size:
"The pore size of the stone determines how exfoliating the stone will be," explains Patel. Smaller pores mean gentler exfoliation, which is best for elbows and knees. On the flip side, larger pores are great for callused hands and feet, as those tough areas may require rougher exfoliation. Some market options are even double-sided, with one abrasive side for rougher skin and one softer side for more sensitive areas.
