I really like the versatility of the loofah discs. Each loofah disc has varied areas of roughness. I have sensitive dry skin that doesn't handle exfoliation well so I use a softer part of the loofah disc to gently exfoliate my face once or twice a week. If there is an area that needs more exfoliation I can easily find a rougher part of the loofah disc to handle it.
I have tried many different types of exfoliation metods (clairsonic, scrubs, facials, etc.) but I think these loofah discs are the best I have found as it gives me more control on how rough or soft the exfoliation is and I don't have to buy multiple products to get the same control.
