You can’t buy these (as they come with your purchase of the large-sized SK-II Treatment Essence at the brand’s counters in Seoul) but these are the best facial cotton pads on the market. Soft, lightweight, and anti-pilling–I never thought I’d rave about cotton pads. In addition, unlike using cotton balls, there is very little waste of product. And, rather than using them with quick swipes (as you would with cotton balls), you “pad across” your face using the pads, which can help prep your skin for the next product (i.e, serum, moisturizer, etc.). Don’t use SK-II products? Get a friend who does and offer to pay for the pads–they’re worth it!
