The Kissu Lip Mask

The Kissu Lip Mask by Tatcha is a skincare product, filed under Skincare. Active ingredients can be effective and irritating at the same time, which is why the usual advice is to introduce one at a time. Apply to clean skin and give each layer a moment to absorb before the next — a rushed routine mostly pills. Whether it is discounted this week says more about the shop's stock than about the product. Follow with SPF in the morning: plenty of active ingredients leave skin more sensitive to sunlight than usual. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
