The Crème de La Mer Duet (Limited Edition)

What you are looking at is The Crème de La Mer Duet (Limited Edition), a skincare product. 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. Where one is discounted, compare the size and edition rather than the headline alone. 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.
