I used these two serums before from Luxury set, really really easy to absorb and love the texture, but still could not see the result because of the size.
This year serum duo amazing discount so I order 6 sets, use the blue one with double potion because of winter, and the pearl one I can see the pearl inside bottle just mix with serum while I press it out, really really fresh. After 2 weeks my skintone looks brighter and the lines improved.
Hope next year will promote this duo.
