Erthskin London Vit.C+Collagen serum

Erthskin London VITAMIN C + COLLAGEN ELIXIR SERUM

Opened in summer, but selling because I was gifted another product, which is a concentrate and should be more effective in fighting my dark pigments, and mixing products is not possible. At least half is left. The line is indicated in the picture, but it might be slightly more, as after shaking, the product hasn't completely drained from the bottle walls. Original price 75€, I bought it on sale.
