An absorbent article comprising: a liquid permeable topsheet; a liquid impermeable backsheet; an absorbent core comprising an absorbent material and a core wrap, wherein the absorbent material is sandwiched between a top side and a bottom side of the core wrap, wherein the absorbent core comprises at least one channel-forming area that is substantially free of absorbent material, and wherein the channel-forming area forms a three-dimensional channel when the absorbent material swells; a masking layer between the absorbent core and the backsheet; wherein a wearer-facing side of the masking layer and the bottom side of the core wrap are only partially bonded to each other, their interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion, so that the masking layer can at least partially decouple from the three-dimensional channel when the absorbent material swells so as to at least partially conceal the three-dimensional channel when the absorbent material swells.
