This is the main difference between Revanesse and ReDexis:

ReDexis is still pure stabilised cross-linked HA (like Revanesse), but it contains dextronomer beads aswell. These help the tissue to grow its own collagen and this plumps out deep lines better and because the collagen that is produced is from the body, it will not break down quickly so it lasts longer (18 months).

But, ReDexis cannot be used in the lips because you do not want to make collagen forming in the lips. This is why you should use Revanesse or Revanesse Ultra in the lips:

Revanesse (used anywhere, mainly fine lines and lips) - 6 months
Revanesse Ultra (thicker, used for deeper lines and lips) - 12 months
ReDexis (used for very deep lines, nasolabials etc.) - 18 months
ReDexis Ultra (used for very very deep lines or for sculpting nose, cheek or chin areas) - 18+ months
