The filler product used for tear trough filler is very thin and watery,t The skin under the eye is different to the skin of the rest of the face, there are only three layers compared to the normal four, this makes the tear trough region quite technologically sensitive to treat, Treatment must be subtle as to avoid the risk of lumps or bumps under the eye. The filler used in this region is very thin and watery and takes roughly two weeks to absorb the body's natural own water supply to be at its maximum 'plump'. At this point, if the results are still not at their optimum, we will offer a top-up treatment at a cost price (£100) for any additional filler to be placed.
