Tyndall effect: the bluish tint after filler
The Tyndall effect is the bluish or grayish color that appears in the skin when hyaluronic acid sits in a very superficial plane. The name comes from the physical phenomenon in which particles scatter light: blue light is scattered more by the gel and returns to the observer's eyes, giving the characteristic tint.
It is more common in areas of thin skin, especially the tear trough and the lower eyelid, and it can also appear in folds and lips when the product is placed superficially. The type of gel and the volume also play a part.
How do you tell it apart from a bruise?
A bruise changes color over the days (purple, green, yellow) and disappears within one to two weeks. The Tyndall effect keeps a stable bluish tone, sometimes with a small bump at the site, and does not improve with time in the same way. Photos in good light help track the difference.
How is it usually corrected?
Because the problem is the position of the product, the usual correction is to break down the gel with hyaluronidase, at the discretion of the qualified professional. In mild cases, some professionals consider other approaches, but the enzyme is the most cited option.
Prevention comes down to choosing the right product, plane and volume for thin-skinned areas, and to assessing the indication carefully, especially around the eyes.

Frequently asked questions
Does the Tyndall effect go away on its own?
