The Tyndall effect in cosmetology is a complication after contouring, which occurs as a result of too superficial injection of predominantly dense hyaluronic acid fillers and manifests itself in the form of a bluish tint of the skin over the preparation.
Factors that influence the likelihood of this complication occurring:
- the skill of the doctor performing the procedure;
- introduction technique;
- specific features of the treated area;
- injectable drug.
This article estet-portal.com will focus on diagnosis, therapy and risk minimization appearance of the Tyndall effect after hyaluronic acid injections.

How to recognize the Tyndall effect: signs and symptoms
Tyndall effect is caused by too superficial filler injection or large boluses of hyaluronic acid.
Due to the bluish tint of the skin, this complication can be mistaken for a deep hematoma. However, unlike a hematoma, the Tyndall effect does not go away a few days after the procedure.
Skin discoloration can be subtle and almost invisible in low light. Often, the problem area is characterized by a certain degree of elevation or bumpiness due to superficial injection of the gel.
The Tyndall effect can persist for months or even years.
If no corrective action is taken, the Tyndall effect can persist for months or even longerm.
In which zones does the Tyndall effect most often occur after the introduction of HA
The Tyndall effect is more likely to occur when a hyaluronic acid filler is injected into areas with particularly thin skin.
The cause of thinning of the skin, whether it be anatomical features, diseases or age-related changes in the area being corrected, does not matter.
This complication is most often seen after tear trough correction and perioral wrinkles (smoker's wrinkles).
However, Tyndall effects have also been documented due to improper injection of hyaluronic acid into the nasolabial foldsand.
Tyndall effect: how to prevent a complication
How to minimize the risk of complications after filler injections
It is the doctor's responsibility to inform the patient of the likelihood of this and any other complications prior to the procedure.
Information about the possible consequences of correction with HA fillers should be included in the consent process, especially before working on potentially hazardous areas.
Before drawing up a correction plan, the thickness of the patient's skin must be taken into account. It may be advisable in some cases to refuse to inject the filler into areas that are characterized by exceptional thinness of the skin.
Proper technique and depth of injection play a decisive role in preventing the Tyndall effect.
For example, in the region of the nasolacrimal sulcus the filler must be injected at the level of the periosteum or at least in the infraorbital plane.
The doctor should also inject minimal aliquots of hyaluronic acid and avoid injecting large boluses of the drug in hazardous areas.
Effective techniques for safe correction with hyaluronic acid fillers
Practitioners, based on their experience, agree that when dermal fillers containing large particles are incorrectly injected, the Tyndall effect occurs more often than when working with other drugs.
In particular, we are talking about gels of stabilized hyaluronic acid of non-animal originI (NASHA).
What to do in case of Tyndall effect
To redistribute a gel that has been injected too superficially or in excess, in some cases it may be enough to deep massage on the problem zone.
The effectiveness of this method directly depends on the intervention time.
Ideally, the Tyndall effect should be diagnosed and the massage should be performed immediately after the administration of the drug, since in a couple of days it will most likely be impossible to eliminate this complication by means of mechanical action.
Safely injecting fillers: how to prevent possible complications
Tyndall effect can also be eliminated by partial or complete removal of injected HA filler by:
- a stabbing incision with an 18-gauge needle, followed by extrusion of the preparation;
- aspiration with a needle and syringe;
- incision and drainage;
- 1–2 mm incision in the central part of the problem area with a size 11 scalpel followed by extrusion of the filler with 2 cotton buds.
However, hyaluronidase injections are the most common way to correct this complication. Often it is hyaluronidase that provides complete elimination of the problem within 24 hours.
True, in some cases, it may be necessary to re-injection of the enzyme. The dosage varies (from 30 to 75 units) depending on the amount of HA in the problem area and the amount of filler to be removed.
Hyaluronidase can be used to eliminate the Tyndall effect at any time, even 63 months after the administration of hyaluronic acid.
There is a limited amount of data that supports the use of Q-switched Nd:YAG laser
to eliminate the Tyndall effect.The expert group refrains from recommending this method due to insufficient data and an unknown mechanism of action. !
If the patient categorically refuses any intervention by the practitioner, the discoloration can be concealed by means of make-up.
