The Tyndall effect was first discovered by (and is named after) the Irish physicist John Tyndall. The diameters of the particles that cause the Tyndall effect can range from 40 to 900 nanometers (1 nanometer = 10-9 meter). In comparison, the wavelength of the visible light spectrum ranges from 400 to 750 nanometers. Examples of the Tyndall Effect

Tyndall effect: “The phenomenon of scattering of a beam of light by colloidal particles, when passed through a colloidal solution, is called the Tyndall effect”. When light is passed through a colloidal solution, it is observed that the colloidal particles do …

Faraday first observed this effect and was further studied by Tyndall that’s why it is called the Tyndall effect. Tyndall cone can also be observed which is the bright cone of light. The path of the beam is illuminated by the scattering of light in the colloidal dispersion. If these two conditions are satisfied then we can observe Tyndall effect:

Oct 14, 2012 · The Tyndall effect is a bluish discoloration that appears if hyaluronic acid fillers are injected too superficially into the skin. The filler is a clear gel so when light reflects through it through the skin it appears bluish. It is possible that what you are seeing is the Tyndall effect.

Apr 8, 2010 · The Tyndall effect refers to a bluish color from small particles reflecting light in a transparent medium. Sometimes the hyaluronic acid fillers when injected into a superficial position can cause this bluish color. It will last for the duration of the filler's presence, although it may lighten as the particles of the filler lessen.

The first picture looks like a bruise (was this taken earlier?). After 5 weeks one would not expect to still see a bruise. Judging from the second and third photos I vote for Tyndall effect (which is actually a bluish color under the skin due to light reflecting over the filler).

Aug 29, 2008 · The Tyndall effect is avoided by injecting hyaluronic acid fillers below the muscle when filling a lower eye lid hollow. I, too, hope that when your swelling goes down, the "bruised" look goes away. Good luck and be well. By the way, have you looked in your mirror lately, your picture looks feline, I haven't heard of that side effect yet. Dr. P

The phenomenon by which colloidal particles scatter light is called Tyndall effect. The particles of colloids scatter a beam of light passing through it and make its path visible. True solutions do not show Tyndall effect. Scattering of light or Tyndall Effect …

Tyndall effect: The phenomenon in which the solute particles of a colloid scatter the beam of light and show its path is called the Tyndall effect. The colloidal solution has the property of the Tyndall effect. For example, a starch solution which is also a …

Apr 17, 2018 · Both products, Restylane and Juvederm can result in the Tyndall effect or migration of the filler towards the nose underneath the eye. When that happens the patient needs to receive a series of injections of the product called hyaluronidase which will dissolve the hyaluronic acid.
