The risk of the Tyndall effect occurring with Belotero is extremely small.
As you may know, the Tyndall effect is a phenomenon in physics. Light rays will scatter when they pass through a clear solution where small particles are suspended in. This scattering will produce a bluish color.
What’s special about Belotero is that the gel is not a suspension of particles. The hyaluronic acid molecules are processed differently. When Belotero is injected, it creates a very smooth layer beneath the skin. It will not behave like particles. It is less susceptible to clumping and Tyndall light refraction.
Besides the tear troughs, it can also be used to fill fine lines like this patient.
