Selphyl for Under Eye Area w/ Thin Skin

Is Selphyl good around under Eye with Very Thin Skin and Brow area. I heard the Doctor has to use a Big Needle to inject.How deep does it get injected. Does Selphyl give any Lumpyness or Bumpness like Fat grating or HA Fillers.Or Does it come out smooth.I can see spider Vein under my lower Eyelid skin. Would Selphy help make the Skin thicker or help improve the Skin area where it is injected.since it has the Nutrients from the Blood. How long does it last. Any Risks or Side Effects?
