Thank you for your question. You are describing a Tyndall effect, which occurs when Juvederm is injected too superficially, it's a light scattering effect. A chemical peel will not cause the area to turn blueish.
You should wait about 2 weeks after having Juvederm before having a chemical peel to allow the filler to settle and any bruising to resolve. A chemical peel will not cause the filler to turn blue. If the filler is placed too superficially in the skin, the reflection of light gives it a blue appearance. It can be dissolved with hyaluronidase.
