Will tretinoin damage Restylane and Radiesse fillers?

Topical tretinoin or retina-a should have no impact on your injectable filler. You might get some redness using the retina-a which is normal and some peeling but other than that your filler should be ok. 

Tretinoin is applied topically and does not affect any deep layers below the epidermis. So any type of fillers are not affected by tretinoin.

Tretinoin will not affect fillers which are injected into the skin. Using tretinoin will prevent superficial wrinkles and therefore is a must in anti aging skin care.

Thanks for your question and as a dermatologist we routinely recommend retinoids as topical therapy for skin aging and photodamage.  Fillers are injected deeper in the skin than most retinoids will penetrate and may enhance the results over time so find the right provider and learn all there is to learn about fillers and good skin care.

Tretinoin will not have any impact on fillers, but can be an important component of a good skin care regimen.

Not at all - retinoids are an important part of any anti-aging skincare regimen and should be used in conjunction with procedures, such as filler, for the most youthful appearance.  

The short answer is no.  Tretinoin may actually enhance the collagen production of the fillers over time

Tretinoin is only topical, whereas Fillers are usually placed deep into the dermis. Using Tretinoin will not affect Restylane, Radiesse or any other filler.
