Hyperpigmentation After Having Restylane in Nasolabial Folds

Given your description you are likely a darker Fitzpatrick skin type maybe IV.  The higher the number the darker the skin.  People with darker skin are more likely to develop what we doctors call "postinflammatory hyperpigmentation".   This is not likely related to the Restylane itself but to the repetitive trauma to the skin which is the needles in the skin during Restylane injection.   This will most likely resolve in time on its own but to speed its resolution you may want to apply either Triluma cream or try retin-A and hydroquinone.   You may want to discuss these options with your doctor.  Hope this helps!

you have noticed darkening in the skin after Restylane in your asian skin. Is this pigmentation? Is the color not pigment? The diagnosis may be incorrect if in fact, the color is the Tyndall effect in which Restylane or Juvederm could cause the light waves to reflect differently and appear blue. This bluish coloration may be misinterpreted as pigment. If it is the filler it can be expressed by the doctor or dissolved by injections of hyaluronidase.  If it is postinflammatory hyperpigmentation, than you may get improvement with prescription lightening creams. Also consider very tiny needles and gentle technique with the next treatment, although some people have skin that no matter how gently it is treated, their pigment increases after any treatment. Sunscreen is important.

The hyperpigmentation is caused by the inflammation from the glycolic peeling agent.  Stop using this product.  Post-inflammatory pigmentation usually but not always resolves with time.  The reason this pigmentation wrecks the filling effect of the Restyalne is that darkness suggests depth.  So the pigmentation in the nasolabial fold suggests depth here.

It’s possible to get hyperpigmentation after Restylane injections just like with any needle stick. You really want to stay out of the sun and use a sun block (like you’re doing). In general, the hyperpigmentation will go away in time. Using a bleacher like a 4% hydroquinone can also be helpful.

If Restylane is injected too high it can result in bluish color, creating what is called the Tyndall effect.  If that 's the problem, it can be dissolved with an injection of hyaluronidase.  If the discoloration is brownish in color this is what we call post-inflammatory hyperpigmentation - and the cause of the problem can be from the needle pricks which took place as a normal part of the treatment process. This problem is more common with people with an olive skinned complexion -- best to stay out of the sun, and use over the counter cortisone cream.  If the condition does not improve, see a dermatologist.
