Can I turn my face color back to normal after using a rejuvenating set?

Thank you for your question and the photo.Once you have stopped using the skin brightening products your skin will go back to it's normal skintone.There are lots of treatments such as skincare, SkinPen medical needling, peels and laser treatments that can give you an even skin tone without over brightening your skin.

discoloration can be improved with at home cosmelan peels and the right skin care treatment plan -- photo plus, vitamin c, bio clear cream, retinol, vivatia, hydroquinone and growth factors like anteagemd.
Hyperpigmentation from any type needs a combination approach of peels like cosmelan,  lasers like clear and brilliant and aerolase or laser genesis, radiofrequency like venus viva, and constant skin care and sun protection.  Bimontly facials with silk peel dermalinfusion is essential to hydrate, exfoliate and infuse vitamins and antioxidants into the skin.  If you have acne you can do additional treatments and peels to get more improvement.  I suggest a formal consultation with an expert in lasers and peels. Best, Dr. Emer.

There are many reasons why the skin darkens which may include sun exposure, inflammation, existing skin conditions, medication, genetics, friction, etc. There are many ways to lighten the skin including lasers and peels. For skin damage due to inflammation which may be the case here, I advise strongly against self-medicating. Ask your doctor for an appropriate treatment plan to possibly reverse any damage. IV therapy may also be helpful for you. It involves directly injecting a concoction of vitamins and minerals into your bloodstream. The concoction will be tailored by the doctor depending on your needs which for this case is skin lightening.
