Is tea tree oil good for age spots?

I would opt for more therapeutic options. Start with the Kareskin Brightening Kit with Melarase followed by Clear and Brilliant laser and light chemical peels. Best, Dr. KaramanoukianLos Angeles

Over the counter products (like oils, etc) may not correct age spots in the face.Age spots should ideally be treated by an skin care specialists like a board certified plastc surgeon.There are multiple medical ways to improve age spots in the face, both non-invasive and minimally invasive. In my practice, most of the patients prefer to correct age spots in the face with Obagi Nu Derm Skin Transformation System. "Obagi" as commonly known, is a medical grade cream system that improves/corrects age spots in the face with minimal downtime. When guided like I do in my office, the results of Obagi are exceptional to the point that every patient that comes for his final evaluation very often brings me her/his spouse, friend or relative for Obagi treatment. Patients interested in age spot management should make a consultation with a Board Certified Plastic Surgeon specialized in skin careJohn Mesa MD

While tea tree oil is anti-microbial and anti-fungal using it to treat age spots may not be as effective as retinol with hydroquinone or Lytera which is all natural skin brightening cream by Skin Medica.  Lytera uses kojic acid, licorice root and small does of retinol to reduce the appearance of age spots.In addition, we suggest Alex Tri-Vantage laser by Syneron-Candela treatments or SRA handpiece on their elos Plus platform for IPL photofacials to improve the appearance of the age spots.If you haven't considered chemical peels I recommend the VI Peel or a series of Vitalize or Rejuvenize peels for great results on age spots.Always remember to use sunscreen all year round.  We recommend our broad spectrum physical defense by Elizabeth Arden Pro SPF 50.  It has moisturizing DNA enzymes.Hope this helps.  Good luck!
