I have used 2% hydroquinone products w/zero help for sun spots. I started retinol .05, is this enough? (Photo)

You may want to consider prescription strength hydroquinone and topical retinoid at this point given you haven't seen the results you are looking for with the over-the-counter strength products. I typically recommend the Obagi Nu-Derm hydroquinone products combined with tretinoin to address concerns such as yours. When treating hyperpigmentation, it's also critically important to be diligent with your sunscreen use. I would suggest scheduling a consultation with a dermatologist in your area to discuss your concerns and these possible solutions.
