I recommend using serums that contain Hydroquinone which is a skin lightening ingredient. A small amount applied consistently to the skin will naturally lighten dark spots. Also, remember to continue to apply sunscreen during the day to prevent spots from getting darker.
The Murad Rapid Age Spot and Pigment Lightening Serum works great as a night treatment.
-Hydroquinone (2.0%): Fades existing dark spots, age spots and freckles.
-Hexapeptide-2: This advanced skin lightening peptide complements the results of hydroquinone and prevents future damage by helping prohibit pigment formation.
-Glycolic Acid: Exfoliates to remove dead skin cells, helping the active ingredient to penetrate more quickly for faster results.
