Elizabeth Arden Intervene Skin Tone Perfecting Capsules are for achieving radiant looking skin. Each vitamin C packed capsule works all night long to help reverse the effects of stress & sun damage, dullness caused by age spots, discoloration, even the dark traces left by acne. The bottle contains 37 capsules. When I was using these capsules, I noticed a visible difference in my skin tone. It faded some of the dark spots I had, and there was an overall improvement in my skin tone. The product is pricy but the bottle lasts for 37 days (1 capsule a day). I prefer to use these capsules at night.
