Hi,

Well, you'll want something with Carrot Seed essential oil - which is great for both the skin and the liver - the reason the brown spots appear at all. You can certainly work with our Heavenly Skin serum, or something more simple such as our Super Skin Care base carrier oils with a 3% concentration of Carrot Seed (that's about 30 drops in each one ounce of carrier oil). The Super Skin Care Base is exceptionally nutritive, and will likely offer dramatic improvements in skin texture and appearance, even with only the addition of Carrot Seed.

All the Best,
Eric
