A dermatologist who helps women look their best is sharing her secrets for healthy, youthful skin. Dr. Sonia Batra says the questions she gets from patients often depend on their age. One of the products she recommends to these women is a serum from No7 called "Lift and Luminate Triple Action Serum." Dr. Batra said she enjoys the product because it has three clinically proven results. She said it evens out skin tone and visibly firms the skin.
