Back in 1991 leading NY cosmetic dermatologist, Dr. Howard Sobel, created a skincare line that was ordered by skin concerns, not skin type. In 2007, P&G acquired the brand and started using that amazing global expert network of theirs to further grow the brand. DDF now has five core lines, each targeting a specific concern: acne, hyperpigmentation, sensitive skin, preventative anti-ageing and restorative anti-ageing. Two hero products stand out: Wrinkle Resist Plus Pore Minimiser Moisturising Serum ($124.95)—the number five best-seller in Sephora has a dual-phase technology that provides instant gratification and future treatment in the war against wrinkles and pores; plus it's a good primer. And Discolouration Reversal-Pods ($104.95) provide a targeted treatment to discoloured areas or age spots.
