How long does SeneGence skincare take to work?

Quick answer

Some SeneGence skincare shows results from the first use, and the rest builds over weeks. In an independent eight-week study, the Normal-to-Dry 3 in 1 Cleanser, DayTime Moisturizer and Evening Moisturizer, used together as a regimen, improved measured hydration by 49.99% immediately after application. Treatments keep their own timelines. In an independent study, GLP Complex™ with SenePlex+® and Exosomes reduced the appearance of deep wrinkles by 23.4% at eight weeks. See the regimen study or the GLP Complex study.
