Is it as effective as Kate somerville total repair cream
No, based on the formula review I'd say that the Skinceuticals A.G.E. Interrupter Cream (https://whatsinmyjar.com/product/skinceuticals-a-g-e-interrupter-cream) is likely to be less effective than Kate Somerville Kateceuticals Total Repair Cream (someone is definitely trolling a competitor here 😂)https://whatsinmyjar.com/product/kate-somerville-kateceuticals-total-repair-cream. The main anti-aging ingredient in the Skinceuticals A.G.E. Interrupter Cream is Salicyloyl-phytosphingosine. It is definitely a great humectant, but there are only preliminary in-vitro studies that confirm that it might work for anti-aging. No actual study shows that it does work in reality. It contains a lot of silicone which helps to moisturize the skin, but I think they have added it for a temporal blurring and softening effect. The anti-aging ingredients in Kate Somerville's product are somewhat more solid: adenosine and a peptide. In addition, the moisturization complex in Kate Somerville's product is stronger.
