What is it: A powerful antiaging duo from Kate Somerville featuring DermalQuench Liquid Oxygen Treatment and RetAsphere 2-in-1 Retinol Night Cream.

DermalQuench Liquid Oxygen Treatment is a scientific breakthrough in antiaging technology that produces both immediate and long-term results. This unique formula, inspired by the most sought-after treatment at the Kate Somerville Skin Health Experts Clinic, aggressively combats the look of visible signs of aging: wrinkles, uneven tone, and dryness.

RetAsphere is a rich nighttime cream that effectively diminishes the appearance of crow's-feet, wrinkles, and expression lines while keeping the skin looking and feeling hydrated, smoother, and firmer.

Who is it for: Anyone, with any type of skin. It's ideal for those who would like to help improve the appearance of the signs of aging and help reduce the appearance of wrinkles.

Why is it different: The unprecedented DermalQuench delivery system infuses skin with the three sophisticated ingredients in the advanced HydraFill complex. PFC-Oxygen carriers deliver oxygen to the skin; fast-penetrating hyaluronic acid provides intense, long-lasting hydration; and botanical extracts and vitamins increase the look of radiance.

The RetAsphere Smart Release Carrier System delivers retinol in a lipid shell that distributes evenly into the skin.

How do I use it: Use DermalQuench morning and evening. Shake well and prime applicator by spraying three times away from face. Dispense two to three stripes on the right side of the face--cheekbone, mouth to ear, and jaw line--and immediately massage in. (Avoid contact with eyes and lips.) Repeat on the left. Dispense one stripe across the forehead and immediately massage in. Follow with your typical regimen.

Use RetAsphere in the evening only. Apply a thin, even layer to face. Reduce the frequency of use if sensitivity occurs. While using this product, also use a daily sunscreen (not included).

From Kate Somerville.

Reviews & Community QA

Kate Somerville DermalQuench & Retasphere Duo is rated 2.5 out of 5 by 2.
Rated 2 out of 5 by from Not as expected I have tried Kate Somerville products in the past and have been pleased with them. After all of the talk about the dermal quench, I thought I would try this set. Unfortunately, I found both products to be very average; especially for the high price. The dermal quench dispenser is awkward to use and is nothing more than just a serum, not even as good as her regular quench serum. The retinol product has an odor at first but then dissipates quickly, thank goodness. I gave away the dermal quench hoping that someone else may find it beneficial for them. I am keeping the retasphere because it doesn't hurt to have an extra retinol product on hand and it will be easy to travel with.

Rated 3 out of 5 by from Prefer the Retinol Product See some results from the Retinol Night Cream....Although, am not sure it's any better than Roc brand, and it's MUCH pricier. Not impressed w/the Dermal Quench...I prefer Dr.Defenses Moisture Lock treatment (seems like an oil, but readily absorbs...It's fabulous!) (I am 57/y.o. with Combo skin...Dry mostly, w.oily "I" zone)
