One of the products that is is universally recognized to be in Kate’s Royal Beauty Bag is the Swiss skincare line Karin Herzog. Using patented oxygen technology, Karin Herzog’s products are designed for all kinds of skincare regimes, but perhaps the most popular are their anti-aging capabilities which are the products Kate uses. We have covered the Karin Herzog line before in the Royal Beauty Bag series, but testing out one product versus the entire line is a very different scenario, so we were excited to test out the Karin Herzog Oxygen Facial Kit and get a sense of the whole regimen that Kate trusts her complexion to.

The Royal Oxygen Facial Kit contains 4 steps to revealing princess-like skin – prepare, correct, treat and nourish. The kit is designed to be used morning or evening, or whenever your skin is in need of a bit of Princess pampering – extremely helpful in developing a high-performance anti-aging regimen to promote collagen production, diminish wrinkles and lift sagging skin. I tested it out and share all of the steps.
Step 1 : Prepare with a Mild Scrub
One of the most important steps of any skincare routine is making sure you start with a clean base. Scrubbing off makeup and dead skin from the top layer of skin allows you to get to the healthy skin underneath that needs to get the creams, potions and serums you are putting on. The Royal Oxygen Facial Kit contains a gentle, luxurious exfoliant to reveal a more radiant complexion in the Karin Herzog Mild Scrub (1.7 oz). As someone who loves scrubs and exfoliants, I was perhaps most excited to test out this product and compare it to the wide variety of other products in this category that make up my beauty arsenal. KH’s mild scrub surprised me in a good way; the scrub came out looking really thick in a white liquid, but when it was rubbed onto my skin it was amazingly gentle. There is a difference in my books between gentle and effective, but with almost round beads as the exfoliant, it didn’t cause any redness or irritation after using it.
Pro Tip: Massage a hazelnut size amount onto a thoroughly cleansed face using a circular movement for 1 minute. The scrub works best if you mix a few drops of water with it in your hand or on your fingers before applying it as it will make it easier to spread. I wet my hands after about 30 seconds and then continued to scrub in the mixture for another 30 seconds, making sure that I reached all areas of my face.
Step 2: Correct with a Powerful Serum
So you’ve cleaned off your face and have got your skin prepped for the next step – which is to take steps to correct the damage that modern day life have caused to your skin! The Royal Oxygen Facial Kit comes with the Karin Herzog Erase & Raise Serum (0.5 oz), a potent lifting and anti-aging serum, formulated with hyaluronic acid and Vitamin E, which helps to increase the water content in the skin and boost collagen production. I loved this serum as it was almost immediately absorbed into my skin and didn’t leave it feeling greasy or weighed down.
Pro Tip: Shake the bottle well and massage a few drops into the skin. It is safe to use on the skin around the eyes. Allow to dry for one minute.
Step 3: Treat with an Essential Mask
Masks are a critical part of any skincare regime as they allow your skin time to absorb all the good nutrients and helps propel the E&R serum from step 2 into the deepest layers of the skin where it can have the best effect – so don’t skip it! The Royal Oxygen Facial Kit comes with the Karin Herzog Facial Mask (1.7 oz)
Pro Tip: Use the small brush included in the kit to apply a medium to thick layer on top of the dry serum. Leave on for 10-15 minutes and massage in any excess. I left it on overnight for the dramatic results that the bottle advertised and I was not disappointed. It’s not sticky and absorbed to a dry state quickly, so it didn’t get all over my sheets or pillowcases either, bonus! It’s also safe to use around the eyes so you can make sure your delicate eye area gets bonus nutrients!
Step #4: Nourish with an Intense Moisturizer
The last step in the process is to add a deep moisturizer to help lock in all of the benefits your skin has experienced over the previous steps and to create a barrier against external elements. The Royal Oxygen Facial Kit comes with the Karin Herzog Additional Sweet Moisturizer (1.7 oz) which is an intensive moisturizer. It goes on really light but you can absolutely feel the richness of the cream and my skin felt amazing immediately after using it.
Pro Tip: After the mask has absorbed, massage the hazelnut size amount into the skin, in circular movements.
Overall, I loved this kit. Love, love, love it. It’s one thing to test out a single product in a line, but testing the entire line is how you can really get a sense of the quality and overall impact of a line. I can absolutely see how Kate appreciates the luxury of the products – from the packaging down to the actual scrubs, serums, masks and moisturizers themselves. The full Royal Oxygen Facial Kit is $219 ($269 value) available from Karin Herzog.
