Meet The Duo: Hydration + Protection, Perfectly Paired
Quench and Shield—like the ultimate skincare power couple—designed to hydrate, protect, and leave your skin glowing. This dynamic duo delivers deep hydration and barrier protection in just two easy steps. Because skincare should work hard for you, not the other way around.
Start with Quench Hydrating Serum to flood your skin with moisture and boost radiance. Follow with Shield Face Oil to lock in hydration, brighten your complexion, and defend against environmental stressors.
Bonus: Comes with a reusable, logo-printed canvas drawstring bag—making it the perfect gift for beauty lovers or a well-deserved treat for yourself.
Why You’ll Love It
-
Two Steps, One Glow: Hydration + protection in a simple, effective routine.
-
Deep Hydration:Snow mushroom in Quench is a natural source of hyaluronic acid, holding up to 500x its weight in water for plump, dewy skin.
-
Brightening + Balancing: Niacinamide in Quench regulates oil production and reduces hyperpigmentation, while Shield’s Vitamin C and Bakuchiol brighten and smooth.
-
Barrier Boost: Quench replenishes hydration, and Shield locks it in with Squalane and essential fatty acid-rich oils for lasting softness and resilience.
-
Plant-Based Retinol Alternative: Bakuchiol in Shield delivers retinol-like results (smoother texture, fewer fine lines) without irritation.
-
For Face & Gift-Ready: Includes a reusable canvas bag, making it a thoughtful gift or travel-friendly set.
Why The Duo Stands Out
Skincare doesn’t have to be complicated to be effective. The Duo gives you everything you need for hydrated, resilient, glowing skin in just two steps. Powered by snow mushroom, mandelic acid, bakuchiol, and vitamin C, this set simplifies your routine while delivering serious results.

Let customers speak for us
from 47 reviewsI have been using the Trio since they all first came out and I don’t ever want to use anything else on my skin. It is a perfect and complete regimen. Angela is a skin wizard.✨
This stuff makes me think about washing my face in a longing way, like, ooooh I can’t wait to wash my face later. On my third reorder so you know its real.
I have been using Cult of Reason products since Grit first appeared on the market. I love this natural 'scrub'. Adding Quench and Shield to my daily routine has changed the texture of my skin. I'm 73 and my skin looks like that of a 30 year old....
Shield, Quench, Hydrating Face Masks or any Cult of Reason product seem to not only help my skin and face glow and thrive — they leave me feeling calmer and ready to face the changes in life. True! Barbara
I've recently started using these products and I LOVE Quench! It lives up to it's name and makes my skin feel - and look - great. I'm a mid 50s something woman who was looking for something to freshen and liven up my skin. I've found it. I started off with The Duo product set
The products are phenomenal. Angela is a perfectionist. She has created a product that works for all skin types. Cult of Reason has become my go to product.
Amazing product. More than worth the price. Smells and feels amazing; hydrates better than any lotion I’ve tried.
I have been using Cult of Reason products for several years and highly recommend them. I particularly love Grit but I also love Quench & shield. Definitely a good value for the high quality!
The quench product is the absolute favorite preference by my wife. This year we purchased two as the product and delivery surpasses expectations! We will visit Cult of Reason again in the future.
Grit has changed my whole routine. From helping with my acne prone skin to essentially healing the KP on my legs, i will be a customer for life. This line of product is amazing.
Why it works
These two products are the dynamic duo of skin moisture barrier support. When used together they make a complete moisturizer for combination skin. Quench is like a water fountain and Shield is the occlusive sealant that keeps the water content in the skin.

Love these products. Easy to use and effective. And “clean” ingredients. A must have, go to!
I love the quench and shield duo. I have been using the quench for about a year now and recently started applying the shield on a daily basis. Great combo for my dry aging skin. My skin appears brighter and certainly more hydrated. Thank you, Cult of Reason!
You’re absolutely welcome! Thanks for taking a moment to share your experience with Quench and Shield.
I reach for these excellent products over and over! They work like a dream and smell fantastic to boot. If you're wondering whether they are worth it, don't hesitate—they are! And I say this as a spa owner!
