A moisturizer is a cosmetic product designed to increase skin hydration, reduce transepidermal water loss (TEWL), and support skin barrier function. They work by increasing water content within the stratum corneum while reinforcing the lipid matrix that helps retain moisture. Understanding how moisturizers perform can help you determine which are best for your skin. Â
When the barrier is functioning well, skin feels more comfortable, less reactive, and more resilient. Skin protectants are one of the tools available to support that process when reinforcement is needed: They are formulated with FDA-approved active ingredients designed to temporarily protect compromised skin and reduce moisture loss.
Alpha Arbutin helps reduce the look of uneven tone for a brighter looking complexion.

Our new Redness Reform Sulfur Cleanser delivers the clarifying and calming benefits of sulfur in the form of an ultra-plush, gentle formula that leaves skin feeling soothed and hydrated. And it’s clinically proven to perform well on rosacea-prone skin.
Colloidal Sulfur Colloidal sulfur is a potent, nano-sized form of sulfur that is well-studied for its ability to clarify and soothe redness-prone skin. The colloidal sulfur in our Redness Reform cleanser is suspended in a protective Acacia senegal gum colloid, which helps keep the tiny sulfur particles stable and separated—improving absorption, efficacy, and dispersion. (It also has the added benefit of reducing sulfur’s natural odor.) We're always adding more ingredient information - check back later for more on this ingredient.
Our Barrier Therapy Skin Protectant Cream for face and body is part of Prequel's skin protectants collection, a drug category identified by the FDA meant to protect injured or exposed skin from harmful or annoying stimuli while helping to provide relief to the skin. Containing 1% Colloidal Oatmeal, our Barrier Therapy Skin Protectant Cream addresses dryness, eczema flare-ups, and atopic dermatitis.
Hydration is the foundation of a healthy skin barrier. Building on our love of the Multi-Quench Polyglutamic Acid Serum, we wanted to create a mist version to help refresh hydration —and add radiance—throughout the day. The result is a lightweight formula that's as effective as a serum. It’s a new on-the-go essential for keeping skin hydrated, refreshed, and glowy all day long.
Pure PGA + PGA Complex is a multi-molecular weight polyglutamic acid blend that enhances skin moisture retention and helps increase the production of natural moisturizing factors (NMF) for plumper, smoother skin.
Glycerin + Aloe are osmolytes that improve skin hydration, enhance surface elasticity, and soothe.
Niacinamide is a stable form of vitamin B3 that helps smooth skin texture, lock in moisture, and visibly brighten skin tone.
Retinoids are the backbone of any great skincare routine, but they have a reputation for not being something you look forward to applying. That’s why we’re thrilled to introduce Retinal Renew: It’s an advanced retinaldehyde gel that’s powerful enough to deliver the true benefits of retinal, gentle enough to use consistently, and texturally exceptional.
Hydroxysomes Retinaldehyde are a part of the retinoid family closest to retinoic acid on the conversion scale, making it more potent and bioavailable than retinol.
The right skincare routine for dry skin focuses on replenishing hydration, supporting barrier function, and protecting against further water loss. With consistent steps and barrier-focused products, dry skin can feel softer, smoother, and more resilient.
