The Guardian Mother of All Serums

A DNA-repairing serum is a skin treatment designed to support your skin at its most foundational level—where cellular damage begins. When our skin is exposed to UV rays without protection, it can lead to cellular damage—causing DNA mismatches that interrupt the skin’s natural functions. This means our skin struggles to protect itself, regulate temperature, produce collagen, and stay in balance.

The Guardian was created to support your skin at this foundational level. Using advanced encapsulation technology, this formula delivers DNA-repairing actives deep into the layers where they’re needed most.
Once there, the encapsulation breaks down, releasing the actives to begin the healing process—working in multiple ways to restore cellular function and harmony.

With consistent use, The Guardian helps your skin regain its natural rhythm—strengthening its defenses, enhancing resilience, and encouraging a more radiant, healthy state.

Each of those actives plays a beautiful role in supporting your skin’s health—peptides help
encourage collagen and elasticity, vitamin C brightens and protects, and retinol promotes cell turnover. But The Guardian holds a unique and essential space in your ritual.

While those actives work on the surface or within specific pathways, The Guardian goes deeper—supporting the repair and protection of your skin’s core DNA. Think of it as a holistic healer for your skin. It helps restore
cellular integrity, supports healing from stress and damage, and maintains your skin's natural rhythm and strength.

When your skin’s foundation is healthy and balanced, everything else—collagen production, brightness, renewal—functions more effectively. The Guardian ensures your skin isn’t just treated, but truly cared for at its source.

Absolutely. You don’t need to wait for damage to appear to begin supporting your skin at its core. Using The Guardian daily on healthy skin helps to strengthen the skin barrier, soften the appearance of fine lines, and restore a natural, radiant plumpness—keeping your skin in a state of balance and vitality.

Think of your DNA cells like the core processor of a computer—when that processor is running optimally, everything else functions smoothly. For your skin, this means stronger resilience, better moisture retention, protection against environmental stressors, and reduced signs of fine lines, uneven tone
or congestion.

Even when skin appears “normal,” it’s constantly facing invisible challenges from UV rays, pollution, stress, and time. The Guardian acts as a daily shield and healer, helping your skin defend itself, recover faster, and maintain long-term health—so you continue to glow with strength, clarity,
and grace.

Yes, and in fact, The Guardian was created with sensitivities like yours in mind. Its purpose is to soothe, support, and help your skin heal on a deep, cellular level. For those dealing with rosacea or eczema, The Guardian can calm the burning, tenderness, and itching—while encouraging your skin to repair itself more effectively and comfortably.

That said, healing is always a partnership. While The Guardian nurtures your skin from the outside, it’s just as important to listen to what your body is telling you from the inside. Often, conditions like rosacea and eczema are your body’s inflammatory or allergic responses to internal imbalances or external triggers.

We always encourage tuning into your body—tracking foods, environmental exposures, and emotional stressors can be incredibly helpful in identifying what may be causing flare-ups. The Guardian isn’t a cure-all, but it is a deeply supportive tool to help your skin recover faster and stay resilient as you
uncover the root causes.

With love, patience, and support—both inside and out—your skin can find its way back to balance.

Yes—and it’s one of the skin traumas we’ve studied the most. We’ve done extensive testing on sunburns and minor burns, and the results have been truly remarkable—especially when paired with the Reservoir Prebiotic Mist. Together, this combination instantly cools the skin, reducing heat and the burning sensation almost immediately.

From our testing, The Guardian has been shown to significantly reduce redness within 2 to 4 hours. In many cases, the skin was visibly restored within 14 hours. One of our most meaningful case studies involved an 8-year-old with a first-degree burn on his cheek. He used only The Guardian, morning and night, for 21 days—and the wound healed with almost no visible scarring.

The Guardian is a must-have in my summer skincare ritual. I always bring it on vacation—I apply it to my skin and my children’s before sunscreen, especially before outdoor adventures. Then I reapply it after sun exposure to support healing and recovery. My husband even reaches for it when he gets sunburned or has an acne flare-up—it’s that effective at calming inflammation and helping the skin bounce back faster.

This formula is like a gentle healer—supporting your skin when it needs repair the most.

Absolutely. Fine lines often emerge when DNA damage impairs the skin's ability to produce collagen and elastin—proteins essential for maintaining skin's firmness and elasticity. This degradation leads to the visible creases we recognize as fine lines.

The Guardian's DNA-repairing enzymes work at the cellular level to restore skin function and support the production of these vital proteins.

Clinical studies have demonstrated the efficacy of DNA repair enzymes in reducing fine lines. For instance, a study involving the application of photolyase and other DNA repair enzymes resulted in a significant reduction in crow’s feet lines, with 72% of participants noting improvement . These enzymes help repair UV-induced DNA damage, thereby preserving collagen and elastin integrity.

Furthermore, products containing DNA repair enzymes have been shown to reduce the expression of MMP-1, an enzyme that degrades collagen, by up to 90% . This reduction helps maintain the skin's structural proteins, leading to improved elasticity and a reduction in fine lines.

By incorporating The Guardian into your skincare routine, you're not just addressing the surface appearance of fine lines but supporting your skin's foundational health to prevent and reduce them over time.

The placement of The Guardian can shift depending on what your skin is experiencing.

If your skin is going through a crisis—such as sunburn, irritation, or tenderness—I recommend applying The Guardian immediately after cleansing. This allows it to be the first point of contact, so it can begin calming and supporting your skin’s recovery right away. For added hydration and slip, you can blend it with The Reservoir Prebiotic Mist—together, they create a soothing, restorative layer.

If you’re using The Guardian as part of your daily maintenance ritual, I like to start by resetting my skin’s pH with Yen Heal & Hydrate Essence, then follow with The Guardian, and finish with Sai.

Because the DNA-repairing actives in The Guardian are pH-sensitive, it’s ideal to apply it when your skin is at its natural, slightly acidic state. This environment helps break down the encapsulation that carries the actives, allowing them to reach the layers where repair is needed.

If you're using stronger ascorbic acid products (with a lower pH), I recommend applying them after The Guardian to avoid disrupting that process. However, if you're using our Sai Vitamin C serum, which is formulated with a gentle ester and a skin-friendly pH, you can apply it before or after The Guardian—or even mix the two, depending on your skin’s needs that day.

As always, tune into how your skin feels and responds. Your ritual is a living practice, and your skin will guide you when you listen.
