DefenseSerum
A daily protect-and-detox serum for skin carrying the load of modern exposure. Activates the skin's own detox enzymes, neutralizes oxidative stress, supports hydration, and strengthens resilience before the seal.
Defend from the inside out.
Protection from the outside in.
Developed alongside Recovery Cream for skin that is working harder than it should have to. A stressed barrier becomes a sensitive skin: more reactive, more dehydrated, more visible in its distress. Defense Serum addresses that from both directions. It activates the skin's own repair and detox mechanisms while shielding against the environmental exposure that depletes the barrier fastest.
Plant extracts activate the enzymes that clear oxidative buildup and defend against pollution, switching on internal defenses rather than adding another layer on top. A collagen-mimicking peptide drives one of the skin's most powerful antioxidant mechanisms, neutralizing free radicals from pollution, UV, and blue light. A freshwater microalgae extract adds a targeted shield against screen and sun exposure. Four weights of hyaluronic acid rebuild moisture at every depth simultaneously.
Result: with consistent use, skin appears smoother, more resilient, and visibly clearer. Less reactive, better hydrated, and more stable in the face of daily environmental stress.
it fits.
Morning
or evening.
Defense Serum is the protect and detox layer. Apply after hydration and before Recovery Cream. It reduces the stress load before the barrier is sealed.
Apply to damp skin and massage lightly. Rinse with lukewarm water. A barrier-safe cleanse keeps the surface intact before defense.
Apply to damp skin after cleansing. XO Essence calms and prepares the skin before the water layer.
Apply while skin is still damp. Hydrate Serum adds water-binding hydration before the protect and detox layer.
Apply after hydration. Defense Serum activates the skin's own detox enzymes, neutralizes oxidative stress, and reduces the daily exposure load before the barrier is sealed.
Apply after Defense Serum. Recovery Cream repairs the barrier and seals every layer beneath it in place.
Apply every morning as the final daytime step. UV exposure compromises barrier function and increases the daily stress load Defense Serum is built to address.
One of the most important serums in the line. It detoxes and protects in the same pass. Offense and defense, in one step. Antioxidants are quiet work. They do not give you the dramatic before-and-after a TikTok needs. What they do is keep the rest of the routine from undoing itself by Tuesday.
Your skin has detox enzymes. This formula turns them on. Clear from the inside out.
Tips
from the spa.
Born in the spa, Defense Serum reflects practitioner insight: the barrier is not just a boundary, it is a living system that repairs, detoxes, and rebuilds when given the right support. In the treatment room, we use it alongside Recovery Cream for clients whose skin is reactive, sensitized, or recovering from procedure stress. At home, it gives the barrier what it needs to stay stable: daily repair, daily detox, and a shield against the conditions that erode it fastest.

Formulated at Resonance Marin. Tested on real skin. These are the questions that matter most.
The aroma is a quietly elegant, nature-inspired blend replicating the distinct scent of Marin County's coastal air and forests, the environment this formula was made in, and made to support.
Defend the barrier daily.
