Result: skin looks polished, protected, and ready for the day.

Morning.

Shield SPF 35+ is the final morning Protect step. Apply after serums, cream, or oil, then reapply as directed.

01
Cleanse
Gentle Cleanser
Removes buildup without stripping.

Cleanse first so the morning routine lands on balanced skin. Pat dry or let prior layers settle before SPF.

02
Activate
XO Essence
First layer after cleansing.

Press or mist into skin after cleansing. XO Essence helps hydrate and prepare the surface for the morning layers that follow.

03
Hydrate
Hydrate Serum
Water layer before SPF.

Apply while skin is slightly damp when the routine needs extra hydration and comfort.

04
Treat
C Serum
Morning antioxidant treatment.

Apply before SPF when radiance and tone are the focus. Allow serum layers to absorb before applying Shield SPF 35+.

05
Finish
Protect Oil
Optional lipid finish.

Use a small amount before Shield SPF 35+ when skin is stable and a lipid finish is desired. Let it settle before SPF.

SPF is the one product where my opinion does not matter. Daily, generous, reapplied. The formula’s only job is to make that easy enough that you actually do it.

The Science

The final morning layer matters: mineral SPF protects the routine you built underneath.

01
Zinc Oxide 6% / Mineral SPF Active
Zinc Oxide is one of the mineral sunscreen actives in Shield SPF 35+. It helps provide SPF 35 protection while keeping the formula aligned with sensitive-feeling skin routines.
02
Titanium Dioxide 5% / Mineral SPF Active
Titanium Dioxide works alongside zinc oxide as part of the mineral SPF system. Together, the sunscreen actives support the final morning protection step.
03
Soft-Focus Primer Base
Silicone elastomers and texture-smoothing ingredients help create the refined finish that lets Shield SPF 35+ sit comfortably under makeup or on bare skin.
04
Plant-Derived Emollient Support
Brassica Campestris/Aleurites Fordi Oil supports slip and comfort so the formula applies smoothly and wears with a soft, elegant finish.
From the Treatment Room

Tips
from the spa.

Shield SPF 35+ is the final layer we send clients out with after treatment: mineral protection with a refined finish that looks polished under makeup or on bare skin.

Final Morning Layer
Apply Shield SPF 35+ after serums, cream, or oil have settled. It should be the final skincare step before makeup.
Makeup-Ready Finish
Let Shield SPF 35+ set before foundation or concealer. The soft-focus finish helps create a smoother-looking base without adding another primer step.
Minimal Morning Routine
On streamlined mornings, cleanse, hydrate if needed, then finish with Shield SPF 35+. Reapply as directed throughout the day.
