The Shield

The single most important step — finally one you will not skip.

A mineral SPF 40 that behaves like skincare: no white cast, no chalk, no heaviness. A soft, tinted-neutral fluid that protects against UV and blue light while smoothing tone, and sits beautifully under makeup or entirely alone. Non-negotiable the morning after any retinal night — it is the other half of how the protocol works.
