Your overnight mask ritual
Layer it last. Then sleep in it.
Use the GHK-Cu mask as your final night step 1-4 times a week. Apply a thin, even layer after serum, let it settle, then leave it on while you sleep.
Serums first. Mask last.

Leave on
The idea is simple. Apply your serums first, smooth on a thin mask layer, then let the overnight formula do its thing while you sleep.
Apply a thin layer.
Smooth a light layer of the mask over the face and neck. Keep it comfortable, not thick or sticky.
Let it settle.
Give the mask a moment to sit down on the skin before bed so it feels clean, cushiony and comfortable.
Wake and rinse if needed.
Use 1-4 nights per week. In the morning, rinse if you want a fresher feel, then follow with your normal moisturiser and SPF.
Night only Use as a leave-on mask in the evening, 1-4 times per week.
Layering Apply after your serum step and before bed. Keep strong exfoliants separate if your skin prefers a simpler routine.
Texture The blue tint is normal for a copper peptide mask.
Consistency Overnight masks work best when they feel easy enough to repeat.
