My cheeks are less red
Rosacea-prone, and this is the first serum that calmed things rather than set them off. Took about three weeks.

Shine under control by 3pm
I used to blot twice a day. Now my nose and forehead stay matte until mid-afternoon.

Fewer breakouts, some pilling
Breakouts are down, but it balls up under my moisturiser most mornings. I now use it only at night.
Reply from Cuvette · Marta, formulation
Thanks, Maximilian. The xanthan gum that gives it slip can pill under thicker creams if they go on while it's still wet. Give it a full minute, or use a lighter gel moisturiser on top. Nights only is a good routine too.
Next in your morning
Hyaluronic 2%
Holds water in the skin all day. Morning and night, on damp skin.
Morning step 3, after Vitamin C. Night step 2, before Niacinamide or moisturiser.
