What does the serum feel like?

It has a watery, lightweight texture that absorbs quickly and layers without pilling when appropriately applied. Using more than recommended may feel sticky or cause pilling.

How should sensitive skin introduce it?

Start with a small amount 2–3 times weekly. Beginner guidance also suggests 1–2 drops every other day before moving toward daily use, while watching how your skin responds.

Can I pair it with vitamin C, retinol, or AHA/BHA?

It can generally be paired with these actives when your skin is comfortable with the routine. When combining several potentially irritating actives, start slowly and reduce frequency or separate them by time of day if stinging or redness occurs.
