Calm Barrier Serum
€34
The serum that got my skin barrier back after a retinol mishap. No sting on compromised skin, a soft, slightly bouncy finish, and redness that settles within a fortnight.
- Best for
- Combination, sensitive
- Key actives
- Niacinamide 5%, ceramides
- Fragrance
- None
- Cruelty-free
- Yes
How I use it
Two drops, morning and evening, on damp skin after cleansing and before moisturiser. It layers under everything I own. In the first week I used four drops and it pilled under SPF, so less really is more.
The honest bit
Loved
- No sting on compromised skin
- Sinks in under 30 seconds
- One bottle lasts about four months
Not so much
- Dropper is fiddly near the end
- Pricey outside sale weeks
Who it's for
Anyone with redness, tightness or a barrier that's been over-exfoliated. Oily skin may want something lighter in summer. If the price is the dealbreaker, the Halden niacinamide drops do 80% of the job for half the cost.
