How it works

It is a thin fluid rather than a gel, so a few drops cover the face and settle without a film. Pressed on damp skin it sinks in quickly and leaves the surface ready for a cream. It is doing a narrower job than an all-purpose lotion, and that is the reason it goes on before one. It goes on after your watery step and before the cream that seals everything down. The honest measure is the way the skin looks in the mirror once everything has settled.

Key benefits

  • Niacinamide sits at position #6 of 33 on A-CICA 365 Soothing Relief Serum pH4.5's own manufacturer ingredient list.
  • Squalane is also named on that same list, further down the formula.
  • A-CICA 365 Soothing Relief Serum pH4.5 is a serum from AESTURA, taking the serum's usual place in a layered Korean routine.
  • AESTURA ships A-CICA 365 Soothing Relief Serum pH4.5 here as the Korean-market formula, the same version sold on shelves in Korea, not a US-shelf reformulation.
  • Sold with intact Korean-market barcode and batch coding rather than a US-retail relabel.

How to use

  1. Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
  2. Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
  3. Follow with a moisturizer within a minute so the thin layer has something holding it down.
  4. Do not stack it under a second serum doing the same job, since more layers is not the same as more result.

Worth knowing

  • Patch test on a small area of the jaw first if your skin reacts easily to something new.
  • Stop for a few days if the skin starts to sting, then bring it back on alternate evenings.
