TIRTIR SOS Serum is a 50ml soothing, hydrating serum built around polyglutamic acid (PGA), a moisture-binding ingredient the brand compares to hyaluronic acid, suited to dehydrated or stressed-feeling skin that needs calming.

What it does

The SOS Serum is TIRTIR's rescue step for skin that feels dry, tight or reactive. Its key ingredient is polyglutamic acid, which the brand states holds more water than hyaluronic acid, helping skin hold onto moisture through the day. The texture is a light, slightly viscous gel that spreads easily and absorbs without tackiness. Skin feels soothed and comfortable, and looks plumper, dewier and more rested. It layers well under moisturiser or SPF and can be used as a quick hydration boost whenever skin feels out of sorts.

How to use

Morning and evening after toner, press two to three drops over the face and neck and pat until absorbed. Follow with moisturiser. Can be applied more generously at night as a hydrating layer. Patch-test first.

Who it's for

Dehydrated, sensitive or easily stressed skin, and anyone who wants a gentle, non-sticky hydrating serum with a calming feel for daily use.
