Hydrating Serum
A serum positioned around polyglutamic acid and niacinamide for moisture, elasticity, and glow, with the official copy also emphasizing calming support.
Best for
Dehydrated or dull-feeling skinGlow-focused serum step
Why it stands out
Moisture-first read
The reliable read is moisture support from polyglutamic acid plus niacinamide glow positioning, not a cure-all emergency treatment.
Routine slot
It fits after toner and before moisturizer, where a lightweight serum can add a hydration layer without replacing barrier cream.
How it fits in a routine

TirTir SOS Serum
The name days it all ! Intense hydrating with PGA which is a humectant 10 x stronger than hyaluronic acid. This power packed serum os the best for dru skin also calms and soothes with the centella asiatica or Cica. I use this 2 x a day after the amazing Toner. After the SOS serum I follow with the incredible Ceramic Milk Ampule then the Ceramic Cream. Perfect system to repair your dry skin or keep your skin in top shape I e for a glass skin affect.
