FAQ Kiehl's - ULTRA PURE high-potency serum 9,8% glycolic acid

?
What benefits does Kiehl's Ultra Pure Glycolic Acid offer?
Translated by Google
-25-03-2026
It is the intensive rejuvenating treatment that guarantees:
• Visibly brighter and more radiant skin.
• Dramatic improvement in the texture and smoothness of the face.
• Reduction of surface imperfections.
?
Should Ultra Pure Glycolic Acid be used during the day or at night?
Translated by Google
-18-02-2026
It is recommended to use it preferably at night. It is essential to apply a broad-spectrum sunscreen the following morning, as glycolic acid increases sensitivity to the sun.
?
Is it normal to feel a slight tingling sensation with this Kiehl's serum?
Translated by Google
-02-01-2026
Yes, due to its 9.8% glycolic acid concentration, it is common to experience a sensation of activity on the skin during the first few seconds after application.
?
How does the Ultra Pure High-Potency Serum with glycolic acid work?
Translated by Google
-14-11-2025
This high-potency concentrate helps gently exfoliate the skin's surface to accelerate cell renewal, resulting in a much smoother texture and minimizing the appearance of pores.
