Propylene glycol

Propylene glycol gently calms flaking skin and eases dryness, while remaining very gentle on healthy skin. It suits both dry skin and oily skin well, appearing most often in lightweight serums. Because it layers easily, it fits simply and smoothly into your daily routine.

Questions and answers

What does propylene glycol do for the skin?

Propylene glycol helps improve skin hydration and acts as a delivery agent for other active ingredients in topical treatments. When combined with urea and lactic acid in products like K301, it may significantly reduce scalp flaking and related symptoms over four weeks.

Should you use propylene glycol in the morning or at night?

Propylene glycol may be used both morning and night, as it has a low risk for skin irritation on healthy skin. It is often included in various daily topical treatments to help improve skin conditions.

Can you use propylene glycol every day?

Propylene glycol is unlikely to cause irritation when used daily on healthy skin because it has a very low sensitization potential.

Does propylene glycol cause purging or irritation?

Propylene glycol is unlikely to cause irritation on uncompromised skin as it exhibits very low sensitization and irritation potential. It does not cause purging, as purging only occurs with active ingredients that accelerate skin cell turnover.

Which skin types is propylene glycol best for?

Propylene glycol helps various skin types, achieving top fits with products like Kiehl's Calendula Herbal-Extract Toner and Mario Badescu Facial Spray with Aloe, Chamomile and Lavender. Lovi rates Kiehl's Calendula Herbal-Extract Toner as a Superior fit for oily, sensitive, acne-prone, oily acne-prone skin, and skin with dark spots, while giving Mario Badescu Facial Spray a High fit across multiple skin types.
