Gluconolactone
A gentle exfoliating PHA that helps smooth skin texture while attracting moisture.
What it is: A shake-to-mix PHA toner for balancing surface oil and smoothing uneven texture.
Made for skin that feels dry at the surface but becomes shiny, this shake-to-mix toner brings oil control and gentle exfoliation into one quiet step. Its lightweight, watery texture is especially well suited to excess sebum, visible pores and uneven texture.
The bottle holds two distinct layers. Volcanic ash powder absorbs excess oil and sebum, while the water phase contains 1% PHA to lift away dead skin and help smooth rough texture. Gluconolactone is the key PHA ingredient, and arginine adds moisturizing support to the balancing formula. A thorough shake brings the powder and water together before each use.
Once applied, the toner leaves skin with a smooth, matte finish rather than a sticky layer. Use it with a cotton pad for a light sweep over the face, or press it in gently with your hands. The formula stays on, so there is no need to rinse. It is suitable for all skin types, though its clearest fit is oily skin or skin that feels dehydrated beneath surface shine. It has also passed non-comedogenic and skin irritation testing and is vegan certified.
