The Ordinary Glycolic Acid 7% Exfoliating Toner 240ml

• Glycolic Acid 7% Exfoliating Toner (previously Glycolic Acid 7% Toning Solution) is an exfoliator that significantly smoothes skin texture and promotes the appearance of a more even skin tone, as well as more luminous skin, with regular use.
• It also reduces the appearance of lines and wrinkles.
• The water-based toner format is suited to daily use.
• It contains a 7% concentration of Glycolic acid - a well-studied alpha-hydroxy acid - and a plant-derived Tasmanian Pepperberry derivative, which varies in colour seasonally, and which may cause an apparent colour variation in the formula from time to time.
• This formula should not be used on sensitive, peeling or compromised skin.
• Please refer to the additional sun protection notes and other warnings in the provided directions.
• The pH of this formula is approximately 3.6.
• Glycolic Acid has a pKa of 3.6 and pKa is the most important aspect to consider in formulating with acids.
• pKa describes the acidity of a molecule.
• When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing effectiveness of the acid and reducing irritation.
• The multi-functional formula can also be applied to the scalp, where it helps rebalance and reduces dryness by hydrating the scalp skin.
• Made in Canada.
