The Ordinary Glycolic Acid 7% Toning Solution is an exfoliating toner which brightens, tones & helps improve skin texture. 

Glycolic Acid 7% Toning Solution is an alpha hydroxyl acid serum that exfoliates the skin. Glycolic Acid is an alpha hydroxyl acid that exfoliates the skin. This 7% tonic solution offers mild exfoliation for improved skin radiance, glow and visible clarity. The formula also improves the appearance of skin texture with continued use.

The formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time. The formula is further supported with inclusion of ginseng root and aloe vera for both visible radiance and soothing benefits.

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 implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing effectiveness of the acid and reducing irritation. Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic.

Note: While exfoliating acids can result in quick visible benefits, Deciem generally suggest indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids. Please refer to NIOD's Non-Acid Acid Precursor for such a reference.
