Salicylic Acid 2% Anhydrous Solution
A Water-free serum for gentle exfoliation and pore decongestion.
The Ordinary Salicylic Acid 2% Anhydrous Solution is a water-free product formulated to exfoliate the skin and help decongest pores. Direct acids, specifically alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), are renowned for their ability to support the natural shedding of dead skin. While AHAs aim to promote superficial exfoliation, Salicylic Acid (SA), a lipophilic BHA, is particularly effective at targeting oil within the pores that can lead to congestion. The Ordinary Salicylic Acid 2% Anhydrous Solution offers salicylic acid in a squalane base formulated with the intent of reducing concerns of skin irritation that can be associated with the use of SA.
This formula is a water-free product formulated to effectively decongest the skin, and impart a superficial exfoliating effect. This will result in a visible reduction of textural irregularities, with improved skin tone homogeneity and clarity over time.
The Ordinary Salicylic Acid 2% Anhydrous solution offers fully solubilized (not suspended) SA, in an emollient, squalane-based vehicle, that is formulated with the intent of reducing concerns of skin irritation that can be associated with the use of SA.
Hydrous SA formulations rely on the formula’s pH for a delivery of the active, with an acidic pH increasing the availability of SA in its active form. This is because SA in aqueous solutions exists in two forms: active (free acid) form and ionized form. At a pH of 2.97 (corresponding to SA’s pKa value), half of the SA in solution will be ionised, and half will be in the active (free acid) form. Increasing the pH of the formulation will decrease the level of free acid, possibly impacting product efficacy. The anhydrous nature of this formula allows for the release of free-form, unionized acid, independent of pH.
This formulation is further supported by hydrating polyglycerides derived from sunflower oil, acting as lipophilic film-formers, which aim to slow the ingredient’s delivery to the skin, for controlled skin availability. Additionally, 4-t-butylcyclohexanol was included to help address signs of sensitivity or discomfort.

Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product. Apply a small amount of the product onto a clean area of skin on the upper forearm. Keep the area dry. If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours. If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
