Description

This is a 30ml liquid serum exfoliator formulated with 10% lactic acid, an alpha hydroxy acid (AHA), to work on the skin's surface. The formula also contains sodium hyaluronate crosspolymer and Tasmannia lanceolata fruit extract. Lactic acid is a chemical exfoliant that works on the skin's surface; sodium hyaluronate crosspolymer is a humectant that attracts water to the skin.

Per the brand, this is a high-strength exfoliator suited to dry skin and targets dullness, textural irregularities and uneven skin tone. The brand describes it as water-based and formulated without fragrance, oil, alcohol, silicone, nuts or gluten. Per the brand, it is vegan and cruelty-free. It comes with a dropper applicator for controlled application.

Because it contains an AHA, the brand notes it may increase your skin's sensitivity to the sun and recommends using broad-spectrum sunscreen and limiting sun exposure during use and for a week after. The brand advises performing a patch test before incorporating this product into your routine and cautions against combining it in the same routine with direct acids, retinoids, pure or ethylated vitamin C, EUK 134 0.1%, or peptides.
