The Ordinary Lactic Acid 5% + HA is a water-based facial serum designed to address dullness, fineness, unevenness, and dry skin tone. It contains alpha hydroxy acid (lactic acid 5%) as a primary active ingredient that gently exfoliates dead cells from the surface and helps to provide even complexion and smooth texture. Hyaluronic acid in it helps to hydrate and leave skin feeling calm and comfortable. The Ordinary Lactic Acid 5% is fortified with Tasmanian pepperberry extract, which helps to reduce irritation and sensitivity that is often associated with exfoliation due to acid use. This water-based serum is ideal for dry and sensitive skin. The pH of this formula is approximately 3.8. Lactic acid has a pKa of 3.8, 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, maximising the effectiveness of the acid and reducing irritation. Lactic acid helps in gentle exfoliation of dead cells and provides smoother and healthier-looking skin.
