5. Stimulates collagen production
“Additionally, lactic acid can stimulate the production of collagen and structural molecules called glycosaminoglycans (GAGS), resulting in firmer, plumper skin with fewer fine lines and wrinkles,” he says.
6. Fades signs of discoloration
Dark spots and spots of uneven skin tone are the result of excessive pigment production by your skin cells. Triggers include sun exposure, hormonal changes, inflammation and acne scarring. According to Paula Begoun, founder of Paula’s Choice, concentrations of 5 to 12 percent lactic acid help fade signs of discoloration by accelerating the shedding and turnover of these cells on the skin’s surface.
Can you use lactic acid every day?
“Lactic acid can be used daily; however, if you experience dryness, redness or irritation, you will need to use smaller amounts or use it less frequently,” says consultant dermatologist Magnus Lynch.
Also note the other ingredients you apply to your skin and “avoid using multiple exfoliating acids.” [such as salicylic acid and glycolic acid] in the same routine as lactic acid, unless they have been formulated to work together,” says Dr. Phillips.
What is the best way to use lactic acid for skin?
Available in the form of cleansers, exfoliants, serums and creams, lactic acid can easily be incorporated into your daily skincare routine. For beginners, look for a product with a low concentration (5% to 10%) and work your way up slowly. Start by using it one to three times a week to build tolerance, and increase the frequency only if there is no redness or irritation.
Most importantly, “be sure to use sunscreen during the day, as lactic acid can make your skin more sensitive to the sun,” says Dr. Lynch.
As a cleanser: “I would recommend starting with a cleanser that contains lactic acid and using it at night,” says Dr. Lynch. “Then follow with a nourishing moisturizer. »
As an exfoliant: A lactic acid exfoliant comes in the form of a peel, scrub, or toner, so it’s important to follow the directions on each individual product. Some toners and treatments are gentle enough to use daily; others with a higher percentage of lactic acid should generally be applied to clean, dry skin with a cotton pad several times a week, always avoiding the eye area.
