Lactic acid the ideal ingredient for sensitive skin. The mild exfoliator you need in your skincare routine.
Thanks to our knowledge of the skin barrier – and the factors that damage it – we place great importance on the care products we use, especially on the acids we include in our skincare routine.
And while salicylic acid and glycolic acid work wonders for most of us, their abuse can leave our skin irritated and weaken the skin barrier. Not to mention that they are not always suitable for those with sensitive skin.
So comes lactic acid, the superhero of sensitive skin that removes dead cells and avoids discoloration without irritating.
If you’re thinking of incorporating lactic acid into your skincare, here’s what you need to know.
What is lactic acid
Cleopatra is considered to be the first to “discover” the beneficial properties of lactic acid by enjoying her bath in milk.
Lactic acid belongs to the family of alpha-hydroxy acids (AHA) and is a large and mild molecule, making it ideal for sensitive skin. According to experts, lactic acid binds to the upper level of the skin without penetrating deeply and creates tiles, the oily molecules that play a key role in maintaining maximum hydration in the skin.
What is its action on the skin
When applied to the skin, lactic acid stimulates the exfoliation of cells on the surface of the skin, interfering with their binding. This procedure removes dull, rough skin and boosts the renewal of the skin cells, giving it a youthful and toned skin.
Lactic acid has multiple effects: it increases the tiles on the skin’s protective barrier, increases moisture retention and prevents skin pigmentation.
How often should it be used?
Although lactic acid is one of the mildest acids you can find, you should avoid using it daily. One to two times a week is best for most skin types.
Can it irritate the skin?
As mentioned above, although lactic acid is one of the mildest acids, its abuse or the use of a highly concentrated product can lead to skin irritation. Higher concentrations of acids, although they may be more active, may irritate the skin, causing redness and inflammation.
To choose the right lactic acid product for you, you need to look at both the lactic acid content of the product and the pH levels of the formula. Look for a product with a concentration of 10% or less and pH 3.5-4.0.
Which skin types suit
Lactic acid is ideal for mature, acne-prone and sensitive skin. It is an acid that enhances the appearance of almost every skin, including acne.
What is special about lactic acid?
While glycolic and lactic acid affects the layers of the skin in a similar way, there are some unique additional benefits to the latter.
Lactic acid stimulates collagen synthesis, improves skin texture, wrinkles appearance and reduces discoloration of the skin while fighting over-pigmentation. In addition, lactic acid fits all skin types, which is not the case for many other acids.
