PHA: Gentle skin renewal, initiating skin regeneration
Nowadays, there are many types of exfoliating acids on the market, such as AHA and BHA. As is well known, these ingredients can make your complexion smoother, brighter, and more firm. However, AHA and BHA can be quite irritating to sensitive skin and can easily cause sensitivity or redness. But don't worry, there is still a type of exfoliating acid on the market that can achieve the same effects as AHA and BHA, but with much milder side effects on the skin. That acid is called PHA.
Advantages of PHA: Gentle and efficient, suitable for all skin types
PHA, also known as polyhydroxy acid, is a chemical exfoliating ingredient whose function is similar to that of AHA and BHA. The main difference between PHA and other chemical exfoliating ingredients (such as AHA and BHA) lies in molecular size. PHA is a larger molecule, which makes it harder to penetrate deep into the skin, causing less irritation. The most common examples of PHA on the market are gluconolactone and lactobionic acid. If you are looking for a milder alternative to AHA and BHA, then these ingredients are very suitable for you. Their benefits include:
Very suitable for sensitive skin
As mentioned above, PHA is very suitable for sensitive skin types because it tends to stay on the surface of the skin and rarely penetrates deep into the skin, thus causing little irritation or allergy.
Exfoliate
As a chemical exfoliating ingredient, PHA removes the epidermis of the skin, mainly dead skin cells. This can reduce hyperpigmentation, increase skin renewal and improve skin texture, making the skin smoother and finer.
3. Moisturizing
PHA is also very helpful for the skin barrier, which can help the skin retain moisture, prevent its loss, and contribute to moisturizing the skin and reducing the appearance of fine lines and wrinkles.
4. Anti-glycation
Glycation is a process in which sugars digested in the body adhere to and bind with collagen in the skin, thereby weakening them. This reduces the collagen in our skin and lowers its elasticity. PHA is rich in antioxidants that can stimulate skin growth and repair, thereby increasing skin elasticity and collagen.
5. Sun protection
Sun exposure and ultraviolet rays can damage our skin cells, increasing the appearance of fine lines and wrinkles. Fortunately, since PHA is a strong antioxidant ingredient, using it can increase skin elasticity, reduce wrinkles and fine lines, making the skin tighter.
