Exfoliation
All about EXFOLIATION!
AHA is a water-soluble acid often extracted from sugar cane, fruit, and milk, and contains components such as glycolic acid, lactic acid, citric acid, malic acid, mandelic acid, and tartaric acid, which are the most commonly used exfoliating ingredients.
It has a clear exfoliating effect that causes dead keratinocytes to fall off the outermost layer of the skin.
Since it is an ingredient that can be accompanied by high stimulation, caution should be exercised when using high concentration products for a long time.
It is not certain that AHA has a positive exfoliating effect simply because it has a high content.
*High concentrations of AHA may cause serious skin irritation or side effects.
If you haven't used AHA yet, or if you have sensitive skin, it's good to start with a product with low concentrations of AHA.
If you are familiar with AHA, it might be a new way to try a product with a slightly higher concentration and proper pH balance.
Salicylic acid extracted by refining salicin in willow bark is a representative BHA component.
Like AHA, it has the effect of removing dead keratinocytes in the outermost layer of skin and removing sebum and waste products in the pores due to its oil-friendly properties.
Salicylic acid is very toxic when used in high concentrations and can cause serious side effects, so using large amounts is strictly prohibited.
Betaine salicylate, which synthesizes betaine into salicylic acid, is another BHA that is also known to reduce the stimulation of salicylic acid and have similar effects to salicylic acid.
If you are looking for an exfoliant that removes sebum from pores, using BHA products is a good choice.
PHA is an exfoliating component that follows AHA and BHA, and is known to cause less irritation than AHA and BHA, while having an exfoliating effect like them. Gluconolactone and lactobionic acid are the most popular PHAs.
Using exfoliating ingredients with AHA or BHA can temporarily cause dry skin depending on skin type, but PHA is a relatively moisturizing and exfoliating ingredient because it exfoliates while also moisturizing the skin.
It also has a function to alleviate environmental damage and irritants such as ultraviolet rays, so it is good for those who are concerned about sensitive skin after exfoliation.
Capryloylsalicylic acid, a derivative form of salicylic acid (BHA), is a representative LHA.
It is known to penetrate the skin relatively slowly and to be very mild because it has a high molecular weight compared to other chemical exfoliating ingredients.
With its mild exfoliating effect, it is easy to use ingredients with anti-aging effects for all skin types, including sensitive skin.
If you want to exfoliate and improve your skin at the same time, you can start with an LHA product.
Let's take good care of your skin by using the right skin care products with the right ingredients for your skin!
