AHA (alpha hydroxy acid) and BHA (beta hydroxy acid) are widely used exfoliating ingredients in Korean skincare that help with skin renewal and cleansing. Both acids affect the skin in different ways, but when used together, they can achieve impressive results in skin smoothness, clarity, and freshness.

What are AHA and BHA acids good for?
AHA acids are water-soluble and work on the skin's surface. They are primarily used for exfoliating the skin surface, helping to remove dead skin cells, making the skin smoother and more radiant. They are ideal for dry, dull skin and help fade fine lines as well as even out skin tone.

BHA acids (e.g., salicylic acid) are oil-soluble, so they work deeper inside the pores. BHAs are effective for treating oily and acne-prone skin because they dissolve oil and impurities in the pores, reducing breakouts and blackheads caused by clogging.

The effect of AHA and BHA
Both AHA and BHA acids help skin renewal and achieving a smoother texture. After using AHA acids, the skin becomes fresher, softer, and more radiant, while BHA acids reduce breakouts, cleanse pores, and reduce inflammation. Using them together provides comprehensive skin cleansing that works on both the skin surface and deeper layers.

Benefits of AHA and BHA
Removal of dead skin cells: both acids exfoliate effectively, resulting in cleaner and smoother skin.
Pore cleansing: BHA acids work deep in the pores, reducing clogging and breakouts.
Enhancing skin radiance: AHA acids help the skin look fresher and more vibrant.
Fading fine lines: AHA acids smooth the skin surface, reducing the visibility of fine wrinkles.
The effect of AHA and BHA on the skin
Regular use of products containing AHA/BHA contributes to clearer, more radiant, and more even-textured skin. Exfoliation stimulates skin renewal and helps remove dead skin cells accumulated on the surface, making the skin softer and smoother. However, because AHA/BHA exfoliants can increase light sensitivity, it is recommended to use them in the evening and apply sunscreen during the day.

Therefore, AHA/BHA acids are excellent choices for skin renewal, cleansing, and acne prevention, and they can be used for various skin types in the Korean skincare routine.
