Surely, everyone has heard about BHA and AHA substances in the skincare routine. So, have you ever wondered what BHA is? What are its functions? How does it affect the skin of the users? Today, let's explore this topic through our article.

What is AHA and BHA? 

 What is BHA?

BHA, or Beta Hydroxy Acid, is an organic acid commonly used in skincare products, particularly in anti-aging and acne treatment products. BHA is typically utilized to exfoliate dead skin cells on the skin's surface, aiding in the removal of the old skin layer and facilitating the regeneration of new cells.

One of the most popular types of BHA is salicylic acid. Salicylic acid is commonly found in acne treatment and oily skin care products due to its ability to penetrate the pores, cleansing oil, sebum, and dead skin cells.

The benefits of BHA (salicylic acid) include:

• Exfoliation: BHA helps eliminate the layer of old skin cells, making the skin appear brighter, smoother, and fresher.
• Cleansing pores: Salicylic acid can deeply penetrate the pores, removing sebum, cleansing dirt, and preventing blemishes.
• Oil control: BHA can absorb oil, helping control oily skin and preventing blackheads.
• Anti-inflammatory and redness reduction: Salicylic acid possesses anti-inflammatory properties, soothing and reducing inflammation on the skin.
• Diminishing wrinkles and dark spots: BHA can help blur dark spots and wrinkles by supporting skin's natural regeneration and improving skin structure.

What is AHA?

Similarly, AHA, or Alpha Hydroxy Acid, is also prevalent in skincare products. AHA works to brighten and smoothen the skin while addressing aging-related concerns.

AHA includes glycolic acid and lactic acid, among others. The benefits of AHA include exfoliating dead skin cells, promoting the regeneration of new cells, brightening the skin, reducing wrinkles and dark spots, and increasing skin elasticity.

In cosmetics, BHA is often used in the form of salicylic acid to treat acne, control oily skin, and reduce inflammation. Some benefits of BHA in cosmetics include exfoliating dead skin cells, cleansing pores, controlling excess oil, reducing inflammation, and treating acne.

When using products containing BHA (salicylic acid), it's essential to follow the instructions and check for any adverse reactions on the skin. For those with sensitive skin, consulting a dermatologist before use is recommended.

Mechanism of Action and Functions of BHA:

BHA primarily acts as an exfoliating agent, helping to shed dead skin cells and promote the regeneration of new cells. BHA works on the outermost layer of the skin, peeling away dead skin cells and facilitating the production of new ones. Additionally, BHA penetrates deep into the pores, addressing issues such as clogged pores and effectively controlling and reducing acne.

Some typical uses of BHA include:

1. Removing dead skin cells and exfoliating: BHA eliminates old skin cells, improving skin brightness and smoothness. Visible improvements can often be observed after 3-6 weeks of use.
2. Diminishing wrinkles and refining skin texture: BHA contributes to reducing the appearance of wrinkles, fine lines, and rough skin texture by promoting cell turnover.
3. Addressing acne and fading dark spots: BHA deeply penetrates pores, removing acne-causing factors, soothing the skin, and effectively reducing dark spots.
4. Controlling excess oil: BHA absorbs excess oil, helping to control oiliness and prevent breakouts.
5. Reducing inflammation: Salicylic acid, a common form of BHA, has anti-inflammatory properties, calming and minimizing inflammation on the skin.

It's crucial to note that everyone's skin type and conditions are different, so the use of BHA should be tailored to individual needs.
