What is AHA and BHA? : Skincare Acids Decoded

Skincare acids have become increasingly popular in recent years, particularly AHA and BHA acids. These acids are commonly used in skincare routines to improve skin texture, reduce acne and fine lines, and even out skin tone. But with so many different types of acids available, it can be challenging to know which one is right for you. In this blog, we will decode the difference between AHA and BHA, explain their benefits and how to incorporate them into your skincare routine and provide recommendations for products to try.

What is AHA?

AHA, or alpha hydroxy acid, is a group of water-soluble acids derived from fruits and milk. AHAs work by breaking down the bonds between dead skin cells on the surface of the skin, allowing them to be easily sloughed off and revealing smoother, brighter, and more even-toned skin underneath. Some common types of AHAs include glycolic acid, lactic acid, and mandelic acid.

One of the primary benefits of AHA is exfoliation. By removing dead skin cells, AHA can help to unclog pores, reduce the appearance of fine lines and wrinkles, and improve overall skin texture. AHA can also help to reduce hyperpigmentation by breaking down the melanin that causes dark spots.

AHA is suitable for most skin types, particularly those with dry, rough, or dull skin. However, people with sensitive skin may experience irritation or redness when using AHA, so it's important to patch test before incorporating it into your skincare routine. AHA is also not recommended for use on broken or inflamed skin.

What is BHA?

BHA, or beta-hydroxy acid, is another type of skincare acid commonly used in skincare products. Unlike AHA, BHA is oil-soluble, meaning it can penetrate through oil and get deep into the pores of the skin. This makes it a popular choice for those with acne-prone or oily skin.

The most common type of BHA is salicylic acid, which has anti-inflammatory and anti-bacterial properties. It works by exfoliating the skin and unclogging pores, which can help prevent breakouts and reduce the appearance of blackheads and whiteheads.

BHA is also effective in reducing the appearance of fine lines and wrinkles, as well as improving the overall texture and tone of the skin. It is a gentle exfoliant that can be used daily without causing irritation.

However, as with AHA, BHA is not suitable for everyone. Those with sensitive or dry skin may find BHA too harsh and irritating and should opt for a gentler exfoliant. Additionally, pregnant or breastfeeding women should avoid using BHA products, as it can be absorbed into the bloodstream and potentially harm the baby.

AHA vs. BHA: Which skincare product is right for you?

AHA and BHA are both skincare acids that work to exfoliate the skin and improve its texture, but they differ in their molecular structure and uses.

As already discussed, AHA, or alpha-hydroxy acid, is a water-soluble acid that works on the surface of the skin to exfoliate dead skin cells and improve skin texture. Common types of AHA include glycolic acid, lactic acid, and mandelic acid. AHA is ideal for people with dry or sun-damaged skin, as it can help to reduce the appearance of fine lines and hyperpigmentation.

On the other hand, BHA, or beta-hydroxy acid, is an oil-soluble acid that can penetrate deeper into the skin to unclog pores and reduce acne. The most common type of BHA is salicylic acid. BHA is ideal for people with oily or acne-prone skin, as it can help to reduce breakouts and control excess oil production.

When it comes to choosing between AHA and BHA, it's important to consider your skin type and concerns. If you have dry or sun-damaged skin and are looking to improve texture and reduce hyperpigmentation, AHA may be the better option for you. On the other hand, if you have oily or acne-prone skin and are looking to reduce breakouts and control oil production, BHA may be the more suitable acid for your skin. It's also worth noting that some people may benefit from using both AHA and BHA in their skincare routine, depending on their individual skin concerns.

How to Use AHA and BHA the right way?

When incorporating AHA and BHA into a skincare routine, it's important to start slowly and gradually increase frequency to allow the skin to adjust. It's recommended to use AHA and BHA products once or twice a week initially, then increase to every other day or daily as tolerated.

To use AHA and BHA safely and effectively, it's important to follow the instructions on the product label and use them as directed. Generally, AHA products are applied as a toner or serum after cleansing, while BHA products can be applied as a spot treatment or all-over treatment. It's important to avoid using AHA and BHA products in combination with other exfoliants, as this can cause irritation and over-exfoliation.

Potential side effects of AHA and BHA include dryness, redness, and flakiness. To minimize these side effects, it's important to use a moisturizer and sunscreen daily and avoid over-exfoliating the skin. It's also recommended to patch test new AHA and BHA products on a small area of skin before using them all over the face. If any irritation or adverse reactions occur, discontinue use and consult a dermatologist.

Choosing the Right AHA or BHA for your skin

Choosing the right AHA or BHA product can be overwhelming, as there are many options on the market. However, there are a few factors to consider that can help narrow down the choices and ensure you are selecting the right product for your skin type and concerns.

  1. Skin type: Different AHAs and BHAs are better suited for different skin types. For example, those with dry or sensitive skin may benefit more from lactic acid, while those with oily or acne-prone skin may find salicylic acid more effective.

  2. Specific concerns: Consider what specific skin concerns you are looking to address, such as fine lines and wrinkles, hyperpigmentation, or acne. Different AHAs and BHAs may be more effective at treating certain concerns.

  3. Product strength: AHAs and BHAs come in varying strengths, typically ranging from 5% to 30%. If you are new to using acids, it's best to start with a lower strength and gradually increase as your skin becomes accustomed to the product.

  4. pH level: The pH level of the product is also important to consider. AHAs work best at a pH level of 3-4, while BHAs work best at a pH level of 3-4.5. Look for products with the correct pH range for optimal results.

  5. Product formulation: AHAs and BHAs come in different formulations, such as toners, serums, and creams. Choose a product formulation that works well with your existing skincare routine and is easy to incorporate.

When reading product labels, be sure to check the percentage of AHA or BHA in the product, as well as the pH level and other key ingredients. This can help you determine if the product is suitable for your skin type and concerns.

Wrapping Up

AHA and BHA acids can be powerful tools in a skincare routine, but it is important to choose the right acid and use it properly to avoid any negative effects. AHA is best for exfoliating the surface of the skin and improving texture and hyperpigmentation, while BHA is better suited for those with acne-prone or oily skin. When incorporating acids into your skincare routine, start with a low concentration and gradually increase the frequency of use. It is also important to wear sunscreen daily to protect the skin from UV damage. Remember to choose a product that is appropriate for your skin type and specific concerns, and always follow the instructions on the label. With proper use, AHA and BHA can help improve the overall appearance and health of your skin.
