What Are AHA and BHA Chemical Exfoliants?
Chemical exfoliants are a popular choice for those looking to improve the texture and appearance of their skin. Unlike physical exfoliants, which use abrasive particles to remove dead skin cells, chemical exfoliants rely on acids to dissolve the bonds between cells.
There are two main types of chemical exfoliants: beta-hydroxy acids (BHAs) and alpha-hydroxy acids (AHAs).
BHAs, such as salicylic acid, are oil-soluble and penetrate deep into the pores to unclog them. Meanwhile, AHAs, such as glycolic and lactic acid, are water-soluble and work on the surface of the skin to gently remove dead skin cells.
About Paula's Choice BHA
BHAs are particularly effective for those with oily or acne-prone skin. They are able to penetrate deep into the pores to unclog them, which can help to reduce the appearance of blackheads and whiteheads.
BHAs also have anti-inflammatory properties, which can help to reduce redness and irritation associated with acne.
In addition to their acne-fighting properties, BHAs can also help to improve the overall texture and tone of the skin. They are able to exfoliate the skin without causing irritation, making them a great choice for those with sensitive skin.
About The Ordinary AHA BHA
AHAs and BHAs are often used together in skincare products to provide a more comprehensive exfoliating experience.
AHAs work on the surface of the skin to gently remove dead skin cells, while BHAs penetrate deep into the pores to unclog them.
Together, these acids can help to improve the texture and tone of the skin, reduce the appearance of fine lines and wrinkles, and even out skin tone. They can also help to reduce the appearance of pores and improve the overall clarity of the skin.
When choosing between Paula's Choice BHA and The Ordinary AHA/BHA, it's important to consider your skin type and concerns. BHAs are a great choice for those with oily or acne-prone skin. However, AHAs are better suited for those with dry or sensitive skin.
Ultimately, both types of acids can provide significant benefits for the skin when used correctly.
Paula's Choice BHA Vs The Ordinary AHA BHA - Ingredients Comparison
Paula's Choice BHA and The Ordinary AHA/BHA are two popular skincare products that are used to exfoliate the skin. Both products contain beta-hydroxy acids (BHAs) and alpha-hydroxy acids (AHAs) that help to remove dead skin cells and unclog pores. However, there are some differences in the formulation of these two products.
Paula's Choice BHA contains salicylic acid, which is a type of BHA that is oil-soluble and can penetrate deep into the pores. This makes it effective for treating acne and blackheads.
On the other hand, The Ordinary AHA/BHA contains glycolic acid, lactic acid, and salicylic acid. Glycolic acid and lactic acid are types of AHAs that are water-soluble and work on the surface of the skin to exfoliate it.
Paula's Choice BHA Vs The Ordinary AHA BHA - Efficacy
Both Paula's Choice BHA and The Ordinary AHA/BHA are effective in exfoliating the skin and improving its texture. However, the choice between these two products depends on the skin concern that needs to be addressed.
Paula's Choice BHA is more effective for treating acne and blackheads due to its ability to penetrate deep into the pores. It also helps to reduce inflammation and redness associated with acne.
On the other hand, The Ordinary AHA/BHA is more effective for treating hyperpigmentation, fine lines, and wrinkles due to the presence of AHAs that work on the surface of the skin.
Skin Types Suitability
Both Paula's Choice BHA and The Ordinary AHA/BHA are suitable for all skin types. However, it is important to note that salicylic acid can be drying for some people, especially those with dry or sensitive skin.
In such cases, it is recommended to use a lower concentration of salicylic acid or opt for The Ordinary AHA/BHA, which contains AHAs that are gentler on the skin.
Price Comparison
Paula's Choice BHA is more expensive than The Ordinary AHA/BHA. This is because Paula's Choice uses high-quality ingredients and has a reputation for producing effective skincare products.
However, The Ordinary AHA/BHA is a more affordable option for those who are on a budget. It is important to note that the price difference between these two products may vary depending on the size of the bottle and the retailer.
Side Effects and Precautions
Side Effects of BHA
BHA, or beta hydroxy acid, is a common ingredient in many skincare products, including Paula's Choice BHA. While generally safe for most people, there are some potential side effects to be aware of.
One of the most common side effects of BHA is dryness or irritation, especially for those with sensitive skin. To minimize this risk, it is important to start with a low concentration and gradually increase over time.
Another potential side effect is increased sun sensitivity. This is because BHA can exfoliate the top layer of skin, leaving it more vulnerable to UV damage.
It is important to always wear sunscreen when using BHA products.
Side Effects of AHA/BHA
The Ordinary AHA BHA also contains both alpha and beta hydroxy acids, which can have some potential side effects.
Like BHA, AHAs can cause dryness and irritation, especially for those with sensitive skin. It is important to start with a low concentration and gradually increase over time to minimize this risk.
Another potential side effect of AHAs is increased sun sensitivity, as they can also exfoliate the top layer of skin.
In addition, AHAs can increase the risk of skin damage if not used correctly. It is important to follow the instructions carefully and avoid over-exfoliating, which can lead to redness, flaking, and other skin issues.
