In the ever-evolving world of skincare, two acronyms have become increasingly popular: AHAs and BHAs. These chemical exfoliants have revolutionized the way we care for our skin, offering powerful benefits that go beyond traditional physical scrubs.
But what exactly are they, and how do they differ?
This blog post will dive deep into the world of hydroxy acids, exploring their unique properties, benefits, and how to choose the right one for your skin type.
What are AHAs and BHAs?
Alpha Hydroxy Acids and Beta Hydroxy Acids are both types of chemical exfoliants that work to remove dead skin cells and improve skin texture. However, their molecular structure and properties differ significantly.
| PROPERTY | AHAs | BHAs |
| Water Solubility | Water-soluble | Oil-soluble |
| Penetration | Surface level | Deeper into pores |
| Primary Function | Exfoliation and hydration | Exfoliation and oil control |
How do AHAs Work?
These water-soluble acids are derived from various sources, including fruits, milk, and sugarcane. They work primarily on the skin’s surface, loosening the bonds between dead skin cells and promoting cell turnover.
Here are the key benefits:
- Improve skin texture and tone
- Reduce the appearance of fine lines and wrinkles
- Enhance skin hydration
- Boost collagen production
- Even out skin pigmentation
Popular AHAs include:
- Glycolic acid
- Lactic acid
- Mandelic acid
- Citric acid
The Power of BHAs
BHAs, on the other hand, are oil-soluble acids that can penetrate deeper into the pores. They are often the go-to choice for those with oily, acne-prone skin due to their ability to dive deep into the pores and clear out excess sebum and debris.
Due to its oil-soluble nature, they are particularly effective for:
- Unclogging pores
- Reducing acne and blackheads
- Controlling excess oil production
- Calming inflammation
- Exfoliating the skin surface
Popular BHAs:
- Salicylic acid (link blog)
- Tropic acid
- Trethocanic acid
Choosing Between Them
Selecting the right hydroxy acid for your skin depends on your specific skin concerns and type. Here’s a quick guide to help you choose:
Choose AHAs if you have:
- Dry or sun-damaged skin
- Concerns about fine lines and wrinkles
- Uneven skin tone or hyperpigmentation
Choose BHAs if you have:
- Oily or acne-prone skin
- Blackheads or whiteheads
- Large or congested pores
For those with combination skin or multiple concerns, using both can be beneficial. You can alternate between the two or use products that combine both acids in lower concentrations.
It is highly recommended that you consult a trusted dermatologist before incorporating these exfoliating agents into your skincare routine.

FAQs
Q: Can I use them together?
A: Yes, you can use both in your skincare routine. However, it’s best to alternate their use or choose products that combine both in lower concentrations to avoid over-exfoliation.
Q: How often should I use them?
A: Start with 1-2 times a week and gradually increase frequency as your skin tolerates it. Some people can use them daily, while others may need to limit use to 2-3 times a week.
Q: Do I need to wear sunscreen when using them?
A: Yes, both can increase skin sensitivity to the sun. Always use a broad-spectrum sunscreen with at least SPF 30 when using these exfoliants.
Q: Do they have different pH levels?
A: Yes, AHAs typically work best at pH 3-4, while BHAs are effective at slightly higher pH levels, around 3-4.5.
Q: Are there any side effects of using them?
A: Some people may experience temporary redness, dryness, or peeling when first using these acids. If irritation persists, reduce the frequency of use or consult a dermatologist.
