AHAs vs. BHAs: Which Exfoliant Is Right for You?
Discover the key differences between AHAs and BHAs and why First Lady London AHA products are the perfect choice for brightening your skin.

When it comes to achieving radiant, healthy-looking skin, exfoliation is non-negotiable. Exfoliants help slough away dead skin cells, unclog pores, and promote a brighter complexion. Two of the most popular types of chemical exfoliants are AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids). But which one is best for your skin? This detailed guide compares AHAs vs BHAs exfoliants, backed by scientific insights and dermatological advice, to help you choose the best option. Plus, we spotlight why First Lady London’s AHA products are your ultimate brightening solution.
Understanding the Basics: What Are AHAs and BHAs?
AHAs (Alpha Hydroxy Acids) are water-soluble acids derived from fruits and milk. They primarily work on the skin’s surface, loosening the bonds between dead skin cells and promoting their natural shedding. Common types of AHAs include glycolic acid, lactic acid, mandelic acid, and citric acid.
According to the NHS, regular exfoliation with gentle acids like AHAs can improve skin tone and texture (source).
On the other hand, BHAs (Beta Hydroxy Acids) are oil-soluble. They penetrate deeper into the pores to clear out excess sebum and debris. Salicylic acid is the most well-known BHA.
The British Association of Dermatologists notes that BHAs are particularly effective for oily, acne-prone skin (source).

How to Choose: Which One Is Right for Your Skin?
Choose AHAS if:
- You have dry, rough, or sensitive skin.
- You want to fade dark spots, pigmentation, or sun damage.
- Your goal is to achieve a radiant, more even complexion.
- You are concerned about fine lines and early signs of ageing.
AHAS, like glycolic and lactic acid, stimulate collagen production and cell turnover, which are crucial for brightening and rejuvenating the skin (British Skin Foundation).
Choose BHAS if:
- You have oily or acne-prone skin.
- You struggle with blackheads and enlarged pores.
- You need an anti-inflammatory solution to manage breakouts.
Salicylic acid, a BHA, works deep inside the pores to dissolve sebum and combat acne-causing bacteria, making it perfect for congested skin types.

Science-Backed Reasons to Choose AHAs
Recent studies published by the British Journal of Dermatology show that glycolic acid, a primary AHA, significantly improves photoaged skin and boosts collagen synthesis (source).
Moreover, AHAs enhance the absorption of moisturisers and serums by creating a smoother, more receptive skin surface. This means that by using First Lady AHA products, you’re exfoliating and maximising the benefits of your entire skincare routine.
How to Incorporate AHA Exfoliants into Your Routine
Transitioning to AHA exfoliants is transformative yet straightforward:
- Start Slowly: Begin with every other use to allow your skin to adjust.
- Apply at Night: AHAs can increase sun sensitivity; therefore, night-time application is recommended.
- Use Sunscreen: Always protect your newly exfoliated skin with a broad-spectrum SPF during the day.
- Moisturise Well: Follow with a hydrating product to lock in moisture.
First Lady London’s Fast Active AHA range is formulated to be gentle yet highly effective, making it suitable even for sensitive skin types when used as directed.
Common Myths About AHAs and BHAs
Myth 1: Exfoliating daily is better.
Truth: Over-exfoliation can damage the skin barrier. For optimal results, experts from the NHS recommend exfoliating 2-3 times per week.
Myth 2: AHAs and BHAs are only for acne.
Truth: While BHAs target acne, AHAs are powerful anti-ageing and brightening agents.
Myth 3: Natural exfoliants are always safer.
Truth: When formulated correctly, chemical exfoliants like AHAs and BHAs are often gentler and more consistent than physical scrubs.

In the battle of AHAs vs. BHAs exfoliants, the winner depends on your skin’s unique needs. If your goal is to:
- Brighten dull skin,
