Have you heard of AHAs? And if the word “acid” instantly made you think of something harsh or unpleasant, don’t worry – that’s far from the case here. In fact, AHAs (Alpha Hydroxy Acids) are a bit of a skincare magic trick, known for revealing brighter, fresher-looking skin. Did you know they can noticeably improve the appearance of your skin in just a few weeks of use?
In this article, we’ll uncover how AHAs work, the different types available, and how you can introduce them into your daily routine.
What are AHAs and how do they work?
AHAs, or Alpha Hydroxy Acids, are a group of naturally occurring acids typically derived from fruit and dairy. Some of the most common ones include glycolic, lactic and citric acids – all widely used in skincare. AHAs are natural exfoliants that help renew the skin, giving it a smoother, more radiant appearance.
Their mechanism is simple yet powerful: AHAs work by loosening the bonds between dead skin cells on the surface, encouraging the skin’s natural cell renewal process. This helps slough off dull skin, leaving a smoother and more even texture behind.
AHAs are highly effective at targeting issues like hyperpigmentation, early signs of ageing, and uneven texture. They even out skin tone, soften fine lines, restore radiance, and help prevent clogged pores and breakouts.
Tip: For enhanced results, try pairing them with the Skin Perfection Azelaic Serum, which works in synergy with AHAs to calm inflammation, even skin tone, and reduce blemishes.

Types of AHAs and their benefits
Although all AHAs belong to the same group, they differ in molecular size – which affects how deeply they penetrate the skin and which skin types they suit best. Here’s a closer look at the most common ones:
- Glycolic acid – The smallest molecule, making it deeply penetrating and ideal for decongesting pores and refining skin texture. Best suited for oily skin, or skin showing signs of premature ageing.
- Lactic acid – A gentler option, making it great for dry or sensitive skin. It supports hydration and helps repair the skin’s barrier while also improving elasticity.
- Citric acid – A great choice for brightening the complexion and reducing uneven pigmentation. It refreshes dull skin and helps diminish the appearance of dark spots.
→ Note: Always match the concentration of acids to your skin type. For at-home use, lower concentrations (5–10%) are typically best, while stronger formulations are used in professional treatments for more intensive results.
How to safely use AHAs in your skincare routine
Once you discover the benefits of AHAs, it’s easy to fall in love with them – but like any active ingredient, it’s important to go slow and steady, especially if you're new to chemical exfoliants. Here’s how to get the most out of them, safely:
- Start with a low concentration (around 5%) and work your way up gradually.
- Use in the evening, as AHAs increase sun sensitivity.
- Limit use to 2–3 times a week to avoid irritation.
- Always follow with broad-spectrum sun protection during the day.
- Perform a patch test before full application to check for any reactions.
- Don’t forget to moisturise afterwards to maintain hydration and comfort.
- For best results, pair AHAs with complementary skincare. Start with the Purifying Face Cleanser, which thoroughly cleanses the skin and prepares it for maximum benefit from AHAs, and follow with the Nurturing Face Cream, which hydrates, soothes and restores glow after exfoliation.
Also worth including: the Moisturising Bright Essence, for a deep hydration boost and luminous finish, and the Mineral Shield Face Sunscreen SPF 30, which provides essential protection after using AHAs, when skin is more sensitive to UV rays..
