Mandelic Acid Explained: Why it has become so popular in skincare

What Is Mandelic Acid?

Mandelic acid is an alpha hydroxy acid (AHA) naturally derived from bitter almonds.

Unlike glycolic acid, mandelic acid has a larger molecular size, which means it penetrates the skin more slowly. That slower penetration makes it less irritating while still encouraging healthy cell turnover and smoother, brighter skin.

Because of those properties, mandelic acid has become a favourite ingredient among skin professionals treating:

Acne
Congestion
Pigmentation
Sun damage
Fine lines
Uneven skin tone

Why We Love Mandelic Acid at Maxwell’s

Mandelic acid offers multiple benefits in one ingredient.

Helps clear acne

Mandelic acid gently exfoliates inside pores, helping reduce congestion while encouraging healthier skin renewal. You will find it doing exactly that in our AHA/BHA Purifying Gel, where mandelic acid leads a time released blend formulated for skin that has not tolerated glycolic or salicylic acid well in the past.

Brightens pigmentation

By increasing skin cell turnover, mandelic acid helps gradually fade post-inflammatory pigmentation and sun damage. That is the thinking behind our Skin Resurfacing Complex, which pairs mandelic acid with glycolic acid in an amino acid complex designed to lift discolouration with minimum discomfort.

Smooths skin texture

Regular use helps refine rough skin and improve overall texture.

Supports healthy ageing

By stimulating healthy skin renewal, mandelic acid helps soften the appearance of fine lines and maintain smoother-looking skin.

Suitable for sensitive skin

Because it penetrates more slowly than many other AHAs, mandelic acid is often better tolerated by sensitive skin and darker skin tones.

Who Should Use Mandelic Acid?

Mandelic acid suits people dealing with:

Adult acne
Hormonal breakouts
Blackheads
Enlarged pores
Pigmentation
Sun damage
Uneven texture
Early signs of ageing

Using Mandelic Acid in Your Routine

Mandelic acid works best as part of a simple routine rather than on its own. Three steps cover it.

Cleanse

Start with a wash that lifts oil and surface debris without stripping the skin. Our Purifying AHA/BHA Cleansing Foam uses glycolic acid and betaine salicylate to do that, so your mandelic acid treatment goes onto clean skin and can work properly.

Treat

Apply your mandelic acid product to dry skin, usually at night. Start with two or three nights a week and build up as your skin adjusts. Slow and steady beats aggressive, which is the whole point of choosing mandelic acid in the first place.

Protect

Any AHA leaves skin more sensitive to UV, so daily SPF is not optional. Sunscreen every morning protects the results you are paying for, and it matters most when you are treating pigmentation.

If you are not sure which strength suits your skin, our clinicians will assess it and set the routine for you. You can book a consultation online or call the clinic on (07) 5591 1744.

Frequently Asked Questions

Is mandelic acid good for acne?

Yes. It helps reduce congestion, gently exfoliates pores and improves post-acne marks.

Is mandelic acid better than glycolic acid?

Not necessarily. It depends on your skin. Mandelic acid is often preferred for sensitive or acne-prone skin because it is gentler.

Can sensitive skin use mandelic acid?

In many cases, yes. Its larger molecular size allows slower penetration, which makes it one of the gentler exfoliating acids available.

How often should I use mandelic acid?

That depends on the strength of the product and your skin goals. Your clinician can recommend the right routine for your skin.

Do I still need sunscreen while using mandelic acid?

Yes, every day. Exfoliating acids leave fresh skin at the surface, and unprotected sun exposure will undo the brightening you are working towards.
