The Ordinary Mandelic Acid reviews by the moderators of the Facebook Group and the Deciem Addicts. Reviews by you, the people who have bought, tried and tested.

What is Mandelic Acid and what does it do?

Mandelic Acid 10% + HA offers superficial dermal peeling that is gentler than other alpha hydroxy acids. The molecular weight of mandelic acid is 152.1 daltons, which is larger than other alpha hydroxy acids (glycolic acid is 76.0 daltons, for example). This larger size allows mandelic acid to penetrate the skin more slowly which in turn makes it very gentle and suitable for all skin types. You don’t need a concentration of more than 10%, because then you would simply be achieving an indirect peeling strength that is more easily offered through lower percentages of glycolic acid.

This formulation offers superficial dermal peeling to target uneven tone, textural irregularities, and fine lines. Due to its large molecular weight, Mandelic Acid is suitable for all skin types (including those that are sensitive).

How & When Do I use Mandelic Acid

Mandelic Acid is a water-based product and should be used as one of the first layers in your routine followed by your oils or creams. Mandelic Acid can be applied once per day, ideally in the PM (please see sunburn alert below). It can be diluted with other treatments (check conflicts) to reduce strength until skin develops tolerance.

Avoid contact with eyes. Contact of the product with the skin must be of limited frequency or duration. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our in-depth guide to patch testing. Keep out of reach of children. 

Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin’s sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.

Which products conflict with Mandelic Acid?

You can find a chart listing all The Ordinary products you can and cannot mix here. Mandelic Acid shouldn´t be used in the same regimens as;

  • Direct Acids
  • Peptides
  • EUK 134 (Antioxidant)
  • Whilst not listed as a conflict, Deciem recommend avoiding the use of Pure Vitamin C and Retinols.

Which products can I use with Mandelic Acid?

This is the response from Deciem about Acids & Peptides.

Our rule against combining strong antioxidants only applies to our products containing copper peptides. We would not recommend combining direct acids with peptides due to the susceptibility of peptides to hydrolysis (which breaks the bonds between peptides, reducing their efficacy and making them into individual amino acids). At low pH, the peptides undergo processes such as deamidation (the removal of an amide group) and oxidation, which compromise the activity of the peptides.

Having said that, if you have previously combined peptides with acids and have not experienced any negative side effects or discoloration, you may continue to combine the two products as so as the combination does not pose any potential harm. Our recommendations are meant to serve as a preventative measure to avoid any incompatibility between those combinations and also because skin tolerance in subjective.

TTH says: I’m currently using Mandelic Acid. I am fairly new to chemical exfoliation and I have dry- combination skin, rather sensitive and acne prone. I use The Ordinary Mandelic Acid every evening after cleansing and I apply it as I would a serum. I like it, I have seen some improvement in my skin but I will for sure be picking up some lactic acid when this is finished 🙂

MVL says:  I used The Ordinary Mandelic Acid a couple of times and always felt that my skin was softer the other day. I am not using it now because of tretinoin, maybe I’ll use it once my skin gets used to tretinoin.

Mandelic Acid FAQS

Some of these Q&As have been copied from the Deciem Instagram

I have dry skin and recently have been dealing with some texture and a couple break outs, would the Mandelic Acid be good for me and which other products would you recommend? Deciem says: Mandelic Acid would be a great place to start. We would also suggest trying The Ordinary Niacinamide 10% + Zinc 1%. This is a high-strength vitamin and mineral formula that visibly targets the look of blemishes and signs of congestion. We recommend avoiding unprotected solar exposure, gradually incorporating one new product into your regimen at a time and applying test patches first to see what works best for your skin. We hope this helps! ❤

Can Mandelic Acid and Niacinamide be used together in the same routine? If so, in what order should they be applied? Deciem says: Yes, The Ordinary Mandelic Acid 10% + HA may be applied before Niacinamide 10% + Zinc 1%. ❤

Hi! Can I use the Glycolic acid toner in the same routine as Mandelic acid? Deciem says: We suggest using them on alternate evenings and waiting until your skin has adjusted to one before introducing another. 

More FAQS

Which of your products is good for blackheads? Deciem says: We would suggest exploring both The Ordinary Niacinamide 10% + Zinc 1% and The Ordinary Mandelic Acid 10% + HA. 

When you use this in the PM should you use it alone or add hyaluronic on top of it? Also can I put moisturizer on after applying it in PM or best not to? ou may use it alone or pair it with a hydrator.

Do you recommend using Mandelic and Lactic Acid together in a night regimen? We suggest using them on alternate evenings to avoid any irritation.

Would I be able to use the Salicylic Acid 2% Mask while using the Mandelic Acid? We suggest alternating between them to avoid irritation.
