The Ordinary Lactic Acid 10% + HA 2% - a high-strength lactic acid superficial peeling formulation.

Lactic Acid is an alpha hydroxyl acid that exfoliates the skin. This 10% formulation offers mild exfoliation and is supported with a purified Tasmanian pepperberry known to reduce signs of inflammation and sensitivity that is often associated with exfoliation.

This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time.

This pH of this formula is approximately 3.8. Lactic Acid has a pKa of 3.8 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximising effectiveness of the acid and reducing irritation. Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic.

Alcohol-free, nut-free, vegan.

Note: While Lactic Acid can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids.

Directions

Apply once per day, ideally in the PM. Can be diluted with other treatments to reduce strength until skin develops tolerance.

Lactic Acid should not be used on sensitive, peeling or compromised skin. Avoid contact with eyes. If irritation persists, discontinue use and consult a physician. 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.

Rated 3 out of 5 by from Still confused I bought this almost a year ago and I still find myself going to the internet to try and understand it. PLEASE put more instructions on your packaging. Also, how does everyone avoid ripping off their fingerprints when applying?

Rated 5 out of 5 by from Needs a bigger size Literally the best lactic serum I have used in my 6 years of skincare. We need a 120ml because the 30ml only lasts about a week or 2 of usage.

Rated 4 out of 5 by from Does the job Simple formulation that does a nice job exfoliating while and plumping up the skin. I use this maybe once a twice a week, a small drop at night time only, after cleanse and a hydrating serum, topping with a light moisturiser in winter months. I find my skin smoother and firmer in the morning after using this. Of course, it's important not to exaggerate (not to use too much or too frequently), and to follow with barrier repairing skincare and sun protection.

Rated 5 out of 5 by from Best Product I have purchased this product multiple times. It works overnight to give you smooth, hydrated, and glowy skin in by the morning.

Rated 5 out of 5 by from Great product! I have been using the Lactic Acid 10% +HA for around a month now and my skin feels so hydrated and smooth. I actually noticed the difference the first time I used it. Little bumps on my forhead dissapeared in a week and my skin was really smooth. I use this under a mosturiser at night and my skin feels very hydrated.

Rated 5 out of 5 by from KP problem solved! I bought this about a month ago and hoped it would work…. It has! It’s surpassed all of my expectations! Background: I have KP (keratosis pilaris) and I have tried everything on the market to get rid of a few problem areas on my arms and around my knees. None of the expensive creams, soaps, exfoliators, or scrubs have worked. I’ve even tried home remedies! I applied a dropper full to each area that was bumpy & rough after each shower for 3 weeks and the bumps are gone!!!! I’m going to keep this on hand forever! Thank you The Ordinary! I have the smoothest skin I’ve ever had in my entire life! Love!

Rated 3 out of 5 by from Is this a wash off treatment or a leave-on? I don't have a review yet, as I just purchased a bottle of the Lactic Acid exfoliating serum today. I'm a bit confused as to how this should be used. Is this a treatment that you leave on for a few minutes (or 10, 15 minutes?) and then wash off? Or, do you apply it after cleansing and leave it on?

Can I use this in combination with the Glycolic acid? I have blemishes from past acne that are dark on my face. Everytime I get a new one is very likely to leave a “stai 

Asked by: Alice
Lactic and glycolic acids are both used as skin exfoliants. Lactic acid can be less irritating than glycolic and I wouldn't use both at the same time. For reduced pigmentation on the skin after blemishes I'd use azeliac acid added to your skin routine.

Please can you tell me does this help with wrinkles? I am looking into it for my mother has has wrinkles due to sun exposure in younger days without spf! 

Asked by: Lianne
It’s not specifically designed for wrinkles, it mainly exfoliates your face. Retinol might be better for your mum

Hi, can I use this with the Holland and barret vitamin e oil. It contains Sunflower Oil, Vitamin E (as d-Alpha Tocopheryl) (Soya), Lemon Oil. 

Asked by: Zakia
Hi there, Thanks for reaching out to us. Lactic acid is an exfoliating, active ingredient so you can use this with your oil as it doesn't contain any exfoliating ingredients. I hope this helps! Many thanks, Laura - Customer Care Advisor

After I’ve applied this do I then apply my usual serum and night cream? Thank you

Asked by: Mrs
Hey there, If you have not used Lactic Acid before, we would recommend using the The Ordinary Lactic Acid 5% + HA 2% to start with while you skin adjusts to this acid. You would apply this exfoliating acid once per day, ideally in the PM as the first serum in your routine after cleansing and toning followed by a serum (if you wish) and your moisturiser. It can be diluted with other treatments to reduce strength until skin develops tolerance. As this product is exfoliating, we would highly recommend using and SPF in the day when using Lactic Acid and to avoid other acids/ retinols when using this product. Hope this helps! Many thanks Katie, Beauty Expert.

Hi which is best for exfoliating and blemishes, while pregnant? I was told to stop using glycolic acid:( Thanks

Can i use this together with Niacinamide? 

Asked by: Junna Nelia
Hey there, This can be used with the The Ordinary Niacinamide 10% + Zinc 1%. You would use The Ordinary Niacinamide 10% + Zinc 1% in the morning after cleansing and The Ordinary Lactic Acid 5% + HA 2% in the evening after cleansing (start with the lowest formula if you have not used Lactic Acid before so your skin can adjust to the foreign substance). Hope this helps! Many thanks Katie, Beauty Expert.

Can I use it with vitamin c solution and azeluic acid ?

Asked by: Anne
Hi, We would not advise using The Ordinary Lactic Acid 10% + HA 2% alongside products containing Vitamin C as both ingredients have exfoliating properties, this means that using them together may over process the skin and cause some irritation. Hope this helps! Thanks Katie, Beauty Expert.
