The Ordinary Lactic Acid 10% + HA 2% 30ml
Product Description
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.

Good for skin texture
I've been using this for a month now and I'm finally starting to see a difference. My skin is smoother and brighter. The night I first used it I noticed how smooth my skin felt the following morning but I did purge pretty quickly within the first week of using it. I also sometimes get those tiny bumps on my forehead and this has helped them a bit but it did take a few weeks before it began to smoothen out. I have dry sensitive skin and have had no issues using this 10% version though the first few weeks I did mix it with a moisturizer starting with just 1x a week but now I use it every 3-4 days without mixing. I will say making sure your skin is hydrated and moisturized while using this is so important as well as wearing sunscreen during the day because it can make your skin sensitive to the sun. I like this product and will be repurchasing.

A staple to my skin care routine
Open using this for years, usually only at night. I just started using it during the day a couple times a week as well. Is an amazing product. Keeps my skin, bright and clear, and I think it also helps minimize or make my lines not look so sharp. I’m 55.

LOVE THIS PRODUCT!
I love this product. I was skeptical in the beginning because I have the peeling solution. I do not use this when I use the peeling solution. Now my face is smooth and decongested. My skin tone is more even now than it ever was.

Caused Breakouts After a few Uses
I used Lactic Acid three times, and unfortunately, my face broke out with small pimples.
I previously used Peptide + Copper and Vitamin C + F serum without any issues. However, now I’ve started using Lactic in the night and Argireline and Copper in the mornings, and I’ve been breaking out.

The only product that works
The only product that seems to work for me in terms of smoothing my skin and reducing imperfections. Swear by it. I have tried other acids and nothing has worked like this.

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
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!
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.
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,

Hi, do you leave the lactic acid on your face then moisturise or do you wash it off then moisturise ? Thanks
I leave it on then apply moisturiser on top

After I’ve applied this do I then apply my usual serum and night cream? Thank you
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
Hey there,
We encourage those who are pregnant or breastfeeding to consult with a healthcare professional before using any products. This is because we cannot guarantee they have been tested under these conditions so we cannot guarantee there safety.
Many thanks Katie, Beauty Expert.

Can i use this together with Niacinamide?
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 ?
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.
