Very few beauty brands can capture attention for a long time and The Ordinary Skincare brand is one of those ones doing something right! Deciem (parent company) launched the brand a year or so ago and it’s still getting hype now. I mean their £4 serums in a world of £120 serums are a seriously good bargain. I have been testing out a few of their products (previous review on The Hyaluronic Acid Serum) and today’s post is a full review on The  Lactic Acid 5% & HA 2% serum. All about acids can be found here

The Ordinary describes this as The Ordinary Lactic Acid: a skin treatment serum for very mild skin 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.



The lactic acid comes in two strengths, a 5% and 10%, I decided to go with the 5% as this would be my first lactic acid serum and I wasn’t sure how my skin would react to it. My skin totally loves Glycolic acid and can tolerate that quite well at high % but lactic acid I wasn’t so sure. The 2% HA is hyaluronic acid

The Ordinary’s Lactic Acid 5% is a water solution with a slight yellow/amber colour. I apply this at night as my acid serum, after toner and before misting slightly with the B Confident Hyaluronic Acid Face Spritz (review pending). I have been using this for quite some time and (slightly) more than half way down the bottle.

Let’s talk texture and scent: it’s a water solution so it doesn’t have that serum consistency to it which I don’t really mind. It spreads easily and sinks quickly into the skin. It left a slight tingling sensation the 1st few times I used it, which I expected anyway as my skin was starting to get used to it. The tingling sensation goes away after the spritz dries. Nothing too major. Even after using this for some time, I would still get some sensation from time to time.

After using the serum, my skin feels nice and slightly glowy/dewy, like I have used an oil. Any skincare products I apply after this sinks right into the skin as well. I haven’t experienced any irritation with the Lactic Acid nor has it broken me out.

My only let down with the product is the scent: I hate it lol, it just smells like something that has gone off and it lingers too. I can overlook the scent because I like how it feels but I just can’t wait to finish this bottle! Lol

I have been using this with another serum and I am starting to see improvements in hyperpigmentation and general health of my skin. I also bring the Lactic Acid down my neck and chest areas and I haven’t had any issues with that


If you love Lactic Acid I suspect you will love this serum from the Ordinary. For my first time with lactic acid, I can say it’s nice but I definitely prefer Glycolic Acid which gives me faster results. The scent of this is a HUGE let down for me (I love scent and products that smell good) but it’s working so I can overlook that.

The Ordinary’s Lactic Acid serum has been compared to the Sunday Riley Good Genes which is an all in one Lactic Acid Treatment. Not sure how true this is as I have never used Good Genes

Will I repurchase? No

The Ordinary Lactic Acid 5% + 2% HA is £5.50 and available from Victoria Health

I am loving The Ordinary brand atm and they have extended their acids with two new acids: Glycolic Acid 7% (which I immediately bought 2 bottles of lol) and AHA 30% + BHA 2% Peeling Solution. Check out Victoria Health for more info on these. I have also recently hauled a few of their products, look out for reviews soon!
