Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterLactic Acid is an AHA that is derived from fermenting lactose, a carbohydrate from milk. It removes the top layer of old and dead skin cells and helps increase cell turnover.
Benefits of Lactic Acid are that it can help to reduce large pores and reduce the effects of aging. Some potential downsides are that it can be bad for dry skin, cause irritation, worsen eczema, and worsen rosacea.
Not only does it help exfoliate the skin, it helps strengthen the skin's barrier. When applied, lactic acid helps the skin create ceramides.
Lactic acid is an over-the-counter chemical exfoliant that comes from the fermentation of lactose — a carbohydrate found in milk.
Legend has it that Cleopatra used to bathe in sour milk to help reduce wrinkles.

The Ordinary Lactic Acid 5% + HA 15 ingredients
Holy grail for real. This stuff works instantly overnight to sooth acne and balance skin tone/texture. Everytime I do some damage picking at my skin, this serum basically undoes it all. Fantastic for maintenance whilst purging acne, I use this in rotation with the inkey list BHA serum and they have resurfaced and evened out all my fungal acne, going to move onto the 10% for clearing up my scars Show more
🤍 been using this for 2 years now, and i've really seen significant changes in my skin—especially with hyperpigmentation and texture ♡ however, it can be a bit irritating since i have sensitive skin, and it feels a little harsh when i combine it with the niacinamide 10% + zinc from the ordinary too. so, on my heavier days where my skin is extra sensitive, i skip this serum and just use moisturizer Show more

This is my holy grail toner. I've literally used 9 bottles so far, and am currently using another one.
The first time I ever used it, I thought it was just nice but not necessarily more special than other toners I had tried. However, after a week of using it, I noticed visible improvements. My skin was looking noticeably more hydrated, more even, more healthy. Turns out my skin just loves this Show more
My favorite toner! The lactic acid and urea keep fungal acne at bay and it pairs well with other products. It’s hydrating and works great for my sensitive skin. It is gentle enough to use even if my skin is irritated, unlike other toners I have.
