Learn more about WaterGlycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

The structure of Sodium Hyaluronate Crosspolymer allows it to stay in the skin's top layer for a longer period of time. This allows for even more hydration and humectant action than hyaluronic acid.

I’ve been using this for a week now on sensitive and reactive skin. So far I’ve had no bad response, no irritation or breaking out. I now use it only at night because it is slightly sticks and takes a while to absorb. I believe some results are there - dark marks slowly fading.
(I am trying this to compare with Skin1004 tone brightening capsule ampoule - which I really like and used to use morning and night).
I will update again after a couple of weeks

Speaking anecdotally, please be very well informed and careful if you choose to use this product. While this product contains both AHA and BHA chemical exfoliants I will be emphasizing its AHA content as a potential safety/irritant concern to the skin. Alpha hydroxy acids in this concentration can very easily over-exfoliate by stripping corneocytes from, or desquamating, the outermost stratum corneum of the epidermis. While this product formulation is vague about specific AHA composition of “30%”, The Ordinary’s website states that glycolic acid is the primary alpha hydroxy acid in their formula. Current clinical research (and the FDA) has established a general consensus that the concentration of AHAs for safe routine use in over the counter products is approximately in the figure range of 2-10%. For reference, dermatologists with over 8 years of medical and residency training perform chemical peels with glycolic acid ranging in concentration anywhere from 20-70% depending on intended penetration of the stratum corneum. With that said, there are some individuals with skin who can tolerate this level of exfoliation, but my personal philosophy is that less is more with chemical exfoliants. If you are thinking about using this product please do your due diligence and look into open-access research on chemical exfoliants, consider all exfoliant options side-by-side/if a chemical exfoliant is right for you, and understand your skin’s sensitivity level before jumping to one product.

one of my fav chemical exfoliators. i recommend this for people with oily/acne-prone skin, those with dry or sensitive types should probably avoid.
NOTES: please be careful with this. i’ve seen so many people use this product incorrectly and would end up getting a bad reaction (like literally burning their face). then leave bad review without having used it properly. this is a CHEMICAL exfoliating peel, it will sting but it should NEVER burn. if it does, your skin either cannot handle it or it was applied wrong.
here’s how to make sure it’s being used correctly:
- don’t use it with any clashing ingredients in your other products. (ex: vitamin C)
- don’t use it if you have open wounds (picked pimples)
- make sure your skin is completely dry before application, only use 2-3 drops or enough to cover your face.
- it should be a thin red layer, not thick, or you’ll burn your skin.
- AVOID APPLYING ON EYE AREA
- do NOT leave it on for more than 10 minutes, even if you don’t feel anything. you will completely strip and damage your skin.
- make sure to use sunscreen every morning while using this.
i use this once a week at night time after i cleanse my face. i first started to notice a difference after a couple weeks of use, my breakouts were disappearing and it reduced the bumps on my skin. it does an excellent job of improving skin texture and removing blackheads/blemishes. my skin always feels so smooth after use. it helped a lot of my dark spots and acne scars fade. i also love how cheap this is, a holy grail under $10.
the only things i don’t like about this is the sensation and smell. it doesn’t hurt (no skincare product should anyway) but it does sting, which is to be expected of. it has a weird smell to it, i’m not sure how to describe it but it’s not bad. i personally don’t mind fragrance as it doesn’t bother my sense of smell or irritate my skin. this product could be irritating to others though. it all entirely depends on your skin.
