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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

The Ordinary Salicylic Acid 2% Solution contains this as ingredient number 11.
Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

The Ordinary Salicylic Acid 2% Solution contains this as ingredient number 1.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

The Ordinary Salicylic Acid 2% Solution contains this as ingredient number 10.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Dependable anti-blemish and anti-marks serum for sensitive skin
This is a very good and gentle exfoliating serum for sensitive skin. It helped me get rid of some hormonal acne few years ago, cleared my skin and somehow made it more resistant to acids, which I had to be very carful with before. Its also good for treating backne.

Worth the try for ACNE skin
I used it for about 2 years and I was more than satisfied. Upon returning on my Erasmus trip, it broke me out and made my skin dry. I don't know if anything happened during the trip but right now I don't use it. It's really good if you have taken acne treatment pills and you need smt to keep the acne away (from my experience at least).

It is like gel consistency but it gets foamy when you try to spread across your face. Despite that, it works on my skin because acnes are getting smaller and my closed comadomes are slowly disappearing.
When it gets foamy after spreading across my face, i simply let it dry for like 30 seconds then put on other skincare.
