Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Water

What it does: Skin Conditioning, Solvent

Community Rating: Loved

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!

Citric Acid

What it does: Buffering, Masking

Community Rating: Disliked

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.

I was very excited about this serum, as the price point is wonderful and reviews described it to have a very light and watery consistency. Finally, the ingredient list I saw online was fragrance- and oil-free.

Unfortunately, the reality wasn't the case... After reformulation, now it contains almond oil (Prunus Amygdalus Dulcis Oil) which contributes to comedgenicity and quite a strong smell which lingers. Moreover, the serum is very sticky and hard to layer. Right after application, as soon as it dried down, I have a feeling like a slightly tight film is formed on my face, which starts pilling in combination with more than 1 product.

All in all, I definitely do not recommend it. However, I gave it two stars because I ended up using it on my arms for keratosis pilaris and it seem to be helping due to a good concentration of Sodium Ascorbyl Phosphate.
