Ingredients Explained

These ingredients are found in both products.

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

Skin Conditioning, Solvent

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!

Astringent, Skin Conditioning

Tranexamic Acid is best used for treating hyperpigmentation, discoloration, and melasma. It can also help build a stronger skin barrier.

Once applied, Tranexamic Acid starts decreasing inflammation from UV exposure. Tranexamic Acid also prevents our skin cells from meeting the pigment production cells.

Its brightening property makes it great at reducing the appearance of acne scars and marks.

Fun fact: Tranexamic Acid is also a medication used to reduce heavy bleeding.

This acid is derived from lysine, an amino acid.

When I first used this product I didn’t think it was doing anything but I continued to use it because it didn’t break me out. about 3-4 weeks later i’m looking back at old picture of my skin and it really does make a difference with dark spots. I was and currently using panoxyl 4% so maybe that played somewhat of a part but I do recommend this product for acne scars, dark spots but i didn’t find Show more

It’s been 3-4 months already since I started using this and it’s a great product. It’s lightweight, it didn’t irritate my skin at all and I also noticed that my skin really got brighter over time. However, it did little to nothing to fade my hyperpigmentation :( I’m guessing that my case is just really stubborn
