Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Azelaic acid is a multitasker ingredient that helps treat acne, pigmentation, and irritation. It is a great option for sensitive skin.
What makes azelaic special?
The best thing about azelaic acid is it's gentleness. It's generally well-tolerated and safe to use alongside other actives like niacinamide or salicylic acid.
Unlike AHAs, azelaic acid will not make you photosensitive/sun sensitive.
You can find this ingredient naturally occurring in grains like wheat, rye, and barley. In cosmetics, azelaic acid is typically lab-made, which is more stable and effective.

Like other AHAs, it helps exfoliate the surface of the skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath.
Mandelic acid helps with:
Due to it having a larger molecular size than glycolic acid, mandelic acid is able to penetrate the skin more slowly and evenly. This makes it gentler and less irritating, making it a great option for sensitive or beginner skin.
Despite being milder, mandelic acid is still an effective exfoliant that improves skin texture and tone over time.
What makes mandelic acid stand out from other AHAs? It has antibacterial and antioxidant properties.
These traits make it a great option for acne-prone or problem skin by reducing active breakouts and fading post-acne marks. Studies show that mandelic acid (especially when combined with salicylic acid) can significantly reduce pimples and hyperpigmentation while causing fewer side effects than stronger acids.
Mandelic acid is effective in concentrations of 5% and up with an ideal pH range of 3-4 for at-home use.
Like other AHAs, it’s important to wear sunscreen daily to protect your newly exfoliated skin.
However, unlike glycolic acid, mandelic acid is light-sensitive. Be sure your mandelic acid is packaged in opaque containers to ensure it stays stable and effective.
In short, mandelic acid is a gentle yet powerful AHA that exfoliates, brightens, and helps clarify skin while keeping irritation low. Its antibacterial action makes it especially beneficial for those with acne-prone, sensitive, or uneven skin, offering smoother, clearer, and more even-toned results over time.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
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.

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!
