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. If you see this, drink a glass of water. Stay hydrated!

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Benefits of Lactic Acid are that it can help to reduce large pores and reduce the effects of aging. Some potential downsides are that it can be bad for dry skin, cause irritation, worsen eczema, and worsen rosacea.
Not only does it help exfoliate the skin, it helps strengthen the skin's barrier. When applied, lactic acid helps the skin create ceramides.
Lactic acid is an over-the-counter chemical exfoliant that comes from the fermentation of lactose — a carbohydrate found in milk.
Legend has it that Cleopatra used to bathe in sour milk to help reduce wrinkles.

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 even out skin tone.
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.

This might just be a holy grail item for me. I have moderate hyperpigmentation with a small patch of melasma, and this has been the best at treating it. I love that it's fungal acne safe and has Vitamin C, Tranexamic acid, and Azelaic acid. The PHA is a bonus, and it has been quite gentle on my sensitive skin. Definitely will be repurchasing.
Holy grail. Enough said. This is worth the value. I know it's a toner, but it works like a serum, so it lasts forever making it the cheapest product I've ever bought. Not sure if it helps with dark spots, but it does make a massive difference in skin brightness and texture.
