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!

Biologique Recherche Complexe Iribiol Rebalancing and Purifying Serum for the Face contains this as ingredient number 1.
Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Biologique Recherche Complexe Iribiol Rebalancing and Purifying Serum for the Face contains this as ingredient number 4.
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.

Phytic Acid is a gentle AHA and antioxidant. The chemical makeup makes it classified as an AHA, such as lactic acid.
AHAs are chemical exfoliants that help remove dead skin cells. Phytic Acid has a slight exfoliating effect. Phytic Acid has been shown to help calm irritation. In some cases, it is a chelating agent. Chelating agents help prevent metals from binding to water, helping to stabilize the ingredients in a product.
As an antioxidant, phytic acid may help with the signs of aging. Antioxidants help neutralize free-radical molecules. These molecules may damage your skin cells.
An interesting fact about phytic acid is that it is considered an antinutrient. People do not have the enzyme needed to properly breakdown and digest phytic acid. When ingested, phytic acid binds to minerals and prevents them from being absorbed.

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).
