Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Sulfur is a commonly occurring element on Earth (and our universe!). In cosmetics, it helps kill bacteria, reduces sebum, and provides exfoliation. This makes it an effective ingredient to reduce breakouts and fight acne.
As a ketayolytic agent, it breaks down the top layer of skin. This is a form of exfoliation and may help decrease acne and hyperpigmentation.
Studies show sulfur has antibacterial and antifungal properties. Sulfur can be drying if used excessively or at higher concentrations. We recommend speaking with a medical professional if you have any concerns.
Ancient Greece, India, China, and Egypt have used sulfur in both traditional medicines and for household use.

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!
Learn more about WaterNiacinamide 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.

Its main role is to remove the top layer of dead skin cells, allowing newer skin cells to emerge.
Specifically, AHAs work by breaking down the structural "glue" holding the old skin cells in place. Getting rid of the old skin cells allows skin to regenerate newer skin cells in its place. A build up of dead skin cells can lead to tired and dull looking skin.
Due to this, glycolic acid helps with:
Fun fact: Glycolic acid increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.
When starting glycolic Acid, it is normal to feel slight stinging.
The pH value and concentration of glycolic acid play a role in the effectiveness of the product. Concentrations between 5-20% glycolic acid have been shown to be effective in clinical studies.
Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

Fatty Alcohols are most often used as an emollient or to thicken a product. Emollients help soothe and hydrate the skin by trapping moisture.
They are usually derived from natural fats and oils and therefore do not have the same drying or irritating effect as solvent alcohols. FDA allows products labeled "alcohol-free" to have fatty alcohols.
Learn more about Stearyl AlcoholGlycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Cetearyl alcohol is a mixture of two fatty alcohols: cetyl alcohol and stearyl alcohol. It is mainly used as an emulsifier. Emulsifiers help prevent the separation of oils and products. Due to its composition, it can also be used to thicken a product or help create foam.
Cetearyl alcohol is an emollient. Emollients help soothe and hydrate the skin by trapping moisture.
Studies show Cetearyl alcohol is non-toxic and non-irritating. The FDA allows products labeled "alcohol-free" to have fatty alcohols.
This ingredient is usually derived from plant oils such as palm, vegetable, or coconut oils. There is debate on whether this ingredient will cause acne.
Due to the fatty acid base, this ingredient may not be Malassezia folliculitis safe.

As an emulsifier, Ceteareth-20 prevents oil and water from separating. It is also a surfactant. Surfactants help gather oil, pollution, and dirt to be washed away.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Phenylethyl Resorcinol (PR) is a synthetic antioxidant and tyrosinase inhibitor. This ingredient is found naturally in pine trees.
What is a tyrosinase inhibitor?
Tyrosinase is an enzyme that plays a key role in melanin production, which leads to skin darkening when exposed to UV light. By inhibiting this enzyme, PR can help with skin brightening and lifting dark spots.
The manufacturer states 0.5% of PR is more effective than 1% kojic acid. In 2013, a study of 80 participants found combining PR with other skin-brightening ingredients found 57% showed moderate improvement and 17% saw no change. Another study with 20 women reported a 43% reduction in uneven skin tone.
While more research is needed to fully confirm PR's efficacy, there’s no harm in trying it - especially when combined with other proven skin-brightening ingredients.

LITERALLY WHY DOES NO ONE TALK ABOUT THIS??? A holy grail!! I put it locally on pimples and leave it all night long - a lifesaver when I break out - and wash it off in the morning, it definitely makes them deflate or accelerate the growing process (which makes it easier for pimple patches to treat the pimple!!)
It has a slight scent of sulfur but it’s honestly not a problem for me since it does Show more
