Ingredients Explained

These ingredients are found in both products.

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

Benzoyl Peroxide (BPO) is one of the most studied and widely used acne-fighting ingredients on the market for over five decades.

It works by releasing oxygen into your pores to kill Cutibacterium acne, or the bacteria closely linked to acne breakouts. This bacteria has a hard time surviving in an oxygen-rich environment.

On top of that, BPO has keratolytic properties to help shed dead skin cells and keep pores from getting clogged.

One of the coolest things about BPO is that bacteria do not develop resistance to it the way they can with antibiotics. That's why dermatologists recommend pairing it with topical antibiotics to keep resistance at bay.

BPO is usually available in 2.5%, 5%, and 10% concentrations. Research has shown that 2.5% tends to be just as effective as the higher strengths while being more gentle on the skin.

The FDA has classified BPO as a safe and effective acne treatment. You'll be able to find this ingredient in over-the-counter products in many countries.

Just so you know, BPO is a known mild irritant. It's common to see dryness, peeling, and some redness when you first start using it. This usually goes away as your skin adjusts.

A very small number of people might develop allergic contact dermatitis from it as patch test studies show positive reactions in about 1-5% of patients.

Once BPO is absorbed into the skin, our bodies turn it into benzoic acid and quickly exits in urine. It's also worth noting that BPO will bleach fabrics and hair, so watch your towels and pillowcases!

Disodium EDTA is a chelating agent. It grabs onto and deactivates metal ions that sneak into your products from water, packaging, or air.

This ingredient mainly works behind the scenes and helps with:

On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.

One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).

Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.

You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.

Propylene Glycol is a synthetic, colorless, odorless liquid that has been a staple in cosmetics for decades. It is a skin conditioning agent, humectant, and solvent.

As a humectant, it draw water to the skin to reduce flaking and restore suppleness. It's also a solvent that helps dissolve other actives and keeps formulas stable across temperature changes.

The CIR Expert Panel has confirmed this ingredient to be nontoxic and clinical studies show no sensitization at cosmetic use concentrations.

True allergic reactions are quite rare: a 15-year retrospective study of 6,751 patients found only 0.31% had a positive reaction (and less than half were considered clinically relevant).

It seemed that when sensitization does occur, it's most commonly linked to topical medication (like corticosteroids) and not cosmetics. Allergic contact dermatitis also appears largely limited to individuals with underlying skin conditions.

Overall, propylene glycol is a well-studied ingredient that most people can tolerate without issue.

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.

"Alkaline" refers to a high pH level. A low pH level would be considered acidic.
