Matte Benzoyl Peroxide Complexion Treatment 10%Ingredients explained
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product.
It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
The gold standard topical ingredient in treating acne. There is no miracle cure for acne (we do really wish for one, *sigh*), but Benzoyl Peroxide (BP) is probably the closest thing we have. But, as usual, big effects come with big side effects, so we think BP is best used as a last resort (at least, in the topical treatment field).
The good thing about BP is that it is amazingly effective against inflammatory-type acne. Not so much against blackheads or whiteheads, but against acne that is caused by the evil bacteria called Propionibacterium acnes (and that is most types of acne). Apart from being antibacterial, it is also anti-inflammatory, keratolytic and wound-healing, all of which are properties that make it so darn effective against spots.
Another big pro of BP is that there is no bacterial resistance to it, meaning if it works once it will continue to work. Antibiotics are also a common way to treat acne, but antibiotic-resistant P. acnes are increasing worldwide. BP will probably help you even if antibiotics have stopped working, and the two are also often combined for a more complex acne therapy. Btw, BP plays nice not only with antibiotics but also with retinoids.
The side-effects part? BP works its antibacterial magic by being a powerful oxidizing agent, meaning it is a pro-oxidant. As in the opposite of an antioxidant. BP literally generates evil ROS (reactive oxygen species) in the skin that kills P. acnes but also harms the surrounding skin cells. Ongoing BP-use ages your skin, which is why, we say, use it as a last resort. If you do use BP, please also use a good sunscreen and a good antioxidant serum to apologise to your skin (btw, these things are useful in any case). Use the BP treatment at night and the antioxidant serum in the morning so that they do not cancel each other out.
Another side effect of BP is that it can be very skin drying. BP is an example where more is not better. In fact, it is equally effective at concentrations of 2.5, 5.0 and 10%, but the higher the concentration the more irritating and drying side effects occur. So using BP at 2.5% percent is the ideal amount. Another side effect which is good to know is that BP can bleach bedsheets and clothes. Be careful with your expensive satin bedsheets.
Overall, Benzoyl Peroxide is a uniquely effective topical acne treatment, but it comes at a price. Use it as a last resort and for good measure (and with plenty of moisturizers, sunscreen, and antioxidant serum).
- It’s the most researched AHA with the most proven skin benefits
- It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
- It can help skin’s own collagen production that results in firmer, younger skin
- It can fade brown spots caused by sun damage or PIH
- Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
- Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)
- Slight stinging or burning with a stronger AHA product is normal
- If your skin is very sensitive, rosacea prone choose rather a BHA or PHA product
- It's one of the gold standard ingredients for treating problem skin
- It can exfoliate skin both on the surface and in the pores
- It's a potent anti-inflammatory agent
- It's more effective for treating blackheads than acne
- For acne combine it with antibacterial agents like benzoyl peroxide or azelaic acid
- It’s the second most researched AHA after glycolic acid
- It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
- It also has amazing skin hydrating properties
- In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles
- Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
- Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)
An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%.
It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols. Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating and are totally ok for the skin.
It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like. Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-called rheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range.
Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It’s approved by Ecocert and also used in the food industry (E415).
Aloe Vera is one of today’s magic plants. It does have some very nice properties indeed, though famous dermatologist Leslie Baumann warns us in her book that most of the evidence is anecdotal and the plant might be a bit overhyped.
What research does confirm about Aloe is that it’s a great moisturizer and has several anti-inflammatory (among others contains salicylates, polysaccharides, magnesium lactate and C-glucosyl chromone) as well as some antibacterial components. It also helps wound healing and skin regeneration in general. All in all definitely a goodie.
Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA.
So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.
There is also some research showing that citric acid with regular use (think three months and 20% concentration) can help sun-damaged skin, increase skin thickness and some nice hydrating things called glycosaminoglycans in the skin.
But according to a comparative study done in 1995, citric acid has less skin improving magic properties than glycolic or lactic acid. Probably that’s why citric acid is usually not used as an exfoliant but more as a helper ingredient in small amounts to adjust the pH of a formulation.
