Sunday Riley Saturn Sulfur Spot Treatment Mask
Ingredients explained

Sulfur (10%) - goodie
What-it-does: anti-acne, antimicrobial/antibacterial | Irritancy: 0 | Comedogenicity: 0-3

A yellowish element that smells of rotten eggs and it might be familiar to you from the periodic table (has the symbol S in there).  It has a long history of medicinal use thanks to its antifungal, antibacterial and keratolytic activity.   It used to be a very common ingredient in the treatment of inflammation-related skin diseases such as acne, rosacea and seborrheic dermatitis, however, due to its malodorousness, it is less popular nowadays. 

Sulfur's precise mechanism of action is not known, but we do know that its effectiveness depends on its direct interaction with the skin surface, meaning the smaller the particle size, the better the effect. The United States Pharmacopeia lists two types of sulfur, sublimed and precipitated. The latter one has a smaller particle size and counts as a superior version. 

Also-called: Aqua;Water | What-it-does: solvent

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. 

What-it-does: emollient

An odorless and colorless emollient ester (cetyl alcohol + ethylhexanoic acid) that gives a velvety and silky feel to the skin. It has great spreadability and a non-oily feel. It's a popular ingredient in makeup removers.

What-it-does: emollient

A naturally derived (Ecocert approved) colorless to yellowish oily liquid that's touted as a natural silicone alternative. It's claimed to have great sensorial properties: light but caring, velvety, silky and non-sticky.

It's also great at dissolving UV-filters in sunscreens or dispersing pigments in makeup products. You can also bump into Isoamyl Laurate in hair care products as a hair conditioner that makes combing easier without build up.

Niacinamide - superstar
Also-called: vitamin B3, nicotinamide | What-it-does: cell-communicating ingredient, skin brightening, anti-acne, moisturizer/humectant
  • A multi-functional skincare superstar with several proven benefits for the skin
  • Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration
  • Fades brown spots alone or in combination with amino sugar, acetyl glucosamine
  • Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration
  • Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis

Also-called: Acacia Senegal Gum

A natural polymer (big molecules from repeated subunits) that is harvested from the Acacia tree in the sub-Saharan region in Africa. It's a great thickening and binding agent. Often coupled with xanthan gum, as it helps to reduce its unpleasant stickiness.

Also-called: Sepinov EMT 10 | What-it-does: viscosity controlling, emulsion stabilising

This long-named, polymer molecule (big molecule from repeated subunits) is a helper ingredient that's good at emulsifying and stabilizing oils into water-based formulas. It also acts as a thickening and gelling agent that creates nice, non-sticky and supple textures. It works over a very wide pH range (3-12) and can be used to thicken up low-ph formulas, such as exfoliants. Its recommended used range is 0.3-3%.

Bentonite - goodie
Also-called: Type of clay | What-it-does: viscosity controlling, absorbent/mattifier, emulsion stabilising | Irritancy: 0 | Comedogenicity: 0

When it comes to oil-absorbing clay masks, bentonite will probably be one of the first ingredients on the INCI list. Technically bentonite clay is mostly montmorillonite + something else, and thanks to the something else bit, bentonite comes in different types and colors

The color depends on the mineral content of the clay: white bentonite is rich in boron and fluoride, yellow is rich in manganese and zinc, green is rich in copper, zinc, and manganese and the pink clay is rich in boron.

What-it-does: emollient, emulsifying

An olive oil derived ingredient modified to be water-dispersible while also keeping the original properties of olive oil. While being an emollient, it also has a very gentle cleansing action and can be used as a co-emulsifier and enhancer in cleansing products.

What-it-does: emulsifying

A multi-functional emulsifier that helps water and oil to nicely mix together. It also has a nice skin feeling, can act as a thickener and has some antimicrobial activity that makes it an active ingredient in some natural deodorants. 

Zinc Pca - goodie

If you have oily, acne-prone skin, Zinc PCA is one of the actives to put on your "TO TRY" list.

It's a synergistic association of two great things: Zinc and L-PCA. The Zinc part is there to help normalize sebum production and limit the proliferation of evil acne-causing bacteria. L-PCA stands for pyrrolidone carboxylic acid and it's a key molecule in the skin that helps with processes of hydration and energy (it's actually an NMF, a natural moisturizing factor).

What-it-does: emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 0

It's a common little helper ingredient that helps water and oil to mix together. Also, it can help to increase the solubility of some other ingredients in the formula. 

Also-called: Manuka Essential Oil | What-it-does: antimicrobial/antibacterial, antioxidant

The essential oil coming from the Manuka tree native to New Zealand. It is distantly related to the Australian Tea Tree Oil, although their chemical composition is very different.

The main antibacterial active in tea tree oil is terpinen-4-ol (40%), while manuka's main actives are so-called cyclic triketones, such as Leptospermone, Iso-leptospermone, and Flavesone (20-30%). Both oils are antibacterial and antifungal but in different ways.

Also-called: Licorice | What-it-does: soothing, moisturizer/humectant

The salt form of one of the main anti-inflammatory ingredients in the licorice plant, monoammonium glycyrrhizinate. It’s a yellowish powder with a nice sweet smell. 

It’s used mainly for its soothing and anti-inflammatory properties, but according to manufacturer info, it’s also sebum regulating so it's a perfect ingredient for problem skin products. 

Allantoin - goodie
What-it-does: soothing | Irritancy: 0 | Comedogenicity: 0

Super common soothing ingredient. It can be found naturally in the roots & leaves of the comfrey plant, but more often than not what's in the cosmetic products is produced synthetically. 

It's not only soothing but it' also skin-softening and protecting and can promote wound healing.

A mildly viscous, amber-colored liquid with fatty odor, made from Castor Oil and polyethylene glycol (PEG).

If it were a person, we’d say, it’s agile, diligent & multifunctional. It’s mostly used as an emulsifier and surfactant but most often it is used to solubilize fragrances into water-based formulas.

What-it-does: chelating

Super common little helper ingredient that helps products to remain nice and stable for a longer time. It does so by neutralizing the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.

It is typically used in tiny amounts, around 0.1% or less.

Tocopherols - goodie
Also-called: Vitamin E;Tocopherol | What-it-does: antioxidant | Irritancy: 0-3 | Comedogenicity: 0-3
  • Primary fat-soluble antioxidant in our skin
  • Significant photoprotection against UVB rays
  • Vit C + Vit E work in synergy and provide great photoprotection
  • Has emollient properties
  • Easy to formulate, stable and relatively inexpensive
Read all the geeky details about Tocopherol here >>

  • It's a super common and super debated skincare ingredient
  • It has several benefits: great solvent, penetration enhancer, creates cosmetically elegant, light formulas, great astringent and antimicrobial
  • It can be very drying if it's in the first few ingredients on an ingredient list
  • Some experts even think that regular exposure to alcohol damages skin barrier and causes inflammation though it's a debated opinion (read more in geeky details tab)

Also-called: Turmeric Root Extract | What-it-does: antioxidant, soothing, skin brightening, perfuming

Turmeric is the yellow spice you probably know from curry and Indian food. It's also a traditional herbal medicine used in Ayurveda for its bunch of anti-something magic abilities including being anti-inflammatory, antimicrobial, antioxidant and anticarcinogenic. 

As for turmeric and skincare, we have good news: studies show that the root extract and its main biologically active component, curcumin can do multiple good things for the skin. Thanks to its anti-inflammatory and antimicrobial activity, it shows some promise for acne-prone skin and a small study from 2013 showed that it might be able to regulate sebum production

We don't have description for this ingredient yet.

What-it-does: preservative

It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.

It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic. 

It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol

The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.

A little helper ingredient that works as a preservative. It works against bacteria and some species of fungi and yeast. It's often combined with IT-preservative, phenoxyethanol.
