Thinksport SPF 50 Clear Zinc Face Sunscreen
Ingredients explained

What-it-does: sunscreen | Irritancy: 0 | Comedogenicity: 1

When it comes to sunscreen agents, Zinc Oxide is pretty much in a league of its own. It's a physical (or inorganic) sunscreen that has a lot in common with fellow inorganic sunscreen Titanium Dioxide (TiO2) but a couple of things make it superior even to TiO2.

If physical sunscreens don't tell you anything, go ahead and read about the basics here. Most of what we wrote about Titanium Dioxide is also true for Zinc Oxide so we will focus here on the differences. 

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

A super common emollient that makes your skin feel nice and smooth. It comes from coconut oil and glycerin, it’s light-textured, clear, odorless and non-greasy. It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type and easy to formulate with. No wonder it’s popular. 

What-it-does: emulsifying

We don't have description for this ingredient yet.

Glycerin - superstar
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • A super common, safe, effective and cheap molecule used for more than 50 years
  • Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
  • Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
  • High-glycerin moisturizers are awesome for treating severely dry skin

What-it-does: emulsion stabilising

We don't have description for this ingredient yet.

What-it-does: emollient

A fast spreading emollient ester (hexyl alcohol + lauric acid) that's used in water in oil emulsions or in water-free formulas. It gives a light skin feel. 

What-it-does: emollient

A helpful emollient ingredient that gives products a light, smooth-skin feeling. You’ll find it mostly in products containing SPF, as, according to several manufacturers, it can increase the water resistance and spreadability of UV filters. With better spreadability, less filters are needed to provide the same SPF, making the formula lighter and nicer to use and with improved water resistance, your protection will last that bit longer in the pool.

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

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. 

What-it-does: emollient, viscosity controlling, emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 1

A chemically modified version of castor oil that results in a solid, waxy material that serves as an emollient and consistency building material.

It also has some unique moisturizing properties as it is both occlusive and humectant.  The former one is common for oils and waxes and it means that it sits on top of the skin hindering water to evaporate out of the top layers. The latter one, the humectant property, is surprising and comes from the unique property of ricinoleic acid (the dominant fatty acid in castor oil)  having an extra water-loving -OH group on its otherwise oil-loving fatty chain. We have some more info about this at castor oil, so if you are interested, read on here.  

Also-called: Epsom salt | What-it-does: viscosity controlling

A helper ingredient that is used as a bulking and viscosity controlling agent. It is also an emulsion stabilizer in water-in-oil emulsions, where water droplets are dispersed in the continuous oil phase and not the other way round.

It can also be used as a heat generating agent in water-less formulas as it has an instant heat-generating chemical reaction with water. 

Tocopherol - goodie
Also-called: Vitamin E | 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

What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

It’s the - sodium form - cousin of the famous NMFhyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here.  The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water.

As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit  "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". 

Also-called: Papaya Fruit Extract

We don't have description for this ingredient yet.

What-it-does: astringent, emollient, perfuming

We don't have description for this ingredient yet.

Also-called: Pink Grapefruit Peel Oil | What-it-does: perfuming

The essential oil coming from the peel of the pink grapefruit. In general, the main component of citrus peel oils is limonene (around 90% for grapefruit peel), a super common fragrant ingredient that makes everything smell nice (but counts as a frequent skin sensitizer). Similar to other essential oils, grapefruit peel has also antibacterial and antifungal acitivity

Other than that, citrus peels contain the problematic compounds called furanocoumarins that make them (mildly) phototoxic. So be careful with grapefruit peel oil, especially if it's in a product for daytime use.  

What-it-does: emulsifying | Irritancy: 0 | Comedogenicity: 0-1

A mainly oil loving molecule that helps water and oil to mix nicely, aka emulsifier. In itself, it can create water-in-oil emulsions (when water droplets are dispersed in oil), but it is used mostly next to water-loving emulsifiers to create nice and smooth oil-in-water creams.  It can also function as a wetting and dispersing agent helping insoluble particles such as color pigments or inorganic sunscreens (zinc/titanium dioxide) to disperse nice and even in liquids.  

Chemically speaking, this molecule is "halfway" between Sorbitan Oleate and Sorbitan Trioleate, meaning that it is also an attachment of sorbitan (a dehydrated sorbitol (sugar) molecule) with the unsaturated fatty acid Oleic Acid, but in a ratio of 2:3 hence the "Sesqui" part in the molecule's name. 

What-it-does: chelating

A chelating agent that helps to preserve cosmetic products by neutralizing the metal ions (especially iron) in the formula (that usually get into there from water). Its special thing is that it also acts as a biostatic and fungistatic agent and remains active even at high pH.

It is often coupled with antimicrobial glycols (such as propanediol) to create a "preservative free preservative system" for cosmetic products.

A clear, light yellow liquid that is used to coat pigments (such as inorganic sunscreen agents or colorants) in cosmetic products.  The coating helps to stabilize pigments in the formulas and also helps them to spread easily and evenly on the skin. 

What-it-does: preservative

A 100% plant derived, natural (Ecocert approved) multi-functional ingredient that has emollient and moisturizing properties, can work as a co-emulsifier (meaning that next to other emulsifiers it can help water and oil to mix)  and even more importantly has a strong antimicrobial activity

Thanks to this last thing, it allows a lower percentage of traditional preservative or it might even be able to completely replace them.
