Bare Republic Bare Republic Coco-Mango Mineral Sunscreen Spray SPF 30

Sunscreens containing bentonite display higher water resistance and stay on the skin for much longer. The sunscreens containing bentonite also show higher potency and UV light absorbtion.

Bentonite is naturally created from volcanic ash and several natural weathering/hydrothermal processes.

A common usage of bentonite is removing excess protein from white wines. Bentonite contains a property of being able to absorb large amounts of protein from aqueous solutions.

Phyllosilicate clay has a structure formed by sheets.

Photostabilizers help stabilize UV-filters and prevents them from degrading quickly.

By the way, the FDA allows products to be labeled "alcohol-free" even when they contain fatty alcohols like this one.

In a formula, it prevents the water and oil phases from separating over time while also contributing to a pleasant, non-greasy slip.

Interestingly, this ingredient can organize into the structures that mimic the skin's own lipid architecture to help support barrier function and reduce transepidermal water loss (TEWL).

The CIR Expert Panel has thoroughly assess the individual fatty alcohols that make up this blend and found no significant toxicity or dermal irritation.

Fungal acne: Research has shown the Malassezia can grow in the presence of fatty alcohols with the chain length between C12-24, making this ingredient not fungal acne safe.

Caprylhydroxamic Acid is often used with natural antimicrobial products as an alternative to preservatives.

In practice, that translates to a long shelf life and a consistently elegant skin feel.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns.

Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.

This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.

This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.

Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).

This ingredient is considered hypoallergenic and non-toxic. Cellulose Gum can be found in cosmetics, food, and other household goods such as paper products.

It plays several roles in a formula:

Typical use levels for this ingredient sit around 1-10% and the Cosmetic Ingredient Review Expert Panel has affirmed safety at concentrations up to 25% in leave-on products.

Multiple assessments have found it to be non-irritating and non-sensitizing to most people.

However, there have been some cases of allergic contact dermatitis in patients with chronically compromised skin barriers.

Cetearyl alcohol has a comedogenic rating of 2 and irritancy rating of 1. Both of these numbers come from the 1989 study that used rabbit ears; a "2" means mildly comedogenic and a "1" means low irritancy.

Here's the catch: rabbit skin is more sensitive than human skin and throws a lot of false positives. A 1996 reappraisal found that ingredients rated 1-2 in the rabbit ear tests are generally safe for humans.

Remember comedogenic ratings are unable to assess the entire formula of a product or how it will react on your skin. Just be sure to patch test if you are unsure about certain ingredients.

This ingredient is not fungal acne safe. Cetearyl alcohol is a fatty alcohol with chain lengths that fall within the range that Malassezia can metabolize.

A 2019 study has also observed Malassezia growth in the presence of this ingredient, confirming it to be not-fungal acne safe.

This ingredient is considered gentle and non-comedogenic. However, it may still be irritating for some.

As an emollient, carrot seed oil creates a thin film on the skin. This film prevents moisture from escaping, keeping your skin hydrated. Carrot seed oil has a soothing effect and can help alleviate inflammation.

As an antioxidant, carrot seed oil may help reduce the signs of aging. Antioxidants are able to neutralize free-radical molecules, or molecules that can damage our skin's cells and DNA.

Emerging studies show the alpha-pinene and carotol content give carrots antibacterial and antifungal properties. However, this is dependent on the amount of each compound. More studies are needed.

Carrot Seed Oil is not carrot oil. Carrot oil is created by mixing parts of the carrot in a carrier oil, such as coconut oil.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Its similarity to our skin's natural oils makes it a great emollient. Emollients help soften and soothe our skin by creating a barrier on top. This barrier helps trap moisture in, keeping skin hydrated.

It is created using either the hydrogenation or transesterification processes on jojoba oil.

Rosmarinic acid has been shown to calm inflammation signaling in skin cells (the same pathways that flare up in conditions like eczema and psoriasis). It also has real antimicrobial and antifungal activity in test-tube studies.

This ingredient is typically used in low concentrations (generally well under 1%) where it acts as a light fragrance + mild skin soother extract.

The main thing to know is that lavender contains two naturally fragrant molecules: Linalool and Linalyl Acetate. Some people's skin does perfectly fine with fragrance while others don't.

Just be sure to patch test if you have reactive skin or known plant allergies.

Linalool and Linalyl Acetate are gentle when fresh but oxidize into compounds that can cause allergic contact dermatitis when exposed to air. Patch-test studies of patients already being investigated for skin allergies found about 5-7% of patients had reactions to oxidized linalool, and 2.8% of patients reacted to oxidized lavender oil.

At its maximum recommended strength of 4%, this ingredient is not likely to make a significant contribution to SPF factor. Polycrylene has a large molecular weight so it's unlikely to penetrate skin.

Although rare, this ingredient can cause contact dermatitis.

Due to regulatory loopholes, you'll be able to find this chemical UV filter in "100% mineral" sunscreens.

Last, the phytochemicals found in apples are strong antioxidants. These antioxidants help with anti-aging as they protect your skin cells against oxidative damage.

As an emollient, raspberry seed oil helps hydrate your skin. Emollients prevent moisture from evaporating by creating a film on top.

This makes it a great choice for spray formulations, serums, and lightweight moisturizers where traditional shea butter would be too heavy.

It's rapidly absorbed on skin and provides an instant moisturizing effect and velvety after-feel.

These conditioning benefits trace back to shea's well-studied bioactive profile; shea is rich in antioxidants like tocopherols and contains stearic and oleic acids that support skin barrier health.

It also contains triterpene alcohols known to reduce inflammation, cinnamic acid esters with some UV-absorbing capacity, and lupeol that protects skin proteins.

Research backs up those triterpenes: a study isolating triterpene acetates and cinnamates from shea fat found all tested compounds showed anti-inflammatory activity in mice.

Fungal acne: Because this is an ethyl ester derived from shea's long-chain fatty acids (primarily stearic C18 and oleic C18), in vitro testing has shown the Malassezia species can grow in the presence of ethyl esters. This ingredient may not be fungal acne safe.

Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.

It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.

This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.

This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.

In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.

Concentrations usually range from 0.1-1% in most leave-on products.

According to perfume manufacturers, this ingredient is almost odorless but has a mild fruity, wine and plum scent. It can be used to mask the scent of other ingredients.

This ingredient can be plant-sourced or synthetic; it can naturally be found in cabbage and white wine.

This ingredient is not known to sensitize or irritate skin (unlike Vanilla Tahitensis). Vanilla tahitensis has shown to irritate skin in low amounts.

Vanillism is the term of contact-dermatitis associated with the vanilla plant. The sap of the vanilla plant triggers skin irritation, swelling, and redness.

Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Antioxidants help stabilize free-radicals by donating extra electrons. Grape seed extract may help reduce the signs of aging.

The antimicrobial properties of grape seed may help treat acne. However, more research is needed to support this claim.

Grape seed has also been found to help absorb UV rays. Grape seed extract should not replace your sunscreen.

The fatty acids of grape seed oil give it emollient properties. Emollients help soothe and soften your skin by creating a film. This film traps moisture within, keeping your skin hydrated.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
