The Purest Solutions Hydration-Infused Smooth Cleansing Balm

It is considered non-comedogenic and vegan-friendly.

This ingredient has a well-established safety record by the CIR Expert Panel for Cosmetic Ingredient Safety.

Synthetic Waxes are straight/branched-chain hydrocarbons with no ester bond or fatty acids. That means there is nothing for the Malassezia yeast to feed on.

This ingredient has been found safe for use in cosmetics and broader PEG family testing shows minimal irritation/sensitization. The molecule's large size also means it isn't expected to penetrate skin to any meaningful degree.

Fungal acne note: This ingredient may not be fungal acne safe due to isostearic acid (C18). Isostearic acid falls into the C11-24 range that Malassezia can feed on.

The reason this ingredient is so effective is because it forms a thin film on the skin that reduces transepidermal water loss (TEWL) while supplying linoleic acid to the stratum corneum to improve barrier strength.

The high linoleic acid content is particularly noteworthy for acne-prone skin.

Research suggests that acne-prone skin tends to be deficient in linoleic acid in sebum. Topical application may help replenish this to support a healthier follicular environment and less comedone-promoting sebum.

One randomized study found sunflower seed oil preserved skin barrier integrity in adult volunteers with and without atopic dermatitis (outperforming olive oil).

This ingredient is well-studied, gentle, and an effective emollient suitable for most skin types.

On fungal acne: This ingredient may not be Fungal acne (Malassezia folliculitis) safe. This is because it contains fatty acids with carbon chain lengths in the C11-C24 range.

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%.

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!

This ingredient is an ester of 2-ethylhexyl alcohol and stearic acid.

Typical concentrations range from 0.1-3%.

This ingredient is mild and non-irritating in nature.

Because it is derived from ricinoleic acid, this ingredient may not be fungal acne safe. Ricinoleic acid is an unsaturated fatty acid that the Malassezia yeast can metabolize.

Typical use levels in formulas range from 2-10%.

The CIR Expert Panel has concluded this ingredient to be safe as a cosmetic ingredient.

Since this ingredient is an ester of oleic acid, it may not be fungal acne safe. Oleic acid is a fatty acid that falls into the C11-24 range that Malassezia can metabolize.

This palmitoleic content is also part of why macademia seed oil absorbs quickly and doesn't leave much of a greasy residue.

It also contains oleic acid, linoleic acid, and phytosterols that can help reduce redness.

In vitro research has shown the oil to have meaningful antioxidant activity, protect fats in the skin from oxidative damage, and slow down the enzyme that breaks down hyaluronic acid.

A 2024 clinical study found it effective at improving skin hydratino and reducing wrinkle appearance when formulated into nanoemulsions.

Because it carries oleic acid (C18) and palmitic acid (C16), this ingredient may not be fungal acne safe. This is because the Malassezia yeast metabolizes in the C11-24 chain length range.

You'll also see this ingredient listed as: Macadamia Integrifolia Seed Oil .

These two oils are identical in composition and M. ternifolia is an older INCI naming convention for the edible macadamia nut while M. integrifolia is the species actually cultivated for oil production. Both names refer to the same oil.

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.

Like other alcohols, this ingredient helps prevent the growth of bacteria. However, its main purpose is to impact a fragrance.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

Studies show the compounds in centella help with:

The combination of all these properties makes centella effective at soothing, hydrating, and protecting the skin.

Other great components of centella include Vitamin A, vitamin C, several B vitamins, and Asiatic Acid.

Fun fact: Centella has been used as a medicine and in food for many centuries. As a medicine, it is used to treat burns, scratches, and wounds.

This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.

Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

In vitro studies have shown that Rosa damascena can scavenge free radicals and reduce melanin overproduction. Research has also found this extract offers some degree of UV absorption but this should not replace your sunscreen.

Other major parts of Rose Oil include citronellol and geraniol. Both of these are known EU allergens and cause contact-allergies.

The downsides of this ingredient outweight the positives.

This dye is commonly used in foods, approved by both the FDA and EFSA.
