Skinfood Egg White Perfect Pore Cleansing Oil Versus Skinfood Black Sugar Perfect Cleansing Oil

One thing worth noting: a controlled study found this ingredient applied under occlusion to acne-prone subjects increased microcomedones. Just keep in mind this was under occlusive conditions and don't reflect how most products are used day-to-day.

For most people, this is a well-tolerated and lightweight ingredient.

This ingredient may not be fungal acne safe because it is an ester of palmitic acid, a C16 fatty acid that falls within 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.

Squalene is also naturally present in olive oil and exhibits moisturizing and antioxidant properties.

The polyphenols in olive oil also show anti-aging promise; one clinical study found a measurable improvement in skin appearance after 30 days of topical serum use.

Just be aware that applying olive oil directly to skin can weaken the barrier and cause redness. One study with volunteers found even people without sensitive skin experienced a significant reduction in stratum corneum integrity and induced mild erythema.

It's best to use this ingredient as part of a carefully crafted formula (instead of putting it on skin directly from the bottle).

Because it has a 2-3 on the comedogenic scale, it is a moderate risk for acne-prone skin. However, the overall formulation of a product matters more than a few ingredients with comedogenic ratings.

This ingredient may not be fungal acne safe because of the oleic and palmitic acid content. These fall within the C11-24 fatty acid range that the Malassezia yeast can metabolize to grow.

Overall, olive oil is a well-studied and nourishing skincare ingredient.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

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.

It's a well-vetted ingredient for safety and does not penetrate into skin due to its large molecule size.

Because it's a long-chain fatty acid ester, this ingredient may not be fungal acne or Malassezia safe.

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!
