Essence Lip Care Cocoa Lip Butter

In vitro research found an increase in skin hydration by 58% and a decrease in TEWL by 37.8% after 24 hours of applying this ingredient (pretty impressive for a single ingredient!).

Besides hydration, shea butter also contains triterpenes that have anti-inflammatory potential. In particule, lupeol cinnamate has shown the highest anti-inflammatory activity in vivo.

Shea butter also contains vitamins A and E which may contribute to antioxidant activity.

While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.

This ingredient may not be fungal acne safe because its fatty acids fall within the C11-C24 range that the Malassezia yeast can metabolize.

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.

Cacao seed butter contains antioxidants known as polyphenols. Antioxidants help fight free-radical molecules by stabilizing them. Unstable free-radicals may cause damage to your skin cells. Antioxidants may help with anti-aging.

Theobroma Cacao Seed Butter can be bad for acne prone skin.

In pressed powder cosmetics, it double as a compacting agent.

This ingredient can be synthetically created or plant-derived. Safety-wise, it has a solid track record.

One thing to flag for fungal acne: since this ingredient is the monoester of behenic acid (C22), it falls within the C11-24 range that Malassezia can metabolize.

This ingredient is often used to enhance the texture of products. The fatty acid properties also help hydrate the skin.

Because of its structure, it also acts as a mild skin conditioning emollient that helps soften skin while preventing moisture loss.

Safety studies show it to be safe and non-irritation in clinical tests. It's typically used in concentrations up to 5%.

Since its an ester of a C18 fatty acid, it falls into the C11-24 range that Malassezia can potentially feed on. This makes it not fungal-acne safe.

This ingredient is typically used in concentrations between 1-10%. Studies have found it to be non-sensitizing, non-phototoxic, and non-photoallergenic.

A close cousin of this ingredient is Glyceryl Stearate SE ("self-emulsifying"). This just has a small amount of sodium or potassium stearate added so it can emulsify without a co-emulsifier.

Since this ingredient is an ester of a C18 fatty acid, it may not be fungal acne safe. The Malassezia yeast can potentially metabolize within the C11-C24 range.

Fun fact: The human body also creates Glyceryl Stearate naturally.

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

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.

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.

Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.

As you may know, regular vitamin C is notorious for breaking down when exposed to sunlight and air. Ascorbyl Palmitate is more stable and degrades at a slower rate.

Research on whether it converts efficiently into active vitamin C once it's applied on your skin is still limited.

Some in-vitro studies suggest it may support collagen production, but it is not considered one of the stronger vitamin C derivatives, like:

Due to the palmitic acid base, this ingredient may not be fungal acne safe. Comedogenic studies have also shown this ingredient to have a rating of 2.

It's also worth keeping in mind that comedogenic and irritancy ratings are tested on individual ingredients, not finished formulas. The final product's formulation, concentration, and other ingredients all play a role in how something actually behaves on your skin.

Research highlights its role in antioxidant activity, anti-inflammatory effects, skin barrier protection, and wound healing support.

In vivo research has shown that transepidermal water loss (TEWL) caused by irritant exposure can be reverse with squalene supplementation (pointing to barrier recovery support).

Its antioxidant activity is backed by ex vivo and cell-based evidence showing it can scavenge free radicals but large-scale human clinical trials isolating this effect remain limited.

One study found squalene regulated proinflammatory behavior in ways relevant to wound healing, and in vitro fibroblast studies also shows it stimulates cell migration which is a key step in skin repair.

There's just one nuance to know about this ingredient:

Squalene is particularly vulnerable to oxidation; it breaks down from UV exposure 10x faster than the other lipids on your skin's surface. The byproducts of that breakdown can clog pores and trigger inflammation, potentially worsening acne.

This is why squalene is often hydrogenated into its stable counterpart: squalane (with an "a"). Most great formulations will have alreadu kept this in mind.

Squalene has shown no significant clinical evidence of sensitization and is a great hydrating ingredient.

Here is the official definition from the The International Cosmetic Ingredient Dictionary and Handbook:

“Aroma is a term for ingredient labeling used to identify that a product contains a material or combination of materials normally added to a cosmetic to produce or to mask a particular flavor.”

INCI shows the only purpose of aroma to be "flavouring".

However, due to regulation differences, some companies may use aroma in place of parfum.

In Canada, this ingredient only has to be listed in concentrations above 1%.
