Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Helianthus Annuus Seed Oil is a plant oil derived from the seeds of a sunflower.

It is rich in fatty acids, primarily linoleic acid and oleic acid. This gives it emollient and skin conditioning properties.

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.

This ingredient is also known as black seed oil or black cumin. It has emollient, skin conditioning, and perfuming properties.

It is rich in linoleic and oleic acids, making it a great skin hydrator or emollient. Other compounds found in black seed oil include thymoquinone, sterols, and various terpenes; these compounds give it antioxidant, anti-inflammatory, and antimicrobial properties.

Studies show thymoquinone helps reduce oxidative stress and dampens the inflammatory pathways. Combining this with the oils makes this ingredient great for barrier repair and moisturization.

Other studies have found this ingredient to have antimicrobial activity against several acne-causing bacteria.

Punica Granatum Seed Oil is created from the seeds of the pomegranate. Pomegranate seed oil helps hydrate the skin, is anti-inflammatory, and contains antioxidants.

Pomegranates are rich in fatty acids, including an unsaturated fatty acid by the name of Punicic acid. Other components of pomegranates include Vitamin E, Vitamin C, and bioactive lipids such as phytosterols, phospholipids, and triterpenes. Punicic acid helps soothe inflammation.

As an emollient, pomegranate oil creates a thin film on the skin. This film helps prevent moisture loss, keeping your skin hydrated.

Rosa Canina Fruit Oil is a non-fragrant plant oil that has earned its skincare reputation through chemistry.

It's dominated by fatty acids like linoleic acid (~35-55%), alpha-linolenic acid (~17-27%), and oleic acid (~14-22%). This is the exact profile that supports skin barrier, locks in hydration, and calms inflammation.

A 2024 review found evidence for the Rosa canina species supports its use for scarring, hyperpigmentation, wrinkles, and atopic dermatitis; this was mostly credited to its vitamin C content and fatty acid composition as the primary active mechanisms.

You might see this ingredient marketed as a "natural retinol". Some rosehip seed oils contains traces of all-trans-retinoic acid but these trace amounts are far below biologically active levels.

The Cosmetic Ingredient Review Panel has deemed this ingredient safe and it's well-tolerated.

Fungal acne: The fatty acids of this oil fall into the C11-24 range that Malassezia yeast can metabolize, so this ingredient may not be fungal acne safe.

Tetrahexyldecyl Ascorbate (THD) is a stable and oil-soluble form of Vitamin C.

THD is special in that it has the ability to travel deeper into skin than traditional ascorbic acid while maintaining the same skin benefits (double win!).

Because it’s oil-soluble, THD dives deep into your skin’s fatty layers (think ceramides and cholesterol) to fight off the kind of free radicals that mess with your skin barrier. This makes it a great pair with water-based vitamin C (ascorbic acid) that mainly works on the surface.

Even at just 0.1%, THD is already showing great antioxidant activity. When used up to 2%, it helps keep your skin happy and calm, especially when it’s stressed from pollution or sun.

Want to fade dark spots or tackle hyperpigmentation? You’ll want 5% or more. Pairing it with brightening buddies like niacinamide or licorice root gives even better results. One study even used 30% THD with other brighteners and saw real results on stubborn discoloration, even in melasma-prone skin.

A note on THD: It’s has a slightly silky, oily texture and usually shows up colorless or pale yellow (though the exact shade can vary by supplier).

While you can sneak it into water-based formulas, it really shines when paired with silicones or oils, which help your skin soak it up better.

THD is pretty stable, but it’s still vulnerable to degradation like ascorbic acid. Too much light or heat (above 113°F / 45°C) can break it down over time. Go for dark and opaque packaging that keeps it safe and shady!

Tocopheryl Acetate is a stable, shelf-friendly form of vitamin E.

Formulators love it because plain vitamin E oxidizes quickly once it hits air. This acetate version stays stable and resists going off, helping to extend a product's shelf life.

It's actually inactive on its own and works like a slow-release "storage" form; the enzymes in your skin called esterases gradually convert it into active vitamin E over time.

One in vivo study showed 5% of the acetate in the living layer of the epidermis converted to vitamin E after 5 days of application. This study also found the skin gained protection against UV damage even though the conversion was slow and small.

Once converted, vitamin E acts as a skin's main fat-soluble antioxidant that fights free radicals to protect skin from damage.

Topical vitamin E generally boosts the skin's photoprotection, and it reduced UV-damage in animal models.

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.

Overall, it has a pretty solid safety profile and has been found to be non-irritating and non-comedogenic. Allergic reactions may happen but stay rare due to how widely the ingredient gets used.

The concentration will vary depending on the formula; industry data shows 0.1% in baby lotions, 3% in lipsticks, and 5% in foot powders. You can also find this ingredient at 100% in a pure vitamin E oil.

Most leave-on skincare keeps it at the lower end, often between 0.5-1%.
