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.
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.
Ribes Nigrum Seed Oil is oil from the seeds of Black Currant. A more common name for this ingredient is Black Currant Seed Oil.
Black Currant Seed Oil contains a high amount of omega-6 and omega-3 fatty acids. It also contains linoleic acid.
Black currant berries contain anthocyanins, an antioxidant. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
Black currant berries also contain Vitamin E and fatty acids. It can help soften the skin.
This is a botanical extract from the rosemary plant (the same one you cook with). In skincare, it mostly works as a skin conditioning agent.
Its activity comes from a handful of polyphenols, carnosic acid, carnosol, and rosmarinic acid. Almost 90% of the antioxidant activity of this ingredient can be attributed to canosol and carnosic acid.
These compounds protect your skin two ways:
1) They fight off free radicals, or the unstable molecules from things like sun and pollution that age and damage skin. 2) They help calm inflammation by switching off the chemical signals that tell skin to get red and irritated.
Lab studies also suggest that rosmarinic acid may help protect collagen and slow sugar-related damage to it.
The Cosmetic Ingredient Review has concluded rosemary-derived ingredients to be safe when formulated to be non-sensitizing.
Rosemary can occasionally cause allergic contact dermatitis (due to carnosol), so be sure to patch test if you have reactive or fragrance-sensitive skin.
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!
