Ingredients Explained
Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics.
Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity.
Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation.
It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh.
Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated.
This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%.
Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating.
Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism.
Learn more about AllantoinCitrus Aurantium Bergamia Fruit Oil is the oil from the bergamot orange and is primarily used as a fragrance. It has a "fresh" and "bright orange" scent.
The main aroma compounds found in this ingredient are limonene (~27-52%), linalool (~2-22%), and linalyl acetate (~27-40%). These are known EU fragrance allergens.
The term '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.
When used topically, Citrus Aurantium Bergamia Fruit Oil is a photosensitizer due to the furanocoumarin content. Furanocoumarins absorb UV-A and cause phytophotodermatitis; this can look like redness, blistering, and lasting brown pigmentation on sun-exposed skin.
Due to this, this ingredient is capped at 0.4% in leave-on products applied to sun exposed skin.
Many modern formulas used a "furanocoumarin-free" version that sidesteps the phototoxicity issue, but still contains the fragrance allergens.

A study from 2023 found compounds in Equisetum Arvense showed significant anti-inflammatory effects in irritated keratinocytes (the main cell in your outermost layer of skin).
Another study using a cream with horsetail and soybean extract found 80% of participants showed at least a 26% improvement in forehead wrinkles after 8 weeks.
Animal research has shown topical Equisetum Arvense stimulated skin and tissue growth in mice.
The research so far is encouraging, but still in its early days. But it's a lovely supporting ingredient and can be a welcome addition to any routine.
Learn more about Equisetum Arvense ExtractEucalyptol is a fragrance. It can be bad for dry skin.
Lactic Acid is another well-loved alpha hydroxy acid (AHA). It is gentler than glycolic acid but still highly effective.
Its main role is to exfoliate the surface of the skin by loosening the âglueâ that holds dead skin cells together. Shedding those old cells leads to smoother, softer, and more even-toned skin.
Because lactic acid molecules are larger than glycolic acid, they donât penetrate as deeply. This means theyâre less likely to sting or irritate, making it a great choice for beginners or those with sensitive skin.
Like glycolic acid, it can:
Lactic acid also acts as a humectant (like hyaluronic acid). It can draw water into the skin to improve hydration and also plays a role in the skin's natural moisturizing factor (NMF) in the form of sodium lactate.
Studies show it can boost ceramide production to strengthen the skin barrier and even help balance the skinâs microbiome.
To get results, choose products with a pH between 3-4.
Lower strengths (5-12%) focus on surface exfoliation; higher strengths (12% and up) can reach deeper in the dermis (deeper, supportive layer) to improve skin texture and firmness over time.
Though it was originally derived from milk, most modern lactic acid used in skincare is vegan. It is made through non-dairy fermentation to create a bio-identical and stable form suitable for all formulations.
When lactic acid shows up near the end of an ingredient list, it usually means the brand added just a tiny amount to adjust the productâs pH.
Legend has it that Cleopatra used to bathe in sour milk to help reduce wrinkles.
Lactic acid is truly a gentle multitasker: it exfoliates, hydrates, strengthens, and brightens. It's a great ingredient for giving your skin a smooth, glowing, and healthy look without the harshness of stronger acids.

Learn more about Lactic AcidLavandula Angustifolia Oil is more commonly known as lavender essential oil. It is considered a fragrancing ingredient.
Lavender imparts a famous scent. While the smell is lovely, this ingredient and may sensitize skin in topical products. This is because about 85% of the oil is made up of linalool and linalyl acetate.
When exposed to air, these two compounds become strong allergens. This ingredient exhibits cytotoxicity at low concentrations; amounts of 0.25% have been shown to damage skin cells.
A study from Japan found this ingredient caused lavender sensitivity after widespread exposure.
Lavender essential oil has some antimicrobial, antibacterial, and anti-inflammatory properties. However, the cons of this ingredient may outweight the pros.
More research is needed to confirm lavender essential oil's effects when used in aromatherapy.
Lavandula Angustifolia is known as the English Lavender and famous for creating purple fields in Provence, France.

This ingredient is also known as grapefruit or citricidal extract. It has perfuming and astringent properties.
Astringents shrinks tissue by drawing water out of your skin. This leads to a temporary tightening effect in the skin.
We don't have a description for Fucus Serratus Extract yet.
Saccharide Isomerate comes from sugars found in corn. It is a skin hydrator.
The structure of this ingredient can be altered to be more similar to the carbohydrates found in our skin. This ability to mimic our skin gives it hydrating properties.
Specifically, saccharide Isomerate is a humectant. Humectants draw moisture from the air to our skin.
Research shows Saccharide Isomerate to be an effective moisturizer.

This ingredient is also known as dandelion extract. It has skin conditioning properties.
Studies show the leaf, stem, and roots of this plant are rich in antioxidants such as caffeic acid and polysaccharides, which act as humectants to help hydrate the skin.
This ingredient comes form the common thyme plant. It has skin conditioning and perfuming ingredients.
In-vitro studies show strong antioxidant activity due to the high phenolic content of thyme.
Studies also demonstrate it has antimicrobial activity against acne-related bacteria. A 2017 study found this extract exhibited anti-inflammatory effects.
However, this ingredient does have sensitization potential due to its terpene content. Terpenes are among the most common causes of contact dermatitis.
This is kind of a double-edged sword situation where the same compounds that give it antimicrobial power can also irritate reactive skin.
Learn more about Thymus Vulgaris ExtractZingiber Officinale is more commonly known as ginger.
Ginger root has antioxidant, anti-inflammation, and antimicrobial properties.
The antioxidant properties help protect your body from free-radicals. Free-radicals are molecules that may damage your skin cells. As a result, ginger may help slow down signs of aging such as hyperpigmentation and wrinkles.
Studies show ginger inhibits the enzyme that breaks down collagen. It also helps with:
This ingredient has no negative side-effects and is safe to use unless one has a specific allergy to it.
Ginger originates from Southeast Asia but has spread throughout the world. It is now a common spice used in many cultures.
