Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
Humectant, drawing moisture into the skin
Emollient, helping to soften skin
Solvent, dispersing and stabilizing formulas
Preservative booster, enhancing the antimicrobial activity of other preservatives
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Curcuma Longa Root Extract comes from the rhizome (underground stem) of the turmeric plant.
While the official EU Cosing Database lists this ingredient as a fragrance, it actually does more than give products a scent.
This ingredient contains a group of yellow pigments called curcuminoids (mostly curcumin) that give it genuine antioxidant and anti-inflammatory activity in skin.
Reviews of topical clinical studies have found turmeric/curcumin to be generally well-tolerated and useful across conditions like eczema and mild inflammation.
One thing working in its favor is that curcumin barely penetrates; in lab skin-permeation testing, the curcuminoids mostly stayed in the outermost layer of skin. This is a good thing because its soothing and antioxidant activity is a surface-level job anyway.
At this time, industry data shows there's no single "correct" cosmetic percentage. It's used across a wide range depending on the product and varies from tiny fractions of a percent up to a few percent.
Allergy-wise, curcumin is a documented (but uncommon) contact allergen. It can also cross react with related plants, so anyone with a turmeric/ginger/cinnamon allergy or reactive skin should patch test first.
Dextrin is a starch-derived polysaccharide. It's made by partially breaking down corn, potato, or other plant starches.
Think of it as "half-processed" starch; it's less complex than the original but not fully broken down into sugar like maltodextrin.
In cosmetics, it mainly functions as a bulking agent, viscosity controller, binder, and absorbent. It helps thicken products, stabilize powders, and get certain textures a less "wet" feel.
This ingredient has a pretty solid safety profile; it's recognized as a safe food additive and its large molecular size means it doesn't meaningfully penetrate skin.
Human repeat insult patch tests using a rinse-off facial product containing 42.69% dextrin found no skin irritation or sensitization in 54 subjects.
Typical real-world usage is much lower: usually under 1% as a texture modifier and up to 40% in masks (rinse off products use less).
Dipropylene Glycol is a synthetically created humectant, stabilizer, and solvent.
This ingredient helps:
Dipropylene glycol is technically an alcohol, but it belongs to the glycol family (often considered part of the ‘good’ alcohols). This means it is hydrating and gentle on skin unlike drying solvent alcohols like denatured alcohol.
As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.
Studies show Dipropylene Glycol is considered safe to use in skincare.
Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:
The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.
Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.
Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Melia Azadirachta Flower Extract is from the Neem tree. Neem trees originate from India.
Melia Azadirachta Flower Extract contains antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
The flowers of this tree are lilac colored.
This ingredient is also known as neem leaf extract. It contains natural compounds like nimbidin, quercetin, and other polyphenols that give it antibacterial, antifungal, and anti-inflammatory activity.
Lab studies have shown neem leaf extract can inhibit acne-related bacteria and help calm skin. Animal studies on wound gels using 1-3% neem leaf extract found it sped up healing without causing irritation.
A wound-healing study testing gels with the extract at 1%, 2%, and 3% concentrations and found none of them irritated the skin.
Most commercial products also use it in a similar low range (typically under 5%).
Allergy-wise, there are some case reports on neem oil causing allergic contact dermatitis so people with plant/botanical sensitivities may want to patch test first.
Ocimum Sanctum Leaf Extract comes from the Holy Basil plant. Holy Basil is native to India.
Holy Basil is rich in antioxidants due to its high romarinic acid, ferulic acid, and rutin content. This gives it skin brightening and soothing properties.
While Holy Basil has many claims to help fight acne, more research is needed.
One thing to note is the presence of tannins; tannins are naturally found in nature. However, this compound may be skin-sensitizing.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
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!
