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
Corallina Officinalis Extract is from the red seaweed, Corallina Officinalis. This seaweed is found all over the world but is most common in the rocky shores of Great Britain and Ireland.
Corallina Officinalis Extract contains antioxidant and emollient properties.
Extracted polysaccharides, galactose and xylose, in red algae showed antioxidant activity. Antioxidants help with anti-aging by neutralizing free-radical molecules. Free-radical molecules may damage your skin cells and DNA. Galactose is also a PHA.
Corallina Officinalis is structurally similar to coral due to its high calcium content.

Turmeric contains curcumin, an antioxidant. Antioxidants help neutralize unstable free-radical molecules. Free-radical molecules may damage your skin's cells and DNA. Curcumin may help with anti-aging.
Curcumin also has anti-inflammatory properties and can help soothe skin and reduce irritation. On top of that, curcumin has been shown to help prevent hyperpigmentation from sun damage.
The anti-microbial property of turmeric can make it effective in treating acne. This property has also been shown to help regulate the production of sebum.
Learn more about Curcuma Longa Root ExtractLactic 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 “glue” 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 don’t penetrate as deeply. This means they’re 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 skin’s 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.
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 AcidMelia 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.
Learn more about Melia Azadirachta Flower ExtractMelia Azadirachta Leaf Extract is extract from the neem plant.
The leaves of this tree contain flavonoids and polyphenols. These two compounds are antioxidants, anti-inflammatory, and antibacterial. Further research is needed as to their effects when applied on skin.
We don't have a description for Ocimum Basilicum Flower/Leaf Extract yet.
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.

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.
Learn more about Sodium BenzoateWater. 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. Stay hydrated!
