Ingredients Explained
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 “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.
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 product’s 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.

We don't have a description for Boswellia Serrata Resin Extract yet.
This ingredient is the sterol fraction pulled out of rapeseed (or field mustard) oil. It's the waxy, cholesterol-like part of the oil.
That cholesterol-like part matters because the molecules are structurally close cousins of the cholesterol your own skin makes.
Cholesterol is one of the three lipids (along with ceramides and fatty acids) that hold your skin barrier together. So the plant sterols (like this one) do the same job: they integrate into the barrier and mimic the skin's natural lipids, which helps it hold onto water.
There's some decent evidence too:
A tape stripping study found skin treated with a phyosterol formulation recovered barrier function noticeably faster than skin treated with the vehicle alone.
Phytosterols also show anti-inflammatory activity which is why they appear often in soothing and anti-aging creams.
Usage concentrations vary according to industry survey data; leave-on products go up to 7% and rinse-off products up to 0.13%.
Actual face products usually use lower amounts (0.1-2%), partly because sterols are waxy and don't dissolve easily.
A human repeat insult patch test of 100% pure sterols in 50 subjects produced no irritation/sensitization, and guinea pig maximization testing was also negative. The CIR Expert Panel has also concluded the phytosterol ingredient group is safe at current use concentrations.
Fungal acne note: Sterols are not fatty acids and the yeast makes its own sterols anyway, so this ingredient doesn't feed it (it is fungal acne safe).
