Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Asiatic Acid is one of the four main actives found in Centella Asiatica. Its headline job is stimulating collagen.
Lab tests on human skin cells show Asiatic Acid tells your skin to make more collagen, the protein that keeps skin firm and bouncy.
It also calms inflammation and acts as an antioxidant so it can help skin heal faster, rebuild itself, and repair a damaged barrier.
And on naming, even though "acid" is in the name, it's nothing like an AHA or BHA exfoliant. It's a gentle firming and soothing ingredient that supports your skin barrier.
Concentration-wise, Asiatic Acid is potent at very low doses and usually shows up as a small fraction of a broader centella extract.
Analyses of centella material put Asiatic Acid reported in the range of 0.2-3% of the extract.
This ingredient is non-sensitizing and guinea pig sensitization testing also found it to be a weak sensitizer. That means the risk of acquiring contact sensitivty is quite low.
Allergic contact dermatitis does exist but is also very rare; documented cases tend to involve prolonged use on broken skin plus co-sensitization to fragrance ingredients.

Research from 2016-2025 supports its role in:
You'll usually find this in concentrations between 0.2-5%.
Learn more about AsiaticosideMadecassic Acid is one of the four star actives in Centella Asiatica. In skincare, it earns its keep as a calming and repairing ingredient.
It works through the same core pathways as the rest of the centella family.
First, it turns down inflammation so it helps with things like redness and general upset skin.
Second, it acts as an antioxidant which means it helps protect skin from daily stress and damage.
And third, it nudges the skin to make more collagen and rebuild its support structure.
That combination is why the whole Centella family is known for calming skin, strengthening the barrier, fading redness, and giving anti-aging benefits.
It's worth being honest about the evidence here; a lot of the strongest data is on the full extract or a Madecassoside/Asiaticoside rather than Madecassic Acid alone. Reviewers also note more long-term clinical trials are needed to confirm the full potential.
Concentration-wise, this ingredient is rarely used pure and usually shows up as part of a standardized centella extract where reported content ranges from 0.02-3.06%.
Finished products typically run somewhere in the 0.1-10% range depending on the format.
In real-world tolerance tests, a repeat-insult patch test on an eye lotion with 0.2% Centella extract showed no irritation or allergic contact dermatitis in 54 subjects. And a mascara with 0.5% Madecassoside caused neither irritation nor sensitization in 109 subjects.
Allergy risk is very low, but not zero. Centella and its constituents are classified as weak contact sensitizers and some rare cases of allergic contact dermatitis exist.
