Precautions for Madecassic Acid: What You Must Know Before Use

Madecassic acid is an ingredient extracted from Centella asiatica and is frequently used in skincare products for soothing care purposes. However, the ingredient itself is not a cure-all, and depending on skin condition and other ingredients used together, some people may experience irritation, so it is good to review a few points before use.

What is madecassic acid?

Madecassic acid is one of the main components of Centella extract and is known to help with skin soothing and conditioning care. It is used as a single ingredient but is also widely used in soothing product lines when formulated together with madecassoside, asiatic acid, and others.

However, since it is an organic acid-type ingredient, it can be perceived differently by individuals depending on the product's acidity (pH) and concentration, and it is worth noting that there is potential for irritation, especially when the skin barrier is thin.

Extra caution is needed in these cases

When the skin barrier is temporarily compromised, such as immediately after laser or lifting procedures or after peeling, it is recommended to start with gentle soothing care without irritation rather than applying high-concentration madecassic acid products right away.

Using high concentrations of madecassic acid simultaneously with exfoliating ingredients like retinol, AHA, or BHA can add to irritation during sensitive skin periods, so it is safer to divide application times or set priorities and apply them in stages.

When using a new product for the first time, it helps to apply a small amount to the inner arm or behind the ear to check for any reaction before using it on the entire face.

Adjust your approach by stage

When skin is irritated immediately after a procedure (1-3 days post-treatment or after intensive exfoliation), it is best to use products containing madecassoside minimally with a focus on low-irritation and soothing care.

From around day 4 to one week after irritation begins to subside, skin tightness and dryness often remain, so it is natural to shift to care focused on deep hydration and skin texture refinement rather than soothing during this period.

Once skin condition stabilizes, it is often fine to reincorporate products containing madecassoside into your regular routine, but it remains important to observe and adjust based on individual skin response.

Suggested home care routine by stage

Stage 1 (immediately after irritation~3 days): After cleansing, lightly refine skin texture with a low-irritation soothing product, and applying it in thin layers multiple times is less burdensome than applying it thickly in one layer.

Stage 2 (4 days~1 week): It helps to supplement a hydrating cream on areas experiencing skin tightness and dryness to refine skin texture.

Stage 3 (after 1 week): Resume using soothing products containing madecassoside, but it is recommended to space out exfoliating ingredients and monitor skin response when using them together.

Post-procedure recovery depends on home care

During periods when skin becomes sensitive, such as immediately after a procedure, a 2-STEP approach designed for post-procedure management can be more helpful than madecassoside treatment alone. During the initial phase when irritation is concentrated, prioritize redness calming and barrier care with an ultra sera-rich cream containing a complex of 5 ceramides and panthenol, and then continue with deep hydration and skin texture care using a high-concentration panthenol hydro re-boosting cream during the recovery phase when skin tightness remains.
