No. 2 Cica Ceramide Repair Cream

Most ceramide products use trace concentrations to rely on name recognition rather than efficacy. When Numbuzin reformulated No. 2 cream in 2022 and disclosed a 10,000 ppm ceramide NP concentration, they showed their math.

That 10,000 ppm figure equals 1% ceramide NP. Ceramides do not work on a more-is-better scale. The supporting cast matters more. The skin’s intercellular lipid matrix uses a roughly 3:1:1 ratio of ceramides, cholesterol, and free fatty acids. Disrupting this ratio creates an expensive moisturizer. Replicating it achieves genuine barrier repair. Numbuzin’s formula includes cholesterol and phytosphingosine alongside the ceramide NP—the three components dermatological research identifies as critical to mimic the skin’s natural lipid structure. This uses the same formulation approach as prescription-adjacent barrier repair products that cost significantly more.

The centella complex is notable because Numbuzin did not take the easy route. Most cica products use generic centella asiatica extract. This formula uses four isolated active compounds: madecassoside, asiaticoside, madecassic acid, and asiatic acid. Each has a different mechanism—madecassoside provides anti-inflammatory action, asiaticoside stimulates collagen synthesis, and the two acids aid wound healing and antioxidant defense. Independent testing is required to verify if these concentrations are optimized, but including all four signals a formulator who understands centella’s pharmacology.

In the jar, the cream looks thick, opaque, and balm-like. The texture changes on contact. It melts with the warmth of your hands, turning from a dense cream into a lightweight formula that absorbs within thirty seconds. It leaves no sticky residue, no heavy film, and no sense of sitting on the surface. Shea butter is the third ingredient and provides the initial thickness, but the silicone and emulsifier system ensures it sinks in. This texture explains why Korean formulation chemistry has a devoted following.

The soothing effect is noticeable at the first application. If your skin is irritated from over-exfoliation, retinoid irritation, wind-burned winter dryness, or a sensitive skin barrier, this cream works. The combination of bisabolol (a chamomile-derived anti-inflammatory), the centella complex, and beta-glucan creates a multi-pathway calming system that addresses redness and reactivity. Users who use this after retinol or chemical exfoliant nights report it buffers irritation without neutralizing treatment benefits.

Niacinamide is on the ingredient list but requires expectation management. At approximately 1%, it is below the 2-5% range where most studies show significant brightening or oil-control benefits. In this formula, niacinamide likely supports the skin by upregulating its own ceramide production, which complements the ceramide NP. If you want standalone niacinamide benefits, this is not the product.

Packaging

The packaging has limitations. Jar packaging exposes the product to air and fingers, which affects ingredient stability. Ceramides and centella actives are reasonably stable, but an airless pump would better preserve the formula over the 12-month use period. The 60 mL size is small for a cream used twice daily; you will likely finish it in two to three months, which affects the value.

Common Complaints

Some botanical extracts further down the list—fig fruit extract, kelp extract, and amaranthus seed extract—act more like a K-beauty ingredient flex than functional additions. They are not harmful, but their concentrations are likely too low to affect performance. The cream works because of its ceramide-cholesterol-phytosphingosine backbone and its centella complex, not because of trace amounts of eclipta prostrata leaf.

Conflicts With

Alcohol (denatured) appears near the end of the ingredient list. Its position suggests a concentration well below 1%, likely acting as a solvent for a botanical extract rather than a drying agent. At this level, it is not a concern for most skin types.

Best for

At roughly $20 for 60 mL, the value is strong. You get a barrier repair formula built on science—the ceramide-cholesterol-fatty acid trio, a multi-compound centella complex, dual-weight hyaluronic acid, and shea butter—at a price lower than many competitors with less sophisticated formulations. Numbuzin is an emerging brand without decades of clinical track record, but the formulation of this product shows an understanding of barrier science rather than just ingredient list padding.
