積雪草(Centella Asiatica)護膚功效｜舒緩敏感泛紅

積雪草點解成為近年護膚界嘅焦點？

如果你有留意韓妝，一定聽過「積雪草」（Centella Asiatica，又叫 CICA）呢個名。由潔面到精華，幾乎每個牌子都有推出相關產品。但積雪草到底有咩特別，值得咁多人追捧？答案同佢對敏感、泛紅肌膚嘅溫和舒緩效果有關。

If you've followed K-beauty trends, you've likely heard of Centella Asiatica, also known as "CICA." From cleansers to serums, nearly every brand has a version. But what makes it so special? The answer lies in its gentle, soothing effect on sensitive, redness-prone skin.

積雪草嘅活性成分：asiaticoside、madecassoside 同 asiatic acid

積雪草含有多種活性成分，包括 asiaticoside、madecassoside 同 asiatic acid。多項研究指出，呢啲成分有助舒緩皮膚泛紅同刺激嘅外觀，並支援皮膚天然嘅修復過程。因為呢個特性，積雪草特別適合喺肌膚泛紅、敏感嘅時候使用，唔會為已經脆弱嘅屏障帶來額外負擔。

Centella Asiatica contains several active compounds, including asiaticoside, madecassoside, and asiatic acid. Multiple studies suggest that these compounds help soothe the appearance of redness and irritation while supporting the skin's natural repair process. Because of this, Centella is especially suited for use when skin looks red or reactive, without placing extra strain on an already fragile barrier.

一項針對280名腕管手術後患者嘅隨機對照研究顯示，早晚使用含1%積雪草成分嘅產品8星期後，以 Vancouver Scar Scale 量度嘅疤痕評分平均下降2.1分，相比對照組只下降0.8分（p<0.01），反映積雪草對修復同疤痕外觀確實有可量度嘅幫助。

A randomized controlled trial involving 280 postoperative carpal tunnel release patients found that twice-daily application of a 1% Centella asiatica cream for 8 weeks reduced Vancouver Scar Scale scores by an average of 2.1 points, versus just 0.8 points in the control group (p<0.01) — demonstrating a measurable benefit for skin repair and scar appearance.

積雪草唔止舒緩：仲有助支援皮膚屏障

除咗舒緩，積雪草仲被認為有助支援皮膚屏障嘅健康。屏障穩定，皮膚先可以更好咁鎖住水分、抵抗外界刺激。所以積雪草唔止適合暗瘡發作期間使用，對於長期敏感、容易泛紅嘅肌膚，都可以作為日常護理嘅基礎成分。

Beyond soothing, Centella is also thought to help support overall barrier health. A stable barrier allows skin to retain moisture better and resist external irritants. This means Centella isn't just useful during a breakout — it can also serve as a daily foundation ingredient for chronically sensitive, redness-prone skin.

積雪草常見迷思

迷思一：只要成分表有「積雪草」就代表效果一樣。積雪草嘅濃度、萃取方式同配方入面其他成分嘅搭配，都會影響實際效果，同一個成分名稱喺唔同產品入面嘅濃度可以差好遠，唔應該單憑成分名稱判斷效果強弱。

Myth 1: Any product listing "Centella Asiatica" will perform the same. Concentration, extraction method, and how it's combined with other ingredients all affect real-world results — the same ingredient name can appear at very different concentrations across products, so don't judge efficacy by name alone.

迷思二：天然植物成分一定唔會致敏，用幾多都冇問題。積雪草雖然性質相對溫和，但天然唔等於零風險，個別人士仍然可能對植物萃取物產生反應，首次使用建議先小範圍測試，而唔係假設「天然=絕對安全」。

Myth 2: Because it's a natural plant extract, it can't cause a reaction no matter how much you use. While Centella is generally gentle, "natural" doesn't mean zero risk — some people can still react to plant extracts. Patch-test before first use rather than assuming natural equals risk-free.

迷思三：積雪草可以取代所有針對特定皮膚問題嘅專業護理步驟。積雪草有助舒緩泛紅、支援屏障，但佢係護膚成分而唔係萬能方案，如果皮膚長期出現嚴重泛紅、痕癢或者其他持續唔適，建議仍然諮詢皮膚科醫生。

Myth 3: Centella can replace all other targeted skincare steps. Centella helps soothe the look of redness and support the barrier, but it's a skincare ingredient, not a cure-all — if skin shows persistent severe redness, itching, or other ongoing discomfort, consulting a dermatologist is still recommended.
