潔面乳點揀？泡沫、啫喱、卸妝油同 pH 值一次講清：LAGOM、S.NATURE、HYGGEE、Needly、SKIN1004
Share
揀潔面乳先睇三樣：質地（泡沫、啫喱、油）、pH 值同表面活性劑類型，最後先睇你有冇上妝同防曬。美國皮膚科學會（AAD）建議用溫和、不含酒精、唔會磨擦皮膚嘅潔面，用微溫水，每日早晚各一次，流汗後再洗多次。洗完緊繃，通常係太強嘅信號。
Choose a cleanser by three things: texture (foam, gel or oil), pH and surfactant type, then whether you wear makeup and sunscreen. The American Academy of Dermatology recommends a gentle, alcohol-free, non-abrasive cleanser used with lukewarm water twice a day and after sweating. A tight feeling after washing is usually a sign the cleanser is too strong.
點解 pH 值同表面活性劑重要？(Why pH and surfactants matter)
皮膚表面天然偏弱酸性，研究稱為「酸性保護膜」（acid mantle），同屏障功能、角質層完整性同抗菌防禦都有關係（Ali & Yosipovitch, 2013）。所以弱酸性配方通常被視為對屏障較友善嘅選擇。表面活性劑方面，氨基酸系（例如椰油醯甘胺酸鈉、椰油醯谷氨酸鈉）一般被形容為較溫和，會令泡沫綿密但唔會洗得太乾。
Skin's surface is naturally mildly acidic, described in research as the acid mantle, which is tied to barrier function, stratum corneum integrity and antimicrobial defence (Ali & Yosipovitch, 2013). That is why mildly acidic formulas are generally seen as barrier-friendly. On surfactants, amino-acid types (such as sodium cocoyl glycinate or cocoyl glutamate) are usually described as gentler, giving a creamy lather without stripping.

泡沫、啫喱、油：點樣揀 (Foam, gel or oil)
-
有上妝或用防水防曬：先用卸妝油（例如 SKIN1004）溶走底妝同防曬，再用泡沫或啫喱做第二步。產品頁形容佢質地輕盈、易乳化沖洗。
If you wear makeup or water-resistant sunscreen: start with a cleansing oil (such as SKIN1004) to dissolve makeup and sunscreen, then follow with a foam or gel. The product page describes it as light and easy to emulsify and rinse. -
油性、混合肌：泡沫款（LAGOM、S.NATURE）通常洗得較清爽；LAGOM 加咗礦物鹽做溫和物理去角質，唔建議每日洗得太用力。
Oily or combination skin: foam cleansers (LAGOM, S.NATURE) usually feel fresher; LAGOM adds mineral salt for mild physical exfoliation, so do not wash with extra pressure every day. -
乾燥、敏感或易繃緊：揀 HYGGEE 或 Needly 呢類啫喱，質地柔和；HYGGEE 全程無香料，AAD 亦指出無香料產品通常刺激性較低。
Dry, sensitive or easily tight skin: choose a gel like HYGGEE or Needly; HYGGEE is fragrance-free, and the AAD notes fragrance-free products are generally less irritating. -
暗瘡傾向：Needly 含水楊酸，但潔面接觸時間短，唔好當成治療；暗瘡持續請見皮膚科醫生，並可參考 暗瘡護理指南。
Breakout-prone skin: Needly contains salicylic acid, but a cleanser has a short contact time and is not a treatment; see a dermatologist if breakouts persist, and read our acne care guide.
洗面步驟 (How to wash)
按 AAD 建議：用微溫水打濕面部，用指尖塗上潔面乳，唔好用毛巾或海綿擦，唔好用力搓，沖淨後用軟毛巾輕按吸乾。一日洗兩次已經夠，流大汗後再加一次。洗完之後記得上保濕，可以配合 卸妝後護膚 嘅步驟。
Following the AAD: wet your face with lukewarm water, apply the cleanser with fingertips, avoid washcloths and sponges, do not scrub, rinse and pat dry with a soft towel. Twice a day is enough, plus once after heavy sweating. Follow with moisturiser; our post-makeup-removal routine shows how.
避坑提醒 (Common mistakes)
-
以為洗得越乾淨越好。洗完繃緊代表可能過度清潔，可以參考 屏障受損自我檢查。
Believing a squeaky-clean feel is best. A tight feeling can mean over-cleansing; see our barrier self-check. -
只靠 pH 數字揀。pH 只係其中一個因素，表面活性劑類型同你嘅膚況一樣重要。
Choosing by the pH number alone. pH is one factor; surfactant type and your skin condition matter equally. -
早晚都用磨砂或帶去角質成分嘅潔面。可以同 去角質頻率 一齊計。
Using scrubbing or exfoliating cleansers morning and night. Count them toward your exfoliation frequency. -
水太熱。AAD 建議用微溫水，唔係熱水。
Water that is too hot. The AAD recommends lukewarm water, not hot.
總結 (Bottom line)
日常用一支溫和嘅泡沫或啫喱，有上妝先加卸妝油，已經足夠。想控油揀 LAGOM，想提亮揀 S.NATURE，易繃緊揀 HYGGEE，想要 pH 約 6.0、同時有暗瘡傾向揀 Needly，重妝同防曬就加 SKIN1004。
One gentle foam or gel for daily use, plus an oil on makeup days, is plenty. Pick LAGOM for oil control, S.NATURE for brightening, HYGGEE if you get tight easily, Needly for a pH around 6.0 and breakout-prone skin, and add SKIN1004 on heavy makeup and sunscreen days.
