THE LAB by blanc doux 低分子玻尿酸系列點用？爽膚水、精華、安瓶、面霜次序同選擇指南

THE LAB by blanc doux 呢個系列嘅賣點係「低分子（Oligo）玻尿酸」：分子細，比較容易進入角質層而唔係停留喺表面。整套次序可以咁排：化妝水 → 透亮精華 → 保濕安瓶 → 鎮靜面霜；如果只買一至兩件，按你最大嘅問題揀就得。

The THE LAB by blanc doux range is built around low-molecular-weight (oligo) hyaluronic acid, whose small molecules are more likely to enter the stratum corneum rather than sit on the surface. A full order is toner, glow serum, hydrating ampoule, then calming cream; if you only buy one or two pieces, choose by your biggest concern.

點解玻尿酸分子大小重要？(Why molecular size matters)

2016 年一項用拉曼光譜追蹤嘅研究（Essendoubi 等人，Skin Research and Technology）比較咗不同分子量玻尿酸喺皮膚入面嘅滲透：低分子量（20 至 300 kDa）可以穿過角質層，而高分子量（1,000 至 1,400 kDa）就穿唔過。呢個係實驗室層面嘅觀察，並唔等於產品喺面上嘅效果；不過係解釋點解品牌會特登強調分子大小。

A 2016 study using Raman spectroscopy (Essendoubi et al., Skin Research and Technology) compared hyaluronic acid of different molecular weights in skin: low molecular weight (20 to 300 kDa) passed through the stratum corneum, while high molecular weight (1,000 to 1,400 kDa) did not. This is a laboratory observation, not a promise of on-face results, but it explains why the brand highlights molecular size.

整套次序點排 (Layering order)

  • 步驟 1：化妝水。潔面後用，打底補水。
    Step 1: Toner. Use after cleansing as a hydrating base.
  • 步驟 2：透亮精華（只喺需要時）。因為含 PHA，建議由隔晚用開始，同其他酸類唔好同晚疊用，詳見 去角質頻率指南。
    Step 2: Glow serum (only when needed). It contains PHA, so start every other night and avoid stacking with other acids; see our exfoliation frequency guide.
  • 步驟 3：保濕安瓶。凝膠質地、吸收快，之後疊搽其他精華都冇問題。
    Step 3: Hydrating ampoule. A fast-absorbing gel that layers well under other serums.
  • 步驟 4：鎮靜面霜。鎖水同舒緩，晚間尤其適合；詳見 冬季保濕疊用。
    Step 4: Calming cream. Seals in moisture and soothes, especially at night; see our winter moisture layering guide.

只想買一兩件？按需要揀 (If you only want one or two)

  • 最基本補水：化妝水＋面霜。
    Basic hydration: toner plus cream.
  • 乾燥敏感：安瓶＋面霜，可以對照 敏感肌保濕。
    Dry and sensitive: ampoule plus cream; compare with our sensitive-skin moisturiser guide.
  • 暗沉為主：透亮精華＋化妝水，日間記得 防曬。
    Mainly dullness: glow serum plus toner, with sunscreen in the daytime.

避坑提醒 (Common mistakes)

  • 以為玻尿酸濃度越高越好。ppm 數字唔等於效果，仲要睇質地、搭配同你嘅皮膚狀態。
    Assuming higher concentration is always better. The ppm figure does not equal results; texture, pairing and your skin condition matter too.
  • 喺極乾環境完全唔鎖水。玻尿酸係保濕成分，空調房或乾燥天氣之後要用面霜鎖住，詳見 辦公室冷氣乾燥。
    Not sealing it in during very dry weather. Hyaluronic acid is a humectant; follow with a cream in air-conditioned or dry conditions, as in our office AC dryness guide.
  • 一次加齊整個系列又同其他活性成分疊用。逐件加入，睇皮膚反應。
    Adding the whole range plus other actives at once. Add one piece at a time and watch your skin.
  • 忘記 patch test。新產品先做耳後測試；皮膚有持續不適請諮詢專業意見。
    Skipping a patch test. Test new products behind the ear; seek professional advice if discomfort persists.

總結 (Bottom line)

呢個系列最大優點係邏輯清晰：化妝水打底、精華針對暗沉、安瓶專攻補水、面霜負責鎮靜。想入手可以由 玻尿酸保濕精華液 或 鎮靜+面霜 開始。更多玻尿酸入門可睇 玻尿酸保濕指南。

The range's strength is its clear logic: toner as a base, serum for dullness, ampoule for hydration, cream for calming. A good place to start is the hydrating ampoule or the calming+ cream. For more basics, read our hyaluronic acid hydration guide.

常見問題 FAQ

  • Q: 低分子玻尿酸同普通玻尿酸有咩分別？
    A: 低分子玻尿酸分子較細。2016 年一項研究顯示低分子量玻尿酸可以穿過角質層，高分子量就唔得；但實際效果因產品配方同個人皮膚而異。
    Q: What is the difference between low-molecular and regular hyaluronic acid? A: Low-molecular-weight hyaluronic acid has smaller molecules. A 2016 study showed it passes through the stratum corneum while high-molecular-weight does not, but real-world results depend on formula and individual skin.
  • Q: 透亮精華可以日日用嗎？
    A: 精華含 PHA，建議由隔晚開始，視乎皮膚反應再調整，並避免同其他酸類同晚疊用。
    Q: Can I use the glow serum every day? A: It contains PHA, so begin every other night, adjust according to your skin and avoid stacking with other acids.
  • Q: 敏感肌適合用呢個系列嗎？
    A: 安瓶產品頁形容無人工香料同色素，面霜經臨床測試刺激度；但個人反應不同，仍建議 patch test。
    Q: Is the range suitable for sensitive skin? A: The ampoule page describes it as free of artificial fragrance and colour, and the cream as clinically tested for irritation, but individual reactions vary, so patch test.
  • Q: 一定要用齊四件嗎？
    A: 唔需要。按最需要嘅功能揀一至兩件已經足夠，再慢慢加。
    Q: Do I need all four? A: No. One or two pieces matching your main need is enough; add more gradually.
