product detail
VA Liposome (Liposome-Encapsulated Vitamin A) redefines how Vitamin A works in skincare by leveraging liposomal delivery technology. Unlike conventional Vitamin A products (retinol serums, retinyl ester creams) where active molecules are exposed to air, light, and skin’s harsh surface— leading to oxidation, irritation, and shallow absorption— VA Liposome encases Vitamin A (often retinol or retinyl palmitate) in tiny, spherical liposomes. These liposomes are made of phospholipids (the same building blocks as skin’s natural lipid barrier), creating a protective “shell” that shields Vitamin A while enabling targeted, deep penetration.
This design makes VA Liposome ultra-stable: it retains 90% of its potency for 8+ months in standard packaging (vs. 3–4 months for unencapsulated retinol) and resists degradation from heat or pH changes (compatible with pH 5.0–7.0, ideal for serums, night creams, and even lightweight lotions). As an over-the-counter (OTC) ingredient, it’s safe for all skin types— including rosacea-prone, post-treatment, or dry-sensitive skin— with concentrations ranging from 0.3% to 1.0% (adjustable for beginners to advanced users). It also pairs seamlessly with hyaluronic acid, niacinamide, and vitamin C, making it a versatile addition to any anti-aging routine.
Key Benefits
- Gentle Anti-Aging (No Irritation): The liposomal shell acts as a buffer, preventing direct contact between active Vitamin A and sensitive epidermal cells. Clinical studies show 90% of users experience no redness, peeling, or stinging— even with nightly use— compared to 65% of irritation reports with unencapsulated retinol. It’s the first VA option safe for sensitive skin seeking wrinkle reduction.
- Deep Dermal Penetration: Liposomes mimic skin’s lipid barrier, allowing them to “fuse” with the stratum corneum and deliver Vitamin A directly to the dermis (where collagen production occurs). Unlike unencapsulated VA (which only acts on the epidermis), this deep reach boosts collagen synthesis by 25% after 8 weeks, targeting fine lines and sagging at the root.
- Sustained Active Release: Liposomes don’t burst immediately— they gradually break down over 12+ hours, releasing Vitamin A in a steady stream. This avoids the “peak irritation” of traditional VA (where high concentrations flood skin at once) and maintains consistent active levels, leading to 30% more visible wrinkle reduction over 12 weeks vs. fast-release retinol.
- Superior Stability: The liposomal shell blocks oxygen, light, and heat— the main causes of VA oxidation. Unencapsulated retinol loses 40% of potency in 1 month of light exposure; VA Liposome retains 85% potency under the same conditions. It can even be used in daytime products (when paired with SPF 30+), a first for most VA derivatives.
- Barrier Repair & Hydration: Beyond anti-aging, the phospholipid liposomes themselves nourish the skin barrier. They replenish ceramides and fatty acids, reducing transepidermal water loss (TEWL) by 22% in 4 weeks— fixing dryness often caused by harsh anti-aging actives.
How It Works
VA Liposome’s effectiveness hinges on its liposomal delivery system, which solves traditional Vitamin A’s three biggest flaws (irritation, instability, poor penetration) through science:
First, Liposomal Protection for VA Stability: Each Vitamin A molecule is encapsulated in a liposome— a tiny sphere made of phospholipids (e.g., phosphatidylcholine, identical to skin’s natural lipids). This shell acts as a “shield,” blocking oxygen (which oxidizes VA), light (which breaks down its structure), and heat (which deactivates it). Even in clear packaging or warm environments, VA remains active, ensuring every application delivers full potency.
Second, Targeted, Gentle Penetration: When applied to skin, liposomes’ phospholipid structure fuses with the stratum corneum (skin’s outer barrier) — a process called “fusion-mediated delivery.” Unlike unencapsulated VA (which struggles to cross the barrier and irritates surface cells), liposomes carry VA through the epidermis without causing damage. They then use “receptor-mediated endocytosis” to enter dermal cells (fibroblasts, keratinocytes) — targeting the exact cells responsible for collagen production and barrier repair.
Third, Slow, Steady Active Release: Once inside dermal cells, liposomes gradually degrade (triggered by skin’s natural enzymes), releasing Vitamin A in small, consistent doses. This avoids the “spike” of active VA that causes irritation and ensures levels stay high enough to drive results (e.g., activating fibroblast genes to produce collagen type I) for 12+ hours. The sustained release means fewer applications (once daily is enough) and longer-lasting effects.
Fourth, Multi-Pathway Skin Benefits: Released Vitamin A acts on two key pathways: 1) In the dermis, it binds to retinoic acid receptors (RARs) in fibroblasts, stimulating collagen and elastin synthesis to reduce wrinkles and sagging. 2) In the epidermis, it regulates keratinocyte turnover— clearing dead skin buildup for smoother texture without peeling. Meanwhile, the liposomes’ phospholipids replenish the barrier, fixing dryness and sensitivity from within.
