AESTURA A-CICA365 Blemish Calming Serum pH4.5 40ml is a high-performance, sub-acidic daily treatment engineered to rapidly calm sensitized skin, target stubborn post-breakout marks, and rebuild a severely compromised skin barrier. Powered by the proprietary A-CICA Complex (a targeted blend of Phytosterol, Beta-Glucan, and Madecassoside) and high-purity Niacinamide, this non-comedogenic serum is strictly calibrated to an optimal pH of 4.5. It works in perfect harmony with the skin's natural acidic mantle to instantly drop surface temperature, extinguish localized redness, and prevent trans-epidermal water loss (TEWL), leaving a reactive, hyperpigmented, or acne-prone canvas remarkably smooth, perfectly even, and glowing with a fresh glass-skin finish.

  • Target Concerns: Post-Breakout Marks & Hyperpigmentation, Weakened Acid Mantle & Redness, Acute Sensitivity & Inflammation, Dull & Uneven Skin Tone, Dehydration & Inner Tightness
  • Skin Compatibility: All skin types (Highly optimized for sensitive, acne-prone, reactive, and barrier-damaged skin profiles requiring advanced blemish-fading care and optimal pH stabilization)
  • Texture & Finish: A lightweight, moisture-rich fluid serum that glides effortlessly across the face with zero physical drag, absorbing instantly without stickiness to leave a calm, plumped, and beautifully fresh satin baseline.

Transform your daily hydrating and spot-correcting step into an advanced clinical skin-cooling, pH-stabilizing, and barrier-rehabilitation ritual. For highly sensitive and acne-prone skin profiles, managing the aftermath of breakouts is a constant biological struggle. When a breakout subsides, it often leaves behind stubborn post-inflammatory hyperpigmentation (PIH) and localized redness. Simultaneously, the skin's natural pH often rises above its healthy acidic baseline, weakening the protective acid mantle. This compromised state allows harmful bacteria to multiply, triggers chronic micro-inflammation, and accelerates trans-epidermal water loss (TEWL)—leaving the cells parched, tight, and highly reactive. The AESTURA A-CICA365 Blemish Calming Serum pH4.5 40ml systematically solves this multi-layered dilemma.

Formulated to perfectly respect fragile, highly reactive, and acne-prone epidermal ecosystems, this premium daily serum is strictly calibrated to a sub-acidic pH of 4.5 to instantly restore and reinforce the skin's natural acidic shield. It is built on a foundation of Aestura’s proprietary A-CICA Complex—a high-performance synergy of Phytosterol, Beta-Glucan, and Madecassoside encapsulated into micro-liposomes to ensure rapid, deep-level delivery past the stubborn stratum corneum. Working in perfect harmony with high-purity Niacinamide (Vitamin B3), it clinically blocks the transfer of melanin to the epidermal surface, preventing new dark spots from forming while actively fading existing post-acne marks and unifying uneven tone. It converts an angry, pigmented, or pH-unbalanced face into an exceptionally uniform, bouncy, and flawlessly balanced water-glow canvas.

  • Sub-Acidic pH 4.5 Stabilization: Calibrates the skin to an optimal, healthy pH level of 4.5 to reinforce the natural acid mantle, suppress acne-causing bacteria, and block trans-epidermal water loss (TEWL).
  • Proprietary A-CICA Recovery: Satiates highly sensitized and troubled skin with micro-liposome-encapsulated Madecassoside, Phytosterol, and Beta-Glucan for accelerated barrier repair.
  • Post-Breakout Blemish Fading: Infuses high-purity Niacinamide to actively target and fade stubborn post-inflammatory hyperpigmentation (PIH), evening out skin tone and clearing sallow undertones.
  • Frictionless Hydration Plumping: Floods parched dermal tracks with multi-dimensional moisture, instantly eliminating inner tightness and smoothing away rough micro-textures.

Key Ingredients

  • A-CICA Complex (Madecassoside, Phytosterol, Beta-Glucan): A specialized, bio-compatible soothing active that rapidly targets skin redness, calms active irritation, and rebuilds a broken lipid barrier.
  • Niacinamide (Vitamin B3): A gold-standard brightening active that blocks melanin transfer, reduces post-acne marks, and unifies uneven skin tone.
  • pH 4.5 Balancing Matrix: A finely tuned buffering system that maintains the serum at a sub-acidic pH of 4.5, strengthening the skin's natural defense shield.
  • Allantoin & Panthenol: A powerful soothing and skin-conditioning duo that protects raw skin, calms physical skin stress, and reinforces the protective moisture barrier.

  • Step 1: Use daily during your morning (AM) and evening (PM) skincare routines. Apply after cleansing and toning, as your main active treatment step before your moisturizer.
  • Step 2: Pump an adequate, dime-sized amount (1 to 2 pumps) of the serum onto your clean fingertips.
  • Step 3: Smooth the lightweight fluid evenly across your face and neck, moving gently outward along your skin's natural contours. Focus extra attention on areas with active redness, breakouts, or dark marks.
  • Step 4: Lightly pat with your fingertips to encourage complete, instantaneous absorption. Follow up with your daily moisturizer and sunscreen.

✨ The Ultimate "pH-Balancing Blemish Compress" Pro-Tip: On days when your skin is experiencing a severe sensitive flare-up, intense localized redness from a sudden pH imbalance, or when post-acne marks look exceptionally dark and sallow, try this professional "targeted layering" method.

After applying your daily sub-acidic toner, apply a thin layer of the A-CICA365 Blemish Calming Serum over your entire face and let it fully absorb for 30 seconds.

Then, squeeze an extra pump of the serum onto clean, thin cotton pads and press them specifically onto your primary blemish or redness zones—such as your cheeks, chin, or jawline—gently pressing them in without rubbing.

Leaving these targeted pads on for 3 to 5 minutes acts as an airtight, highly breathable compression shield. It traps the micro-encapsulated A-CICA molecules, Niacinamide, and soothing Panthenol directly within the hyperpigmented tracks at an optimal pH 4.5 environment, preventing overnight moisture loss while maximizing spot-fading and skin-calming efficacy. You will wake up to an incredibly smooth, calm, and flawlessly brightened glass-skin canvas!
