1% Retinal at pH 5.0 — High-Potency Retinoid Serum for Renewal & Anti-Aging
Abib Red Effect Serum 1.05 Pump 30ml is a precision-formulated retinoid serum built around 1% Retinal (Retinaldehyde) at a skin-optimized pH of 5.0. The "1.05" in the name encodes the formula's exact specification: 1% Retinal concentration, pH 5.0 — Abib's commitment to transparency and formulation integrity in every product name.
Retinal (Retinaldehyde) is the most potent form of retinoid available without a prescription. As the direct precursor to Retinoic Acid, it converts in the skin with significantly greater efficiency than Retinol — delivering faster, more visible results with comparatively less irritation. At 1% concentration, this serum sits at the high end of OTC retinoid efficacy, making it one of the most powerful retinal serums available in the Korean beauty market.
Retinal works by accelerating the skin's natural cell turnover cycle, stimulating collagen production, reducing the appearance of fine lines and wrinkles, minimizing pores, evening skin tone, and combating the accumulated effects of photoaging. With consistent use, skin becomes progressively smoother, firmer, more refined, and visibly younger-looking.
The pump format keeps every dose protected from air and light exposure, preserving the retinal's potency from first use to last. The pH 5.0 formulation is carefully calibrated to support both retinal stability and comfortable skin tolerance, making this accessible even to those building up their retinoid routine.

Key Ingredient
-
Retinal (Retinaldehyde, 1%) at pH 5.0: The direct precursor to Retinoic Acid and the most efficacious OTC retinoid available. Converts to active Retinoic Acid in the skin with significantly greater speed and efficiency than Retinol, delivering clinical-grade anti-aging and skin renewal results. At 1% concentration and pH 5.0, this serum is formulated for maximum impact while maintaining an accessible tolerance profile for consistent use.
How to Use
- Use in the evening only — retinal increases photosensitivity.
- Apply after toner and essence, before moisturizer.
- Pump 1–2 times onto fingertips and gently press and spread across the face, avoiding the eye area.
- Follow immediately with a moisturizer to support the skin barrier during retinoid use.
- Always apply SPF the following morning.
- If new to retinoids, start 2–3 times per week and gradually increase to nightly use as skin builds tolerance.
- Avoid combining with other high-potency actives (AHAs, BHAs, Vitamin C) on the same night until skin is acclimatized.
- Store in a cool, dark place to preserve retinal stability.
