ARENCIA Retinal Booster Night Serum 30ml — Firming Retinal with Caffeine & Ectoin for Mature Skin, Pore Refining

ARENCIA Retinal Booster Shot Serum is an advanced night serum that blends retinal with caffeine and ectoin to help firm mature skin, refine pores, and smooth fine lines.

Designed for evening use, this lightweight 30 ml Korean-style serum layers easily under moisturizers to deliver targeted firming and texture refinement. The formula emphasizes retinal—a vitamin A derivative—paired with protective ectoin and energizing caffeine, plus peptides and nourishing lipids to support hydrated, resilient-looking skin without heaviness.

How will this serum help uneven texture and visible pores?

The retinal in this booster encourages cellular turnover and surface smoothing, which can reduce roughness and make pores appear less prominent over time. Complementary ingredients help maintain hydration so skin doesn’t feel tight while it renews.

• Retinal promotes gentle exfoliation to reveal smoother skin.
• Ectoin protects cells and improves moisture retention.
• Peptides support a firmer-looking complexion.

Will the formula feel heavy or cause irritation at night?

This serum was formulated to be lightweight and fast-absorbing, minimizing stickiness and layering comfortably under night creams. Because retinal can increase sensitivity for some users, the product is intended for gradual introduction into routines to monitor tolerance.

• Non-greasy texture absorbs quickly for easy layering.
• Contains nourishing lipids to soothe and prevent over-drying.
• Start with alternate-night use to assess skin response.

How does caffeine and ectoin contribute to results?

Caffeine delivers a tightening sensation and may temporarily improve the look of puffiness or firmness, while ectoin acts as a cellular protectant that helps maintain skin moisture and resilience. Together they enhance the serum’s visible smoothing and comfort benefits during overnight use.

• Caffeine provides immediate skin-firming and energizing effects.
• Ectoin boosts environmental protection and hydration.
• Peptide blend supports long-term elasticity and tone.

How should I incorporate this serum into my evening routine?

Use the retinal booster in the evening after cleansing and any water-based treatments, then follow with a lightweight moisturizer if needed. Apply a small amount to targeted areas or the entire face, and increase frequency as your skin adapts.

• Cleanse and tone, then apply a pea-sized amount of serum.
• Layer a hydrating moisturizer over the serum for added comfort.
• Use SPF during daytime—retinoids can increase sun sensitivity.

Who is this for: ARENCIA Retinal Booster Shot Serum is aimed at mature skin types seeking a gentle but effective overnight treatment for firmness, texture refinement, and the appearance of fine lines. It suits users who want a lightweight, easily layered serum with active ingredients like retinal, caffeine, peptides, and ectoin. If you have very sensitive skin or are using other strong actives, introduce the serum slowly and consult patch-testing practices.
