Medicube Zero Pore One Day Serum 30ml is a targeted pore-care serum designed to "temporarily refine pores + long-term improve oil balance," with a focus on quick results for daily or special-occasion use. Its core features are:

1. Dual Pore-Care: Temporary Tightening + Long-Term Improvement: Contains "instant pore-converging agents" (e.g., niacinamide, zinc PCA) that temporarily shrink pore appearance by constricting skin pores and absorbing excess oil (visible within 1-2 hours). For long-term benefits, it also includes ingredients that regulate sebum production (e.g., salicylic acid) to prevent pore enlargement over consistent use.
2. Oil-Control & Shine Reduction: The lightweight, oil-free formula absorbs excess sebum on the skin surface and in pores, reducing midday shine without stripping the skin of natural oils— keeps the T-zone matte and fresh for 6-8 hours.
3. Gentle Exfoliation & Hydration: Infused with mild BHA (salicylic acid) that penetrates pores to dissolve dead skin cells and blackhead-causing impurities, preventing pore congestion. It also contains hyaluronic acid to hydrate the skin, avoiding dryness that can trigger excess oil production.
4. Makeup-Friendly Texture: Has a lightweight, watery-serum texture that absorbs quickly into the skin without leaving a sticky residue or white cast. It acts as an excellent makeup base—primes the skin, helps foundation adhere better, and prevents makeup from settling into pores (no "cakey" look).
5. Safe, Fragrance-Free Formula: Free of ethanol (harsh alcohol), synthetic fragrances, parabens, mineral oil, and sulfates—tested for sensitive skin by dermatologists, making it suitable for daily use and compatible with most skincare routines.

（specific ingredients subject to product packaging; core components listed below）：
Pore-Converging & Oil-Control Actives:
Niacinamide (Vitamin B3): Reduces sebum production by regulating sebaceous gland activity, temporarily tightens pores by improving skin elasticity, and fades post-inflammatory hyperpigmentation (PIH) caused by blackheads.
Zinc PCA: A natural mineral derivative that absorbs excess sebum on the skin surface, reduces shine, and has anti-inflammatory properties—prevents pore congestion and soothes mild redness.
Salicylic Acid (BHA): A lipid-soluble acid that penetrates pores to dissolve dead skin cells, blackheads, and excess oil—unclogs pores, prevents acne, and refines pore texture with long-term use.
Hydrating & Barrier-Protecting Ingredients:
Sodium Hyaluronate (Hyaluronic Acid): Multi-molecular hyaluronic acid that hydrates the skin at different layers—prevents dryness (which can trigger excess oil production) and plumps the skin to reduce the appearance of fine lines around pores.
Panthenol (Vitamin B5): Converts to pantothenic acid in the skin, which repairs the skin barrier, soothes irritation from BHA, and enhances the skin’s ability to retain moisture—avoids over-drying.
Soothing & Irritation-Reducing Additives:
Centella Asiatica Extract (Cica): Contains asiaticoside and madecassic acid—calms inflammation caused by oil buildup or BHA, repairs damaged skin around pores, and reduces redness.
Allantoin: Softens the skin, promotes mild cell renewal, and soothes discomfort from dryness or tightness—ideal for sensitive skin using BHA for the first time.
Texture & Absorption Aids:
Glycerin (Vegetable-Derived): A humectant that enhances hydration and improves the serum’s spreadability—ensures even application without leaving a sticky residue.
Betaine: An amino acid-derived moisturizer that maintains skin pH balance, reduces irritation from oil-control ingredients, and gives the serum a lightweight, fast-absorbing texture.
Safety & Quality Assurance:
Free of ethanol (harsh alcohol), synthetic fragrances, parabens, mineral oil, sulfates (SLS/SLES), and synthetic colorants—tested for skin irritation by third-party dermatological laboratories, compliant with global skincare safety standards (e.g., EU REACH, US FDA).
Note: If you have a history of BHA sensitivity, start with 1-2 times weekly to build tolerance. Discontinue use if severe irritation (peeling, intense itching) occurs.

Use in Morning (or Before Special Occasions): For daily oil control and pore refinement, apply in the morning after cleansing and toning (it works well as a pre-makeup step). For special occasions, apply 1-2 hours before makeup to maximize temporary pore-tightening effects.
Skin Prep: Start with a clean, dry face. Use a gentle cleanser to remove dirt and excess oil, then apply an alcohol-free toner to balance skin pH. Pat the toner dry—avoid applying the serum to damp skin (damp skin may increase oil absorption too quickly, causing temporary tightness).
Application Amount & Technique: Pour 2-3 drops of serum into the palms of your hands. Rub your palms lightly to warm the serum, then gently press it onto the face—focus on pore-prone areas (T-zone: forehead, nose, chin). Avoid rubbing or stretching the skin; pressing enhances absorption and ensures even coverage.
Wait for Absorption: Allow the serum to fully absorb for 1-2 minutes (it should feel dry to the touch, with no stickiness). Do not rush to apply subsequent products (e.g., moisturizer, sunscreen, foundation) as this may cause pilling.
Follow-Up Skincare/Makeup: After absorption, apply a lightweight, oil-free moisturizer (for dry/combination skin) or skip moisturizer (for oily skin) if preferred. Then apply broad-spectrum sunscreen (SPF 30+)—critical for protecting the skin and preventing pore damage from UV rays. For makeup, apply foundation directly after sunscreen— the serum will help foundation look smoother and last longer.
Evening Use (Optional): For oily skin with severe pore congestion, you can use it 2-3 times weekly in the evening (after cleansing/toning) to enhance oil control and pore-cleansing effects. Follow with a moisturizer to avoid dryness.
