K-Beauty Routine for Oily, Pore-Prone, and Blackhead-Prone Skin — A Deep Cleansing Guide to Dissolve Sebum and Smooth Pore Texture

Are you troubled by blackheads on your nose and chin that seem to fill back up just one day after you squeeze them? Excess oil, often called "grease," is produced inside the pores of oily skin; when it meets the air, it oxidizes, hardens, and turns black, creating noticeable texture. If you try to remove this with harsh adhesive pore strips, you risk stretching the surrounding skin's elasticity, causing pores to look even more like orange peels.

This guide details a specialized 4-step K-Beauty routine for oily, pore-prone skin that gently dissolves hardened, oil-soluble sebum without irritation and calms sebaceous gland activity to prevent blackhead formation early on.

In this guide, you will learn:

• The causes of how oxidized sebum in oily skin pores turns into blackheads

• A 4-step daily routine that emulsifies, cleanses, and tightens pores

• A list of representative Olive Young products proven for blackhead relief and sebum control

• Pore-targeting ingredient formulas using BHA, Niacinamide, Green Tea, and Cica

⚖️ The Essence of Oily Pore Care: Emulsifying Oil-Soluble Keratin and Sebum Control Shield

The ultimate secret to oily pore and blackhead care is to 'emulsify the hardened oil deposits within the pores to loosen and remove them, while slowing down the secretion speed of the sebaceous glands.' Simply wiping your skin with alcohol-based toners to evaporate oil rapidly only leads to dryness, which triggers a "rebound" sebum effect.

To solve this, K-Beauty primarily uses Salicylic Acid (BHA), which penetrates the oil-soluble sebum in the pores to gently dissolve keratin texture.

Following this, we add niacinamide to control sebum activity and help tighten pore surface area, paired with Cica to soothe aggravated pore openings and tannin-rich green tea essence to provide hydration evenly.

☀️ Morning (AM) Routine: Clearing Overnight Oil and Calming Sebum

In the morning, the goal is to gently clean the sebum secreted during sleep that covers the pores, and to form a light, refreshing oil-control barrier that prevents sebum from erupting and oxidizing during the day.

Step 1: Salicylic Acid Low-pH Cleansing Foam

Use a low-pH foaming cleanser containing salicylic acid—which is excellent for cleaning oily skin texture without being irritating—to gently wipe away oil around the nose and forehead.

Step 2: Sebum-Controlling Green Tea Toner (Wiping & Patting)

Apply a toner containing tannins and green tea catechins (known for sebum control and heat reduction) to a cotton pad to wipe and tidy the oily T-zone, then gently pat to ensure it adheres to the skin.

• Synergy Ingredient: Green Tea Extract

Step 3: Low-Irritation Hydrating Ampoule

Avoid oils that might block pores and cause acne. Instead, apply a low-molecular-weight hyaluronic acid soothing serum to replenish inner elasticity with 100% moisture.

• Synergy Ingredient: Hyaluronic Acid 👉 Innisfree Green Tea Seed Hyaluronic Serum

Step 4: Matte Sebum-Controlling Gel Soothing Cream

Finish by applying a very thin layer of an oil-free gel cream or Cica soothing cream to calm surface shine while leaving only a refreshing feeling of moisture.

• Synergy Ingredient: Cica / Centella 👉 Skin1004 Madagascar Centella Ampoule

🌙 Evening (PM) Routine: Emulsifying Blackheads and Pore Tightening

The evening care step is dedicated to gently melting away the blackheads that have hardened in the pore openings and applying niacinamide to help restore pore elasticity overnight.

Step 1: Cleansing Oil for Melting Blackheads + Salicylic Foam (Double Cleansing)

Apply cleansing oil to a dry nose and roll gently over blackheads for 1 minute. Add water to emulsify for 30 seconds, rinse clean, and follow with a secondary wash using salicylic acid foam.

Step 2: BHA Pore Purifying Serum / Toner (2-3 times a week)

Use a BHA peeling essence on a cotton pad to wipe areas with texture, cleaning the deep oil channels and dissolving whiteheads.

• Synergy Ingredient: BHA (As of May 2026)

Step 3: Sebum-Controlling Niacinamide Serum

To prevent permanent pore enlargement due to stagnant sebum, apply niacinamide serum, focusing on wide-textured areas like the nose, forehead, and cheeks.

• Synergy Ingredient: Niacinamide 👉 COSRX The Niacinamide 15 Serum

Step 4: Non-Comedogenic Lightweight Cream

Finish with a thin layer of a non-comedogenic certified Cica soothing cream that balances oil and moisture without stickiness or pilling.

• Synergy Ingredient: Cica / Centella 👉 Skin1004 Madagascar Centella Ampoule

🙋 Frequently Asked Questions (FAQ)

Q1. Is it effective to squeeze blackheads with tweezers or press them firmly with a cotton swab?

No. Forcibly squeezing blackheads around the nose with your fingers, tweezers, or cotton swabs can tear the elastic fibers supporting the pore walls, leading to permanently enlarged pores and uneven scarring. Rather than using physical force, it is safer and more effective to use a cleansing oil to emulsify and dissolve the hardened sebum, followed by consistent BHA treatment, which is the reliable K-Beauty pore improvement guide.

Q2. My skin produces too much sebum; is it okay to skip moisturizing cream at night?

Even for oily skin, cutting off hydration after washing will signal your skin to protect its dry barrier, causing it to produce even more sebum than usual, accelerating the "oil factory" phenomenon. The key tip for controlling sebum is to apply a thin layer of an oil-free formula or a refreshing gel soothing cream that manages shine without clogging pores, which helps balance oil and moisture.

Q. Do enlarged pores and blackheads look more prominent depending on skin tone?

Yes. The lighter the skin tone, the more the black color of the blackheads contrasts, making them stand out. The darker the skin tone, the more post-pore hyperpigmentation makes the pores appear like deep pits. Especially for darker skin tones, it is crucial to apply a niacinamide serum after BHA exfoliation to manage melanin deposits around the pores, preventing them from appearing even more prominent.
