Instantly clear sebum-clogged nose and dense blackheads after 1 Deep Sebum Cleansing session in Da Nang

*Real case series · Coleni Beauty

For oily skin, the nose and T-zone are often the most “stubborn” areas: oil returns quickly, pores enlarge easily, blackheads build up densely, and the more thoroughly you try to wash, the less completely the issue is resolved. The real case below was recorded on a 26-year-old female client with severe sebum congestion on the nose and T-zone. After 1 session of Deep Sebum Cleansing combined with Enzyme + Aqua + Greek oil-control mask at Coleni Beauty Da Nang, the skin surface was instantly cleaner, pores were noticeably clearer, and blackheads were treated within the same session.

What stands out in this case is not a single step, but the cleansing method in the correct order: soften first, extract thoroughly, then rebalance. This is also why many people with oily skin wash their face regularly but still have a nose full of blackheads: the issue lies deep inside the pores, not only on the surface.

Background

Item	Initial information
Age	26 years old
Gender	Female
Skin type	Oily skin, large pores
Main condition	Deep sebum congestion on the nose and T-zone, dense blackheads, visibly enlarged pores
Recorded timeframe	Results observed within the same treatment session
Notable signs	Shiny oily nose, congested nostril sides, rough texture, dense blackheads, visible pores
Contributing factors	Overactive sebaceous glands in the T-zone, long-term oil buildup oxidizing into blackheads
Client’s goal	Deeply cleanse sebum, reduce blackheads on the nose, help the skin feel clearer and make pores less visible

This case is quite typical for people with oily skin living in a hot and humid environment like Da Nang. When excess oil is continuously produced but not removed properly, pores become filled layer by layer. The congestion gradually settles deeper, then the part exposed to air at the pore opening oxidizes and turns black. If you only use cleanser or nose strips, the top layer may improve temporarily, but the “root” of the sebum buildup remains.

Diagnosis

Before treatment, the Skin Coach at Coleni examined the skin and assessed the level of congestion to determine the appropriate approach. The diagnosis in this case focused on the true nature of the problem: this was a condition of deep sebum accumulation and dense blackheads, not just surface oil.

Assessment content	Findings
Main affected areas	Nose, nostril sides, and T-zone
Degree of congestion	Severe, clearly accumulated inside the pores
Visible lesion type	Dense blackheads, enlarged pores, shiny oily skin surface
Mechanism causing the condition	Sebaceous glands continuously produce oil, while oil and residue accumulate inside the pores and oxidize
Why normal face washing is not enough	It only cleans the oil and dirt on the surface, not the deeply attached sebum
Suitable indication	Layer-by-layer cleansing process: Enzyme softens, Aqua extracts, Greek mask rebalances after cleansing

In short, this is not skin that needs “stronger exfoliation,” but skin that needs a properly structured process. If the softening step is skipped, extraction will be less effective. If you only extract without rebalancing afterward, the skin can quickly become oily again. That is why Coleni recommended the Deep Sebum Cleansing treatment instead of a single cleansing step.

Solution

The solution used in this case was Deep Sebum Cleansing in a 3-in-1 model, including three sequential mechanisms:

1. Enzyme — softens and loosens sebum

The first step uses bio-enzyme combined with steam to soften the sebum buildup inside the pores. This is a very important step because when sebum is still “hardened” and tightly stuck, the cleansing steps afterward will not be thorough. Enzyme works by helping break down the bonds that keep oily residue attached, making the removal process gentler and more effective.

2. Aqua — extracts thoroughly from inside the pores

After the sebum is softened, Aqua technology with a water-pressure suction mechanism is used to deliver actives and remove congested residue in the same step. In this case, Aqua was combined with AHA/BHA/HYD according to the treatment history provided. The strength of this step is that it supports deep cleansing without the need for strong mechanical pressure on the nose area, which is often prone to redness and sensitivity after extraction.

If a client needs a more basic water-based cleansing treatment for oily skin or skin that feels tired after congestion, they can also explore Aqua Cleansing.

3. Greek oil-control mask — balances oil and helps refine pores

After the pores have been cleared, an oil-control mask made from Greek seaweed is used to absorb remaining excess oil, help rebalance the skin surface, and make pores appear more refined after the treatment session. This is a very important finishing step so the result is not only “instantly clean,” but also comfortably clean and less oily.

This entire method is suitable for oily skin, blackheads on the nose, and large pores caused by long-term sebum buildup. It is also a reasonable preparatory step before starting other recovery or advanced skincare treatments such as Skin Recovery if the skin also has sensitivity or redness.

Procedure

Below is the 6-step process that was performed at Coleni Beauty in this case:

1. Coleni-standard 5-step deep cleansing
   Remove dirt, excess oil, sunscreen residue, and product buildup remaining on the skin surface, creating a clean base for the following steps.

2. Enzyme therapy combined with steam
   Supports controlled pore opening and softens sebum buildup from the root.

3. Aqua with AHA / BHA / HYD
   Cleansing is performed using a water-pressure suction mechanism to remove sebum and impurities from the pores.

4. Extraction of remaining blackheads and hidden comedones
   Treats the leftover congestion after the skin has been softened and most buildup has already been extracted.

5. Greek oil-control mask
   Balances oil, soothes the skin surface, and helps pores appear more refined after cleansing.

6. Nutrient infusion and sunscreen
   Supports surface recovery after deep cleansing and protects the skin immediately after the session.

Step	Treatment performed	Main goal
1	5-step deep cleansing	Cleanse the surface, prepare the skin
2	Enzyme + steam	Soften sebum, loosen congested residue
3	Aqua with AHA/BHA/HYD	Extract excess oil and impurities from the pores
4	Blackhead & hidden comedone extraction	Complete the cleansing of remaining buildup
5	Greek oil-control mask	Balance oil, help refine the pore surface
6	Nutrient infusion + sunscreen	Soothe and protect the skin after the session

Progress

The before-and-after images in this case show a clear difference focused on the nose area: from a congested, oily, blackhead-heavy condition to a cleaner and more breathable surface immediately after the first session.

Alt: The before-treatment image shows obvious sebum congestion on the nose and nostril sides, dense blackheads, enlarged pores, and an oily T-zone.

Alt: The after-treatment image shows the nose area cleared of sebum, visibly reduced blackheads, clearer pores, and a smoother skin surface within the same session.

The most valuable point here is that the result was achieved without aggressive manipulation that causes prolonged redness. This is also a major difference between properly prepared deep cleansing and the habit of trying to remove blackheads at home.

Results

Indicator	Observation after the first session
Sebum on the nose	Completely cleansed according to the case record
Blackheads	Instantly extracted clean
Pores	Clearer, visibly smaller in appearance
T-zone oiliness	Clearly reduced
Sensation during treatment	Painless
Post-treatment irritation	No significant irritation recorded
Downtime	None needed
Session duration	About 90 minutes

Why did this case show good results after just 1 session?

• The issue was treated at its root: not just wiping away surface oil, but addressing the congestion inside the pores.
• The treatment order was logical: Enzyme softening first helped Aqua work more effectively.
• There was a balancing step after cleansing: the Greek mask helped the skin feel less oily and made pores appear more refined after being cleared.
• Mechanical force was not overused: reducing the risk of prolonged redness and irritation on the nose.

Recommended maintenance plan

For oily skin with recurring blackheads, Coleni recommends maintenance once every 3–4 weeks to keep pores clear. In cases of heavy oil production and fast blackhead recurrence, the interval can be shortened to once every 2–3 weeks depending on the actual skin condition observed during analysis.

Related maintenance options may include:

• Deep Sebum Cleansing for prominent oil congestion and blackheads
• Aqua Cleansing if gentler regular water-based cleansing is needed
• Bubble Detox or Orgahue Deep Detox if the goal is more focused on detox and cleansing congested, dull skin

“After the first session, my nose area was so much cleaner, looked noticeably clearer, and my skin wasn’t red or irritated like I had worried.”

Who is this suitable for?

• Oily skin, especially with heavy oil in the nose and T-zone
• People with blackheads, whiteheads, or thick congested residue on the nose
• Large pores caused by long-term oil and sebum buildup
• Skin that feels congested, heavy, and still not truly clean even after washing
• People who want to cleanse the skin base before starting another nourishing or recovery treatment
• People who need regular maintenance to keep skin clear in a hot, humid climate like Da Nang

Lessons / Key takeaways

• A clean face does not always mean clean pores. Surface oil and deeply accumulated sebum are two different issues.
• Softening before extraction greatly improves effectiveness. For skin with dense blackheads, the treatment order matters as much as the technology.
• Pores look smaller when they are properly cleared. Not because they are “forcefully tightened” instantly, but because they are no longer filled with oily residue.
• Maintaining the right rhythm is more effective than overdoing it. For oily skin, regular deep cleansing is often more sustainable than continuous at-home blackhead removal.

Frequently asked questions / FAQ

Can Deep Sebum Cleansing remove blackheads on the nose?
Yes — Deep Sebum Cleansing combines 3 methods: Enzyme softens and loosens sebum inside the pores, Aqua (water-pressure suction) extracts sebum and impurities, and the Greek oil-control mask balances and tightens pores afterward. Results are usually visible right after the first session.

Will pores become larger after Deep Sebum Cleansing?
No — the process is designed not to cause irritation. The Enzyme + steam step opens pores in a controlled way, then the Greek mask helps refine them afterward. Skin usually looks smoother and pores appear less visible immediately after the session.

How often should oily skin with blackheads do Deep Sebum Cleansing?
It is recommended once every 3–4 weeks to maintain clear pores and stable oil control. For very oily skin with quickly recurring blackheads, the interval can be shortened to every 2–3 weeks depending on the condition.

Is Deep Sebum Cleansing painful? Is there any downtime?
It is painless and requires no downtime. All steps are performed gently, without causing swelling or prolonged redness. Clients can go out and resume normal activities immediately after the session.
