What oily skin is
Oily skin produces more sebum than it needs, so it tends to look shiny — particularly across the forehead, nose and chin — within a few hours of cleansing. It often comes with enlarged-looking pores , blackheads and a tendency to break out. Make-up may slide or separate during the day. There is an upside: oily skin often shows fine lines a little later. But when oil is out of balance, it can be frustrating to manage, especially in hot, humid weather.
Why it happens — and which layers are involved
Sebum is produced by oil glands that sit in the dermis and open onto the skin surface through the pores. How much oil they make is influenced by genetics, hormones, age, climate and stress. In our 8-layer Skin Architecture model, the visible effects are mostly in the epidermis and around the pore openings, while the glands themselves sit in the upper dermis .
One of the most common reasons oily skin gets worse is the way it is treated. Harsh foaming cleansers, alcohol-based toners and frequent scrubbing remove oil but also damage the barrier. The skin becomes dehydrated underneath, and in many people this goes hand in hand with even more shine and congestion. That is why oily skin can also be dehydrated at the same time.
How Obliv approaches oily skin
- Measure the balance. A director examines your skin from the first consultation, and Mark-Vu imaging analyses oil–moisture balance and pores. This shows whether you are oily and well-hydrated, or oily and dehydrated — two very different situations.
- Steady the barrier. Gentle barrier care with lightweight hydration helps the skin feel balanced rather than stripped, and supports other treatments.
- Address pores and congestion. Depending on what we see, your doctor may suggest our Pore Refining Program . Potenza RF microneedling is used for pores and texture with short downtime, and epidermis-level treatments such as NeoGen , a nitrogen-plasma skin regeneration device, may be considered for texture.
- Manage breakouts. If acne is part of the picture, a doctor examines it first and may recommend acne treatment alongside skin care.
- Hydrate without heaviness. Mirajet can deliver hyaluronic acid into the skin, adding water without adding oil.
What to expect
Oil production is partly genetic, so treatment aims to balance and manage it rather than switch it off. Many people notice skin feels more comfortable and looks less shiny once the barrier is steadier and the routine is simplified. Pore and texture treatments usually work over a course, with sessions spaced around the skin's roughly 28-day cycle. Potenza involves short downtime, typically some redness for a day or so. Results vary from person to person.
Caring for oily skin between visits
- Use a gentle, low-pH cleanser rather than a strong foaming one.
- Do not skip moisturiser — choose a light gel texture.
- Use SPF50+ daily in a lightweight, non-greasy formula.
- Avoid over-scrubbing and alcohol-heavy toners.
- Follow the pH-5.5-matched home care we prescribe.

Oily skin through the seasons in Seoul
Seoul has distinct seasons, and oily skin often behaves differently in each. Knowing what to expect helps you adjust your routine rather than fighting your skin.
- Summer: heat and humidity increase shine. Lighter gel moisturisers, blotting rather than repeated washing, and a non-greasy SPF50+ usually work better than stronger cleansers.
- Winter: cold, dry air outdoors and heated rooms indoors can dehydrate the surface, even while the T-zone stays oily. Many people need a little more hydration at this time of year.
- Spring and autumn: fluctuating temperatures can unsettle the barrier, so it is a good time for gentle barrier support.
If you are travelling from a different climate, your skin may take a few days to adjust. Our guide to skincare to bring home covers how to keep a routine steady after your trip, and our clear skin page explains how oil control fits into a wider plan.

Questions about oily skin
Can treatment stop my skin being oily?
Oil production is partly genetic, so the aim is balance rather than elimination. Treatment and the right routine may reduce shine and congestion. Results vary from person to person.
Should oily skin use moisturiser?
Yes. Skipping moisturiser can leave the skin dehydrated and unbalanced. A light, non-greasy formula is usually best.
Why is my skin oily and tight at the same time?
This often means the skin is oily but dehydrated, usually because of a weakened barrier. Mark-Vu imaging helps show this, and barrier care is the first step.
Will Potenza help with oily skin?
Potenza is mainly used for pores and texture. Whether it suits you depends on your skin, and your doctor will recommend the right option at consultation.
