Oily, shiny skin

What Causes Oily Skin?

The size and activity of sebaceous glands are determined by genetics and androgen hormones, which is why oily skin typically begins during puberty and persists over time. High temperatures and humidity (such as Vietnam's climate) cause sebum to liquefy and spread more rapidly across the skin's surface. Stress and sleep deprivation also increase oil production via cortisol. Lastly, skincare habits play a role: over-washing, using harsh foaming cleansers, applying alcohol-based toners, and skipping moisturizer dehydrate the upper layers of the skin, triggering the sebaceous glands to overcompensate by producing even more oil.

Truly Oily Skin vs. Dehydrated Skin Overcompensating with Oil

Truly oily skin presents with uniform shine across the entire face, enlarged pores on the cheeks, and rarely feels tight or irritated. In contrast, dehydrated skin overcompensating with oil is shiny in the T-zone while the cheeks feel tight, mildly flaky, or experience a stinging sensation upon product application—indicating a compromised skin barrier that must be repaired before addressing oil control. Confusing these two conditions is why many individuals find their skin becoming progressively oilier the more mattifying products they use.

How Is Oily Skin Linked to Congested Pores and Enlarged Pores?

Excess sebum mixes with dead skin cells to form follicular plugs, resulting in closed comedones and blackheads. As hair follicles become chronically distended with sebum over time, pores appear enlarged, particularly on the nose and inner cheeks. Controlling excess oil is the foundational step in improving both associated concerns.

What Determines the Degree of Improvement?

Genetically predisposed oily skin cannot be permanently "cured," but it can be effectively managed: a proper skincare routine visibly reduces shine; topical active ingredients (retinoids, niacinamide, exfoliating acids) decrease sebum production and prevent congestion; and in-clinic procedures like chemical peels and laser toning provide additional support when indicated. Sustained results depend on maintaining consistent skincare habits.

How Does BonBoz Approach Oily Skin?

Our dermatologists conduct a thorough skin analysis to distinguish truly oily skin from dehydrated skin and to assess the extent of congestion and underlying comedones. The treatment protocol includes a streamlined, targeted skincare routine for oily skin, step-up concentrations of sebum-regulating active ingredients, medical-grade comedone extractions, and periodic chemical peels for significant congestion; laser toning is utilized for enlarged pores and excessive shine when appropriate. The dermatologist closely monitors progress and tailors the regimen based on the skin's actual clinical response.
