Oily skin, enlarged pores, and the constant appearance of various types of acne are clinical manifestations of excessive sebum secretion. This is not merely an innate skin characteristic but is also complexly influenced by hormonal factors and daily skincare routines. Understanding the mechanism of sebaceous gland activity is key to establishing an effective and sustainable oil control regimen.

1. Biological mechanism of excessive sebum secretion

Sebaceous glands produce lipids to maintain skin moisture and strengthen the skin's protective barrier. However, when sebaceous gland cells become overactive, excess oil combines with dead skin cells, blocking the hair follicle opening.

Key factors that promote this process include:

• Hormones: Increased androgen levels stimulate receptors on the sebaceous glands, leading to an increase in gland size and oil production rate.

• Genetic factors: The density and size of sebaceous glands are highly hereditary, determining each individual's natural oil secretion tendency.

• Environmental impacts: High temperature and humidity alter the viscosity of sebum, making oil spread more easily on the skin's surface.

• Nutrition: High Glycemic Index (GI) foods increase insulin levels, thereby indirectly stimulating increased oil secretion through insulin-like growth factor (IGF-1).
  

Oily skin results from many contributing factors, from genetics to lifestyle habits.

2. Consequences of incorrect sebum control methods

One of the most common mistakes in oily skin care is attempting to completely remove the surface oil layer through mechanical or harsh chemical methods.

Over-cleansing and skipping moisturization are the two biggest mistakes when caring for oily skin

• Over-cleansing: Using harsh cleansers damages the protective lipid barrier, leading to transepidermal water loss (TEWL). In response, the skin activates a compensatory mechanism by secreting more oil to protect the surface, creating an uncontrolled oil secretion loop.

• Skipping moisturization: Oily skin can still experience dehydration. When intrinsic moisture is not maintained, the imbalance between oil and water will make the skin rough yet still shiny.

• Lack of SPF protection: UV rays not only cause cellular DNA damage but also oxidize sebum (Squalene oxidation), a primary factor causing inflammation and blackhead formation.
  

3. Sebum regulation and skin balance restoration regimen

To effectively control oil, oh!oh! recommends a biological regulation approach instead of temporary inhibition:

1. Gentle cleansing: Use selective surface cleansing agents to remove excess sebum without compromising the natural skin barrier.

2. pH balancing: Maintain an ideal pH (around 5.5) to inhibit the growth of acne bacteria and stabilize the activity of skin enzymes.

3. Moisturize with suitable texture: Prioritize lightweight serum or gel-cream products containing active ingredients that can deeply penetrate and regulate sebocyte activity.

If you are looking for a formula capable of directly intervening in the oil secretion process, oh!oh! Skin Health Serum is the optimal solution. The product boasts a high concentration of active ingredients that visibly transform oily, acne-prone skin.

oh!oh! Skin Health Serum is a comprehensive solution for balancing excess oil and nourishing healthy skin

✦ The power of 20% Niacinamide (Vitamin B3): At this concentration, Niacinamide acts as a powerful sebum regulator, helping to minimize pores and effectively reduce inflammation. This is a rare active ingredient capable of balancing oil and water levels while strengthening the skin's protective lipid barrier.

✦ Perfect combination with 2% Acetyl Glucosamine (NAG): Enhances brightening and prevents post-acne hyperpigmentation. The combination of Niacinamide and NAG creates a synergistic effect, making the skin not only clearer but also more even-toned and smoother.

✦ Superior absorption: The product is optimized in texture, ensuring quick absorption without leaving any sticky or clumpy residue – an important factor for users with oily skin.
