Oily Skin

Oily skin produces excess sebum, which can lead to shine, clogged pores, congestion, and breakouts. While oily skin may feel difficult to manage, maintaining hydration and supporting the skin barrier is still essential for balanced-looking skin.

At By Marilyn, we focus on gentle, glow-focused skincare inspired by K-beauty principles to help support clearer, healthier-looking skin without harsh stripping.

Common Signs of Oily Skin

  • Excess shine throughout the day
  • Enlarged or visible pores
  • Congested skin and breakouts
  • Makeup sliding or wearing off quickly
  • Greasy feeling, especially around the T-zone
  • Uneven texture

What May Cause Oily Skin?

Oily skin can be influenced by:

  • Genetics
  • Hormonal changes
  • Over-stripping skincare products
  • Dehydration causing excess oil production
  • Stress and environmental factors
  • Heavy or pore-clogging products

Our Approach

We believe oily skin still needs hydration and barrier support. Our skincare selections focus on:

  • Gentle cleansing
  • Lightweight hydration
  • Non-heavy skincare formulas
  • Barrier-supporting ingredients
  • Glow-focused routines inspired by K-beauty principles

Hydration Matters

Stripping oily skin too harshly can sometimes lead to even more oil production. A balanced, consistent routine can help support a fresher, smoother, and healthier-looking complexion over time.
