Ceramide

INCI: Ceramide NP

barrier-repair

Ceramides are lipid molecules that make up 50% of the skin's barrier. They lock in moisture, prevent transepidermal water loss (TEWL), and protect against environmental damage. Essential for dry, sensitive, and compromised skin.

Key Benefits

  • Restores and strengthens the skin's moisture barrier
  • Reduces transepidermal water loss (TEWL) by up to 50%
  • Calms sensitive and reactive skin
  • Protects against environmental stressors (pollution, UV, cold weather)
  • Improves skin texture and smoothness
  • Compatible with virtually all other skincare ingredients

Potential Side Effects

  • Extremely well-tolerated — side effects are very rare
  • May feel heavy in very humid climates if combined with occlusive oils

Frequently Asked Questions

What are ceramides and why do skin care products contain them?

Ceramides are natural lipids found in the skin barrier. They decline with age and environmental damage. Topical ceramides replenish these lipids to restore barrier function and reduce dryness.

Which ceramides are best in skincare?

Ceramide NP (ceramide 3) and Ceramide AP (ceramide 6-II) are the most common and effective in skincare. Products with multiple ceramide types provide better barrier restoration.

Can ceramides be used with niacinamide?

Yes — they are one of the best ingredient pairs in Korean skincare. Ceramides restore the barrier while niacinamide brightens and reduces pores.

Are ceramides safe for acne-prone skin?

Yes. Ceramides are non-comedogenic and recommended for acne-prone skin because a compromised barrier worsens breakouts. Look for lightweight, oil-free ceramide formulas.

Do ceramides help with eczema?

Yes. Clinical studies show ceramide-rich moisturizers significantly reduce eczema (atopic dermatitis) severity and frequency of flares.
