The skin around the eyes has fewer sebaceous glands than other facial areas and is about 0.5mm thick — a quarter of the overall facial average (2mm). This makes it prone to dryness and the first area to show aging signs (fine lines, sagging, dark circles).
Characteristics of eye-area skin
Fast water loss: With few sebaceous glands, the skin's own oil supply is insufficient. In dry environments or with heating/AC, the eye area tightens and fine lines form easily.
Sensitive to irritation: Thin skin reacts easily to external irritants. Using strong actives around the eyes can cause irritation, swelling, and inflammation.
Repetitive muscle movement: Blinking and making expressions over 10,000 times a day applies constant physical stress to the skin.
Why you need eye cream
Eye cream, compared to a regular face cream, ① has higher oil content specialized for eye-area moisture, ② excludes irritants like fragrance and alcohol, and ③ contains ingredients specialized for the eye area.
Using a regular face moisturizer around the eyes provides basic hydration, but fragrance or certain actives can irritate the eye-area skin. Using a dedicated product for the sensitive eye area is safer.
Recommended ingredients by eye concern
Fine lines/loss of elasticity
- Retinol: 0.025–0.05% low concentration. Stimulates collagen. Start 2 times a week
- Peptides: Matrixyl, acetyl hexapeptide. Improve elasticity without irritation
- Niacinamide: moisturizing + tightening effect
Dark circles
Identify the cause first.
- Vascular (bluish): caffeine, vitamin K — improve circulation
- Pigment (brown): alpha-arbutin, niacinamide, vitamin C — suppress melanin
- Hollow (shadow): improve volume with moisturizing/elasticity ingredients (filler is a dermatology matter)
Eye-area puffiness
Caffeine, with its vessel-constricting action, helps temporarily reduce puffiness. More effective when used in the morning.
Dryness/flaking
Choose a moisture-focused eye cream with ceramides, hyaluronic acid, and squalane.
How to use eye cream properly
- Use your ring finger: Apply with the weakest finger, the ring finger, in a gentle tapping motion. Rubbing or pulling causes skin damage instead.
- Small amount: A grain-of-rice amount is enough. Excess can get into the eyes and irritate.
- Order: Generally apply after serum and before cream.
- Area: Apply along the orbital bone just below the eye. Be careful not to touch the eyelid or the mucous membrane right under the eye.
Once eye-area aging progresses, it's hard to reverse. Consistent moisturizing and sun protection from your early 20s alone can sufficiently slow aging.
