How to identify your skin type — the 30-second test at home

The most common reason products "don't work" isn't the product — it's that they were bought for the wrong skin type. A rich cream on oily skin clogs pores. A light gel on dry skin hydrates nothing. Learn your type first, then buy.

The bare-face test (30 seconds + 1 hour wait)

1. Wash your face with a gentle cleanser, pat dry and apply nothing.
2. Wait 1 hour — go about your day, don't touch your face.
3. Look and feel:

• Tightness everywhere, skin looks dull or flaky → dry
• Visible shine on forehead, nose, chin (T-zone) and cheeks → oily
• Shine only in the T-zone, cheeks normal or dry → combination
• Redness, burning or itching for no reason → sensitive
• Neither tightness nor excess oil → normal (you won the lottery)

Quick version: press blotting paper (or a clean tissue) on your forehead and cheeks after the hour. Oil marks everywhere = oily. T-zone only = combination. Nothing = dry/normal.

Careful: dry ≠ dehydrated

This is the biggest trap. Dry is a type — your skin produces little oil. Dehydrated is a condition — your skin lacks water, even if it's oily. If your face gets shiny AND feels tight at the same time, you have dehydrated skin — and heavy "dry skin" creams will make it worse.

One starter product per type

Oily: SKIN1004 Poremizing Fresh Ampoule — a light centella ampoule that balances oil without stripping. Oil isn't fought with dryness — it's balanced.

Dry: TIRTIR Ceramic Cream — a rich ceramide cream that rebuilds the barrier and holds moisture for hours. The "ceramic" structure locks water in.

Sensitive / redness-prone: Dr. Althea 345 Relief Cream — formulated specifically for reactive skin: calms redness, strengthens the barrier, zero fragrance.

Combination: Haruharu Wonder Black Rice Probiotics Barrier Essence — a probiotic essence that hydrates without weighing down the T-zone and nourishes dry cheeks. One product, two zones, zero conflict.

Dehydrated: COSRX Snail 96 Essence — 96% snail mucin, the global leader in deep hydration. Light, oil-free, penetrates where creams can't reach.

How often does your type change?

More than you think. Seasons, hormones, stress and travel shift it — combination skin in summer easily turns dry in winter. That's why a routine isn't "forever": re-test every 3–6 months.
