🧪 Oily vs. Dry vs. Sensitive Skin: How to Self-Diagnose

I’m sharing self-diagnosis methods and care points for oily, dry, and sensitive skin types!

Hello, this is Yonsei Bomvit Dermatology.

“I don’t know what type of skin I have.”

This is one of the most common questions we hear from people who come in to discuss skin concerns.

To care for your skin properly, you need to know your skin type accurately.

Today, I’ll organize a simple at-home self-diagnosis method for skin type,

along with care tips for each type.

Oily vs. Dry vs. Sensitive Skin

1️⃣ What type is my skin? Simple self-diagnosis method

✔ After washing your face, wait at least 1 hour without applying anything

The most basic and accurate skin type test is to observe how your skin responds after cleansing.

• Oily skin

Overall shine appears, and pores are visibly noticeable

• You feel oiliness not only in the T-zone but also all over, including the cheeks and chin

• Dry skin

Tightness is severe after washing, and dead skin cells may lift or flake white

• The skin texture feels rough, and makeup tends to cake or lift easily

• Combination skin

The forehead and nose are shiny, but the cheeks feel tight or dry

• The skin condition differs by area of the face

• Sensitive skin

Often feels stinging or burning even without any special irritation

• Easily reacts to temperature changes, masks, cosmetics, and becomes red

✔ You can also use the tissue test

• 2 hours after washing your face, place tissue on your face and check

Oil on the forehead, nose, and cheeks → Oily skin

• Almost no oil → Dry skin

• Oil only in the T-zone → Combination skin

2️⃣ Care points by skin type ✨

✔ Oily skin

• Focus on hydration rather than trying to forcibly remove sebum

• Choose oil-free, non-comedogenic products

• Avoid excessive exfoliation, and use a gentle cleanser

✔ Dry skin

• Apply moisturizer generously, and a mildly acidic cleanser is recommended

• Strengthen moisture care centered on ingredients such as hyaluronic acid, ceramide, and panthenol

• Exfoliate no more than once a week, and be gentle

✔ Combination skin

• A strategy that separates T-zone and U-zone care is needed

• Adjust products with a focus on oil control in summer and moisture in winter

• Use dedicated cotton pads for subtle, area-specific skin care adjustments

✔ Sensitive skin

• Use products with simple formulas and low irritation

• Avoid alcohol, artificial fragrance, and strongly acidic ingredients

• Products containing soothing ingredients such as madecassoside and panthenol are recommended

3️⃣ In these cases, please receive dermatology treatment 📍

• If unusual breakouts or reactions suddenly appear compared to usual

• If your skin easily becomes red and itchy even after trying multiple products

• If your skin texture becomes rough and sensitive no matter how much you moisturize

📌 At Yonsei Bomvit Dermatology, we consider your skin type and propose accurate, customized care and treatment plans.

📖 In closing

If you don’t know your skin type, even the best product can become “a cosmetic that doesn’t suit me.”

First, understand your skin accurately, and then flexibly adjust your care routine depending on the situation.
