The morning after popping a pimple,

if you're wondering whether to put on DuoDERM or not

Check this before reading

Q. If you put on DuoDERM, won't it trap the fluid

and make it heal worse?

A. This is something many people misunderstand,

DuoDERM doesn't trap the exudate;

it absorbs it and turns it into a gel.

That gel itself creates a healing environment.

Q. Then does the healing speed really

differ that much from a regular bandage?

A. Compared with dry dressings, it can be up to 2x faster.

This isn't just a marketing phrase;

it's a figure based on moist wound healing theory.

DuoDERM, they all look like the same kind of bandage, right?

But actually,

DuoDERM is a moist dressing made with

hydrocolloid ingredients.

Unlike regular adhesive bandages or gauze,

DuoDERM absorbs exudate

and turns it into a gel

creating a moist barrier over the wound.

That's the key difference.

Why does the same wound

heal faster on the side with DuoDERM applied?

Key points of this article

DuoDERM, a hydrocolloid dressing,

absorbs exudate and gels it,

creating a moist environment and

increasing healing speed compared with regular dry dressings

by up to 2x.

Here's the key.

DuoDERM, a hydrocolloid dressing,

absorbs exudate and gels it,

creating a moist environment and, compared with regular dry dressings,

increasing healing speed by up to 2x.

Last month, a 41-year-old client had a deeply squeezed pimple mark along the jawline

that kept scabbing and coming off for two weeks.

Every time the scab dried while using a regular bandage,

epithelial regeneration was interrupted.

After switching to DuoDERM and changing it every 3 days,

the epidermis had almost closed by day 6.

In a moist environment, epidermal cells move smoothly over the wound

without a scab and cover it.

This principle has already been proven by clinical data.

Dr. Wi Young-jin's key summary

DuoDERM does not block exudate; it turns it into gel

and creates a moist layer.

Thanks to this moist layer, it skips the scab stage

and the epidermis covers faster.

However, do not use it on infected wounds.

Is my wound in a condition where DuoDERM can be applied?

A state where exudate is slightly visible, like right after popping a pimple,

is when DuoDERM works best.

On the other hand, if you leave DuoDERM on a pus-filled pimple,

the inflammation may spread to the surrounding area,

so be careful.

Frequently asked questions we often hear in the clinic

Q1. It has turned white and swollen—should I remove it?

Whitening and swelling are normal signs

that gel formation is happening well.

Usually, changing it once every 2–3 days, when the edges start to lift,

is better for maintaining the moist environment.

Q2. Is it effective for preventing scars too?

Because DuoDERM reduces the scab stage, as a result

post-inflammatory hyperpigmentation (PIH) tends to be less noticeable.

It also has a strong effect in

physically preventing you from touching it with your hands.

Q3. What about UV exposure or makeup?

If you apply makeup over DuoDERM,

the adhesion can weaken and exudate may leak.

Skin right after removing the patch is sensitive, so

it's best to protect it gently

with a physical sunscreen.
