"My lips are so dry

that even if I keep applying lip balm,

it doesn’t help much.

There’s also a lot of flaking,

and people around me say I look haggard because of it..."

When I talk with people who come in because they’re worried about dry lips,

many say things like:

"My lifelong wish is to try matte lipstick at least once"

"I’ve bled several times from picking at lip flakes"

a lot.

Because they’re so far from having moist lips, they seem to have been living with this frustration.

For restoring moisture to the lips, skin booster procedures such as Rejuran that include hydration can help.

Today, we’ll take a detailed look at the principles and effects of applying Rejuran to the lips, which has wrinkle- and dryness-improving effects, as well as the pain concerns many people worry about.

Principles and Effects of Lip Rejuran Treatment

You may have heard a lot about getting Rejuran on the face, but many people still find the idea of getting it on the lips unfamiliar.

So first, let’s look at what effects Rejuran can have when applied to the lips.

Rejuran is a treatment that helps with dryness and fine lines on the lips.

Unlike other areas, the lips do not have sebaceous glands, so they are originally a part of the face that tends to become dry easily.

On top of that, the skin layer is thin, making it sensitive to external irritation, and since it keeps moving while eating and speaking, it is an environment where dryness and wrinkles can easily form.

If Rejuran is injected into a shallow layer about 1–2 mm beneath the skin of the lips, it stimulates and activates fibroblasts in the lip skin, causing them to produce components that make up the skin, such as collagen, elastin, and hyaluronic acid.

Then, as collagen builds up, lip wrinkles become less visible, and the ability to retain moisture is restored, helping relieve dryness.

To use an analogy, it is similar to not just watering dry soil, but making the soil itself more fertile.

Lip balm or lip masks can only help moisturize the surface, but Rejuran is closer to helping the lip skin hold onto moisture and maintain it on its own.

And sometimes, when people hear about lip treatments, they assume it is filler. But it is different.

Rejuran is a process that induces skin regeneration by encouraging the body to produce helpful skin components such as collagen and elastin on its own.

Filler, on the other hand, is a treatment focused solely on "volume," used when you want thin lips to look fuller or want to change the shape of the lips.

How Can Pain Be Reduced?

To be honest, Rejuran is a treatment that hurts if you simply get it without any measures. In particular, the lips are an area with many nerve endings, so they may feel even more sensitive.

There are two main reasons why Rejuran is painful.

First, the viscosity of the Rejuran formula itself creates pressure during injection.

Also, to see the effect, it must be injected into the shallow dermal layer, and the shallower the injection, the more pain is felt.

That said, this does not mean it has to be painful. With a product called Rejuran HB PLUS, it has become possible to reduce concerns about pain.

HB PLUS contains lidocaine, a local anesthetic, so the numbing effect begins as soon as it is injected.

It also reduces pain by about half.

It also contains hyaluronic acid, which lowers the viscosity appropriately, so there is less pressure during injection and, accordingly, less pain.

Standards for pain vary greatly from person to person, so it is really difficult to say exactly how much.

Even in a sensitive area like the lips, there are many reviews saying it felt much more comfortable compared to regular Rejuran.

How Should You Care for It After Treatment?

First, it is best not to touch your lips excessively for about a day.

Also, please avoid hot foods or spicy and irritating foods.

It is best to refrain from smoking or using straws for about a week.

This is because applying strong pressure to the lips or repeatedly pursing them can affect the distribution of the medication.

Today, we looked at the principles and effects of lip Rejuran treatment, as well as ways to reduce pain.

If you have a lot of flaking on the lips or many vertical lines, Rejuran may help when used appropriately.

Usually, about 1 cc is injected evenly across the entire lip area where needed, including the upper lip, lower lip, and corners of the mouth.

However, even within the lips, there are cases where dryness is especially severe in the upper lip, lower lip, or a specific area, and those areas need more focused care.

So I recommend getting treatment at a place that carefully checks which areas need more care and provides treatment tailored to you, and I’ll wrap up here.
