When skin condition has broken down, dryness may keep recurring, or oil may build up while the inside still feels tight. At the same time, the overall skin texture can also look rough and dull.

These changes tend to appear more easily as external stress accumulates or daily routines become irregular. When the issue is not just a single factor but several overlapping factors, care that helps improve the dermal layer from within can be useful.

Among methods that can directly deliver active ingredients into deeper layers, Sangmu Station Rejuran is an effective treatment for activating the skin’s self-repair ability and improving overall skin condition.

In this post, we will look at this solution and organize the common questions that come up afterward, including whether washing your face, using sunscreen, and wearing makeup are possible.

Delivery of PN material into the dermal layer

This method involves injecting PN (polynucleotide) extracted from salmon DNA into the dermal layer.

It works in a way that activates the skin’s self-repair ability, and you can expect it to be effective in improving damaged skin.

Also, unlike methods that simply add moisture to the surface, this is care that improves the deeper dermal layer, so it can effectively improve dryness and tightness felt from within.

You may also experience a variety of effects, such as easing breakouts, strengthening the skin barrier, normalizing the oil-moisture balance, and reducing pores and fine lines.

When can you wash your face after Rejuran at Sangmu Station?

After receiving this treatment, it is necessary to avoid washing your face on the same day. Because this is a solution administered through injections, the treated area is temporarily sensitive, so it is important to minimize external irritation.

In particular, even if it is not visible, the skin may react to minor irritation on the same day, so it is helpful to reduce physical contact as much as possible.

In addition to not washing your face, it is also better to avoid the habit of touching the area with your hands.

Usually, washing your face is possible starting the next day, but even then, it is important to cleanse gently rather than rubbing as you normally would.

When using cleansing products, choose a low-irritation type, and after building up enough foam, finish with light rolling motions to help reduce the burden on the skin.

Makeup is also possible starting the next day, but at this stage, it is helpful to keep it light rather than using heavy coverage.

Also, after applying makeup, you need to pay attention to the cleansing process as well. To avoid repeated strong irritation while removing it, it is necessary to manage the skin in a way that reduces irritation by using gentle products.

Can you use sunscreen after Rejuran at Sangmu Station?

Sun protection is one of the important parts of aftercare. To reduce external irritation and protect the skin condition, it is necessary to consistently use sunscreen when going out.

However, since minimizing irritation is the top priority on the same day, it is better to start using it the next day, just like with face washing and makeup.

At this time, if you use a hat or parasol along with sunscreen, you can block UV rays more effectively, so please keep this in mind as well.

Lastly, I will also mention other points to keep in mind.

✔️Avoid alcohol and smoking for about one week

✔️Avoid saunas, public baths, and strenuous exercise as well

If these daily care steps are followed together, better changes can be expected.

Thank you for reading this long post.
