Hello, in the previous post I introduced Excel V. For those of you who are worried because dark spots and facial redness have become very noticeable, and your skin seems to have lost its elasticity, the laser Bellevue recommended was Excel V. Many people have seen the effects of this laser. It is popular because it can address three difficult concerns—pigmentation, blood vessels, and elasticity—with a single device, and with great precision. So today, shall we take a look at vascular dilation? Why is it that some people have healthy blood vessels, while others have more visible facial vessels that stand out? There must be a reason.

There are many causes of vascular dilation and facial redness. If we look at them broadly, they can be divided into five categories.

Among them, I’d like to talk a little more about steroids. This was a case of someone close to me recently. After high-dose steroid therapy prescribed for the treatment of facial paralysis, this person developed problems with their face. They had no choice but to take high-dose steroids. While this prescription is essential for reducing nerve inflammation, it can have an impact on the skin that feels like a true “storm.” From the symptoms they described, it was highly likely to be medically known as steroid-induced acne.

They asked whether oral medication or topical medication is more dangerous, and my answer was, “For the whole skin, oral medication is overwhelmingly more destructive; for localized structural changes, topical medication is more persistent.” Depending on a person’s constitution and health condition, it may pass with little effect on the skin.... In this person’s case, unfortunately, their previously healthy skin suddenly became severely damaged. Recovery also took quite a long time afterward, and even now they still experience discomfort such as very sensitive skin and frequent redness.

Oral steroids are a “hormonal bombardment” that hits the whole body

The steroids usually prescribed for facial paralysis are from the prednisolone class, and for about the first week, a very high dose is taken. The skin problems that occur at this time are due to systemic hormonal disruption. High-dose steroids directly stimulate the sebaceous glands, causing sebum production to surge dramatically in a short period of time. My acquaintance described it as “turning into a sea squirt,” which was because the suddenly increased sebum clogged pores, causing both comedones (small bumps) and pustular inflammation to appear across the face at the same time. In addition, because steroids suppress strong, spreading inflammation, they also lower immunity. As a result, it becomes an environment where bacteria and Demodex mites in the skin pores can multiply easily, so even skin that usually has no trouble can flare up in an instant. Of course, since this is a problem caused by medication, symptoms gradually improve once the medication is stopped, but the scars and marks left behind during that process can be severe enough to require laser treatment (such as Excel V), so this person also had to receive follow-up treatment like that.

Then what about topical (applied) steroids?

Compared with oral medication, topical medication has fewer systemic side effects, but it is more frightening in that it fundamentally destroys the skin structure of the treated area. If steroid ointment is applied for a long time, collagen production in the dermis stops, the skin becomes paper-thin, stretch marks (striae) may appear, and telangiectasia, with blood vessels clearly visible, can remain permanently. If you look at elderly people who have applied medication for a long time because of knee pain, you can see that the skin on the knees has become very thin. The same symptoms appear on the face as well. In addition, the skin loses its ability to regulate blood vessel activity, so even a slight change in temperature can make the face burn red and not calm down easily. This is much more difficult and takes far longer to treat than oral medication.

Which is more dangerous?

Comparison itemOral (taken by mouth)Topical (applied)
Nature of riskAcute, explosive (systemic skin trouble)Chronic, structural (skin atrophy, vascular dilation)
Recovery potentialRelatively good recovery after stopping the medicationVery difficult to recover; risk of permanent damage
Main symptomsSteroid acne, swellingFacial redness, thinning skin, visible fine blood vessels

In conclusion, oral high-dose steroids taken for a short period to treat facial paralysis, like in my acquaintance’s case, can cause a very shocking and distressing skin flare-up right away, but if the medication is stopped and appropriate care is provided, it can be reversed. On the other hand, topical steroids bought at a pharmacy and applied to the face for months without much thought can damage the skin’s “foundation” (the dermis) in an irreversible way, so in the long term they can be considered more dangerous.

Actually, taking steroids for facial paralysis treatment should never be stopped on your own, because nerve recovery is the priority. Skin flare-ups are painful, but preventing nerve damage comes first. Instead, if you manage the dilated blood vessels and inflammatory marks with a laser such as Excel V during or right after taking the medication, and combine that with skin booster procedures that help strengthen the skin’s immunity, you can restore the damage left by steroids much faster. In cases like this, when the oil glands have become sensitive because of the medication, you should absolutely not squeeze the inflammation by hand, and once the medication course ends, getting professional soothing care is the way to prevent scarring.

The power of Excel V to complete clear skin

Excel V, which combines the power to remove pigmentation, the precision to target blood vessels, and the softness to improve elasticity, is, I believe, the most reliable finishing touch for those who want clear, transparent skin. If your face stays red and the blood vessels are too visible, making it difficult to go out bare-faced without makeup, please remember Excel V.

Recommended for the following people

  • Those who have both dark spots and redness, making their skin look dull and dirty
  • Sensitive skin with fine blood vessels around the nose or visible fine vessels
  • Those whose pigmentation quickly returns despite frequent toning treatments
  • Those who want to improve skin texture at once without irritation
