Rosacea Treatment Options: Medications, Topicals, and Laser Therapy

This is a follow-up to an earlier post on facial flushing and rosacea. Here I'll go into more detail about specific treatment approaches.

Rosacea Treatment

(1) Behavioral Modification

The most important step for every patient is behavioral modification — avoiding the triggers that worsen flushing.

If hot or spicy foods trigger flushing, those foods should be avoided. Rigorous sun protection is essential, and sudden changes in environmental temperature should also be minimized.

(2) Medical Treatment

Both topical agents (creams/gels) and oral medications such as antibiotics can be used for rosacea. In most cases, redness tends to improve within a few weeks.

- Topical Agents

a. Agents with anti-inflammatory + antibiotic effects:

: metronidazole (Rozex), ivermectin (Soolantra) (not currently available in Korea)

b. Agents that reduce cathelicidin:

: azelaic acid

c. Alpha-agonist agents (vasoconstriction; used for flushing and blushing associated with rosacea; used as maintenance therapy):

: brimonidine (Mirvaso gel)

With alpha-agonists, the blood vessels remain in a constricted state after 2–3 months of use. The gel is applied once daily for 2–3 months continuously.

- Oral Medications

a. Metronidazole, doxycycline, isotretinoin

(Isotretinoin is used when sebum production is high and inflammation is present.)

b. In cases of emotional flushing, a beta-blocker may also be prescribed.

(3) Laser Treatment

- Repeated sessions are required.

- Even after significant improvement in redness, a sufficient total number of treatments is necessary.

- Periodic treatment is needed to eliminate newly formed capillaries.

- These lasers target capillaries in the dermis. The laser energy is absorbed by oxyhemoglobin, raising the temperature of the capillary wall and ultimately destroying the capillary.

- Lasers commonly used for flushing and rosacea include:

a. Long-pulsed Nd:YAG laser

b. IPL (strictly speaking, not a laser, but widely used)

c. Long-pulsed Alexandrite laser

d. PDL (pulsed dye laser)

e. Copper-bromide laser (yellow laser)

- When inflammation is present along with papules and pustules, needle radiofrequency (RF) or a 1550 nm erbium glass fractional laser may also be used.

This has been a brief overview of facial flushing and rosacea.

Above all, the key point is that rosacea treatment must be carried out consistently over a long period of time. Even after symptoms improve, ongoing maintenance treatment remains necessary.
