Frequently Asked Questions

PRODUCT

How does Sulbi Sha work?

It combines three therapies: heat, cooling, and microcurrent to boost circulation, reduce puffiness, and tone facial muscles. The result is smoother, more lifted, and glowing skin.

Is it safe for all skin types?

Yes. Sulbi Sha is designed to be gentle and effective on all skin types, including sensitive skin. The heat, cooling, and microcurrent levels stay within comfortable, dermatologist-approved ranges.

When will I start seeing results?

Most users notice an immediate depuffing and glow after the first use. With consistent use, skin tone and contour visibly improve within one to two weeks.

Can I use it every day?

You can use it daily. Most people use it 3–5 times per week as part of their skincare routine for the best results.

How does it compare to a traditional gua sha?

Traditional gua shas rely only on manual massage. Sulbi Sha adds technology through heat, cooling, and microcurrent to enhance results in less time.

How do I clean it?

After each use, wipe the stainless steel edge with a soft damp cloth and mild soap. Avoid submerging the device in water.

Can I travel with it?

Yes. It is lightweight, compact, and TSA friendly, making it easy to maintain your routine wherever you go.

How long will the device last?

With regular use and basic care, Sulbi Sha is built to last for years. It also includes a one-year limited warranty for added peace of mind.
