Soft Pulse Light For Skin Rejuvenation in Bangkok

What is SPL-F (Square Pulse Light – Facial)?

SPL-F is a next-generation broad-spectrum light skin rejuvenation treatment designed to improve overall skin clarity, brightness, and tone without downtime.

Instead of using a single laser wavelength, SPL delivers filtered multi-wavelength light in very controlled square pulses. This allows the energy to gently target multiple skin concerns at the same time while protecting surrounding skin.

Because the energy is evenly distributed, the treatment is comfortable and safe for all skin types.

​

How it works

The light energy penetrates the upper layers of the skin and is selectively absorbed by pigment (melanin) and tiny blood vessels.

This produces three biological responses:

1. Breakdown of excess pigment – dark spots gradually lighten

2. Reduction of redness and inflammation – skin tone becomes more even

3. Stimulation of collagen activity – skin becomes smoother and more radiant

The body then naturally removes the treated pigment over the following days, revealing clearer skin.

​

What SPL-F treats

SPL is not just a “brightening” procedure — it is a full skin quality treatment.

Pigmentation

• Sun spots

• Freckles

• Dull skin tone

• Uneven complexion

• Post-acne marks

Redness

• Facial redness

• Sensitive skin

• Broken capillaries

• Rosacea-like flushing

Skin quality

• Enlarged pores

• Rough texture

• Early fine lines

• Tired or aging skin

Acne-related

• Inflammation

• Red acne marks

• Oil imbalance

• Helps reduce future breakouts

​

Why skin looks brighter after SPL

Many people think SPL “whitens” skin — it doesn’t bleach the skin.

Instead, it removes things that block light reflection:

• excess pigment
• redness
• inflammation
• uneven texture

When those are reduced, the skin reflects light more evenly — this is why patients notice a clear, glowing, glass-skin appearance.

​

Collagen Stimulation & Skin Renewal

In addition to brightening the skin, SPL-F gently heats the deeper dermal layer, which activates fibroblast cells responsible for producing collagen. As new collagen forms over the following weeks, the skin gradually becomes firmer, smoother, and more refined. Patients often notice improved texture, softer fine lines, and tighter-looking pores. This is why results continue to improve after each session — SPL-F is not only correcting pigment and redness, but also helping the skin repair and strengthen itself from within for healthier, longer-lasting skin quality.

​

What the treatment feels like

Patients feel warm flashes of light with a mild snapping sensation.
Most patients tolerate it very easily and anesthesia is usually not required.

Treatment time: about 15–25 minutes

​

Downtime

• Mild pinkness for 1–4 hours

• Occasional slight warmth

• You may wash your face the same day

• Makeup can usually be applied the next day

Pigmented spots may temporarily appear slightly darker before fading.​

​

Who is a good candidate?

SPL-F is ideal for:

• Dull or uneven skin

• Patients not ready for aggressive lasers

• Sensitive skin types

• Maintenance after laser treatments

• People wanting regular “skin conditioning”

​​

It is commonly used as a monthly skin maintenance treatment.

Summary

SPL-F is a gentle, non-ablative light rejuvenation procedure that improves pigmentation, redness, pores, and overall skin clarity — giving healthier, clearer, and more radiant skin with no downtime.
