Let's Learn About Pico Laser

If you've been navigating the world of skin treatments, you've likely come across the term "pico laser." It's one of the most talked-about technologies in medical aesthetics — and for very good reason. But what exactly is it, how does it work, and is it right for you?

What Is Pico Laser?

Pico laser — short for picosecond laser — delivers ultra-short bursts of energy to the skin in trillionths of a second. To put that in perspective: a picosecond is one trillion times faster than a second. This speed is what sets pico laser apart from older nanosecond lasers, which were already considered fast by previous standards.

Because the pulses are so brief, the laser creates a photomechanical effect rather than a purely thermal one. This means it shatters pigment particles and stimulates the skin through pressure and vibration rather than heat — resulting in significantly less tissue damage and downtime.

What Can Pico Laser Treat?

Pico laser is remarkably versatile. At Cleanse Aesthetics, we use it to address:

Hyperpigmentation and melasma

Sunspots and age spots

Post-inflammatory pigmentation (PIH) from acne

Tattoo removal (all ink colours, including notoriously resistant blues and greens)

Fine lines and textural concerns

Overall skin brightening and tone evening

Why Winter Is the Best Time to Start

Here in South Africa, winter brings lower UV intensity and cooler temperatures — two conditions that are ideal for laser treatments. Post-treatment skin is more photosensitive, and reduced sun exposure during the winter months means a faster, safer healing process and better long-term results.

Starting your pico laser journey in winter also gives your skin time to complete the recommended treatment course and fully resolve before the high-UV summer months arrive.

What to Expect

Most clients describe the sensation as a series of quick, sharp snaps against the skin — similar to a rubber band flick. Treatment time ranges from 15 to 45 minutes depending on the area. There is minimal downtime: some redness and mild swelling for a few hours to a day is normal, and most clients return to their daily activities immediately.

Visible improvement is typically noticed after two to four sessions, with optimal results after a full course of six to eight treatments spaced four weeks apart.

Is Pico Laser Safe for All Skin Tones?

One of the most significant advantages of pico laser is its safety across a wide range of skin tones, including deeper melanin-rich complexions that have historically been more challenging to treat with laser technology. The reduced thermal damage means a lower risk of post-inflammatory hyperpigmentation — a key concern for darker skin types.

That said, a proper consultation and skin assessment is always essential before any treatment. At Cleanse Aesthetics, we tailor every session to your unique skin profile.
