Are you troubled by the specks of age spots, acne scars, or patches of dullness on your face? These skin problems, collectively known as "pigmentation," seem to be deeply rooted, difficult to remove even with the best skincare products. They not only affect our appearance but also erode our self-confidence. How should we deal with these stubborn issues? Pico lasers, with their precise and efficient "targeted treatment," are becoming one of the preferred solutions in modern dermatology.
Pigmentation is the color of biological tissues, primarily determined by a pigment called melanin. In humans, melanin gives skin, hair, and eyes their color; it is produced by specialized cells called melanocytes. Factors such as genetics, sun exposure, and hormonal changes can affect melanin production, leading to color changes, such as darker spots (hyperpigmentation) or lighter patches (hypopigmentation).
Pigmentation doesn't appear out of thin air. Its root cause lies in the overactivity of melanocytes deep within the skin, leading to the production of excessive melanin, which then deposits in the epidermis or dermis.
The main causes include:
This is the primary and most common cause. UV rays activate melanocytes, causing them to defensively produce large amounts of melanin, resulting in sunspots, age spots, etc.
Skin inflammation caused by acne, eczema, trauma, or improper skincare can leave brownish-gray marks, known as "acne scars," after healing.
Melasma caused by factors such as pregnancy or oral contraceptives is typically symmetrically distributed on the cheeks.
Some freckles are related to genetics, and as we age, skin metabolism slows down, making it easier for age spots to form.
These pigment particles are like weed seeds buried deep in the soil; traditional methods often fail to eradicate them, which is why pigmentation is so "stubborn."
Picosecond lasers are not a new laser wavelength, but a revolutionary innovation in laser technology. Its core advantage lies in its speed.
1 picosecond = one trillionth of a second. The pulse width (action time) of picosecond lasers reaches the picosecond level, which is 1000 times faster than traditional nanosecond lasers (1 nanosecond = one billionth of a second).
Due to its extremely short action time, it instantly generates extremely high peak energy. Its core mechanism is the "photoacoustic effect." Instead of slowly "heating," it acts like an extremely fine and fast hammer, directly shattering stubborn pigment particles into fine sand-like powder, which is then naturally eliminated from the body through metabolism. The entire process generates very little heat, causing negligible damage to the surrounding skin.
Pigment particles are broken down more thoroughly and are more easily cleared by the body's immune cells.
Minimal thermal damage is produced, significantly reducing the risk of burns and post-inflammatory hyperpigmentation.
Increased clearance efficiency means fewer treatments may be needed to achieve the desired results, allowing beauty salons and clinics to serve more clients daily.
While shattering pigment, the shockwaves of the picosecond laser stimulate deep collagen regeneration, thus providing the added benefits of shrinking pores and refining skin texture while removing pigmentation.
Picosecond laser treatment itself is quick, but post-operative care directly affects the final result and safety.
After treatment, the skin may experience slight redness and a burning sensation. Apply ice immediately to soothe the skin.
Newly formed skin is very delicate. UV exposure can immediately stimulate melanocytes, leading to recurrence or even worsening of pigmentation. High SPF (SPF50+, PA+++) broad-spectrum sunscreen must be used, along with physical sun protection (hats, masks, sun umbrellas).
Use medical-grade repair dressings and moisturizing products to help the skin barrier recover quickly.
Use lukewarm water and a gentle cleanser, avoiding vigorous rubbing.
Within one week after the procedure, avoid using skincare products containing acids (salicylic acid, glycolic acid), retinol, or other irritating ingredients. Suspend exfoliation.
It usually takes 1-2 weeks for the shattered pigment to metabolize. After treatment, the pigmentation may temporarily darken or form a thin scab, which is normal. Do not scratch it，let it fall off naturally.
| Treatment | principle | Advantages | Disadvantages | Suitable symptoms |
|---|---|---|---|---|
| Picosecond laser | Photoacoustic effect, rapidly shattering pigments | Precise and efficient, minimal damage, quick recovery, and skin-rejuvenating. | The price is relatively high | Various stubborn pigmentation spots (sun spots, age spots, freckles, nevus of Ota), acne scars, melasma (special treatment required). |
| Traditional Q-switched lasers | Photothermal effect, nanosecond-level pigment shattering | The technology is mature, effective for clearly defined pigmentation spots, and relatively inexpensive. | Heat damage can cause hyperpigmentation, which has a long recovery period and requires multiple treatments. | Surface, larger granules of pigmentation |
| Intense Pulsed Light （IPL） | Broad spectrum, composite light energy | Improves overall skin tone, redness, and fine hairs; brightens skin tone. | It has weak targeting and limited effectiveness against deep and stubborn pigmentation. | Superficial blemishes, uneven skin tone, overall brightening |
| Chemical skin resurfacing | Acids corrode the epidermis and promote metabolism. | Low price, can improve superficial acne scars and roughness | Multiple treatments are required; it is ineffective for deep pigmentation and may irritate the skin. | Superficial acne scars, dullness |
| Topical skin care products | Inhibit tyrosinase and block melanin production | Routine maintenance, gentle, for prevention and support. | It has limited penetration and is almost ineffective against existing deep pigments. | Prevents pigmentation and helps lighten pigmentation. |
