Before a laser treatment begins cooling the skin is a scientifically mandated step—it is a foundational principle of laser safety. Laser energy is intended to focus on specific structures in the skin, including melanin in follicles and vascular lesions, but it can also impact the surrounding tissue. In the absence of adequate thermal protection, the upper layers of the skin, студии лазерной эпиляции the superficial epidermal cells, are at risk of overheating, which can lead to burns, blistering, or long-term pigmentation changes.
Cooling works by lowering the temperature of the skin’s surface just before and during laser exposure. This creates a heat barrier that protects the epidermis while allowing the laser energy to reach its target to reach its intended target. Think of it like placing a cold spoon on your eyelid before touching something hot—the cold layer acts as a heat sink and prevents damage.
There are several methods used to cool the skin. Some devices use chilled air or cryogen sprays that instantly lower skin temperature. Others use pressure-assisted cooling, where a thermally conductive surface is applied to remove excess warmth. Even built-in cooling systems in laser handpieces use conductive materials to keep the tip consistently cool during treatment.
The timing of cooling is essential. If applied too early, the skin may warm up again before the laser fires. If applied after the pulse begins, there is no safeguard. Modern systems are electronically synchronized to cool the skin milliseconds before the laser pulse, ensuring full efficacy alongside enhanced patient safety.
Research has shown that thermally protected epidermis experiences lower pain scores, minimized complications, and quicker return to normalcy. Patients report noticeably milder procedural pain during procedures, which enhances patient experience and allows for higher laser settings when needed—leading to superior clinical outcomes.
In essence, cooling is a non-negotiable component. It is a evidence-based protective strategy that makes laser treatments safer without compromising potency. Every successful laser procedure relies on this delicate balance between focusing therapeutic energy and shielding the skin from unintended harm.
