Intense Pulsed Light Therapy for Photodamage Reversal

Using an intense pulsed light (IPL) device with bandpass filters to provide cosmetic treatments equivalent to specific laser wavelengths. The filters block most IPL light except a narrow range that matches the absorption spectrum of the target chromophore. By matching absorption, it allows IPL devices to simulate laser treatments without needing a separate laser. The filters can be swapped to provide different laser equivalents with a single IPL handpiece.

Using selective band pass filters with intense pulsed light (IPL) devices to provide equivalent cosmetic treatment as specific laser wavelengths. The filters block most IPL light except a narrow range that matches the absorption spectrum of the target chromophore. For example, a 525-585 nm filter provides IPL treatment similar to a 532 nm laser for vascular lesions. By selecting filters with absorption coefficients matching lasers, IPL can provide laser-equivalent treatment without the limitations of removing too much light.

Phototherapy device for treating and improving skin conditions that can evenly treat the skin from the epidermal layer to the subcutaneous layer. The device uses a combination of LEDs and an optical filter. It has a wide-spectrum white light LED to irradiate visible light. Additionally, it has narrow-spectrum LEDs emitting specific wavelengths. An optical filter selectively transmits light above 495nm from the white LED and blocks lower wavelengths. This allows treating multiple skin layers using the wide-spectrum white LED while avoiding harmful blue light from the narrow-spectrum LEDs.

Light-based dermatological treatment device that can repeatedly pulse a flashlamp to emit therapeutic light energy without using a charged capacitor. The device has a switching power supply with a pulse-actuated circuit and control circuit. The control circuit modifies the pulse duration based on AC line voltage to ensure the flashlamp emits enough light. This allows smaller, lighter, and cheaper devices compared to capacitor-based systems. The control circuit also compensates for low voltage sag conditions. The flashlamp is selected to emit the desired fluence range for treatment.

A treatment device for non-invasive treatment of skin conditions like discoloration, acne, wrinkles, blood vessels, cellulite, and scars. The device uses multiple light sources with varying wavelengths to optimize treatment effectiveness. It includes incoherent light sources like flash bulbs and electronic flashes, as well as coherent sources like lasers. Filters move across the light sources at a speed to match tissue absorption changes. This allows constant energy levels despite varying skin pigmentation. The device sequences and pulses the lights for treatments like hair removal, wound healing, and collagen production.

Combining light therapy with topical agents to improve skin conditions and outcomes. The method involves sequential steps of light treatment followed by application of a topical agent between sessions. The topical agent modulates skin cell products like collagen, elastin, melanin, and energy levels. By using agents to maintain and enhance these factors between light sessions, it synergizes with the light treatment to further improve skin appearance, texture, and health.

Apparatus for treating skin using pulsed optical radiation that delivers a series of discrete spaced pulses instead of a single pulse to avoid overheating and damage. The pulse modulator controls pulse width and spacing to flatten the heat pulse envelope at the treatment site. This prevents excessive temperature spikes and allows effective treatment without cooling or gels. The modulator delivers a train of discrete pulses over time to provide the required dose.

Efficiently removing wrinkles and rejuvenating skin using pulsed light to heat collagen below the epidermis while cooling the outer layers to avoid damaging the skin. The method involves applying a cool gel to the skin before treatment and then pulsed light to heat the collagen and shrink wrinkles. The pulsed light is delivered using a flexible or rigid light guide. The cooling protects the epidermis from overheating. This allows targeted collagen shrinking without full epidermis removal.

Closed-chamber device for dermal treatment using intense pulsed light (IPL) that eliminates the need for external cooling methods. The device has an applicator head with a sealed compartment containing the IPL source. The compartment has an opening for treating the skin. Inside the compartment, a built-in cooling mechanism, like an air fan or pipe connection, provides active cooling to prevent overheating. This allows the device to deliver IPL treatment directly to the skin without external cooling methods like gels or liquids. The sealed chamber also prevents contamination. The compartment opening has a contact edge that touches the skin and leaves a mark to guide positioning. The edge also creates a gap between the filter and skin to prevent overheating.

Non-ablative photorejuvenation technique for tightening skin and promoting collagen production without damaging the epidermis. The technique involves precooling the skin, applying low-energy pulsed light with dynamic cooling during treatment, and repeating the low-energy treatments over multiple sessions. By cooling the epidermis while heating the dermis, it prevents excessive epidermis temperature rise that could damage the skin. The lower energy pulses allow more treatments without epidermis damage. This gradual heating of the dermis promotes collagen production and tightening of the skin.

A multi-broadband pulsed light emitter (MPLE) for effective dermatological treatments with reduced pain and better penetration compared to existing pulsed light sources. The MPLE has a unique light source design that concentrates the energy in the middle of the lamp and emits homogeneous, concentrated light over a large focal spot size. This allows high energy delivery with low epidermal heating. The MPLE also uses chopped pulsed light modes, cooling, and controlled parameters to further enhance treatment effectiveness and safety.

Superficial tissue heating method and device to improve skin texture and reduce lines without deep tissue removal. The method involves heating the upper layers of skin to a specific temperature range, around 55-60°C, that causes collagen shrinkage without damaging it. The device uses controlled pulsed energy delivery to heat the skin surface to this temperature for a brief period. The heat-induced collagen contraction tightens the skin without removing it, reducing lines and improving texture. The shallow heating avoids issues like infection, extended recovery, and pigmentation changes compared to deep resurfacing techniques.

Cosmetic treatment method for rejuvenating aged skin using specific wavelengths of light to stimulate skin cells without surgery. The treatment involves two courses of light therapy separated by a week. The first course is with near-infrared light for 3-14 days to stimulate inflammation and wound healing. The second course is with red light for 1-35 days to promote collagen production. The light therapy sessions are 2-60 minutes long at intensities of 1-150 mW/cm2.

Non-surgical method and system to improve the appearance of skin using pulsed light from solid state sources without damaging the skin. The method involves illuminating skin areas with pulsed visible light from sources like diodes, at intensities that produce cosmetic effects like tanning, wrinkle reduction, hair removal, or treating medical conditions, without ablating the basal layer. The pulsing modes, like banked, overpulsed, and superpulsed, are controlled to raise dermal temperatures. A light guide delivers the pulsed light from the sources to the skin.
