Understanding Laser Treatments: How Do They Work on the Skin?

Laser Treatments by DIXIS MEDISPA in LA

Laser treatments have revolutionized the world of dermatology, offering effective solutions for various skin concerns, from acne scars to unwanted hair. But how do these beams of light work their magic on our skin? Let’s explore the fascinating world of laser treatments, their mechanisms, applications, and what to expect during and after a laser procedure.

The Basics of Laser Technology

Laser, which is short for Light Amplification by Stimulated Emission of Radiation, harnesses the power of highly concentrated and precisely controlled light energy. Lasers emit a single wavelength of light, allowing for remarkable precision in various applications. This precision is essential for understanding how lasers work on the skin and their impact on dermatology.

Laser-Tissue Interaction

When a laser is directed at the skin, several important processes come into play:

Absorption of Light:

Different components of the skin absorb specific wavelengths of laser light. For instance, melanin (the pigment responsible for skin and hair color) absorbs light in the infrared spectrum, while hemoglobin (the protein in blood) absorbs certain visible light wavelengths. The selective absorption of light is key to targeting specific skin concerns.


Once the laser energy is absorbed by the skin, it is converted into heat. This controlled heating can have various effects, depending on the treatment’s goal. For instance, in hair removal, the heat damages the hair follicle, inhibiting future hair growth. In skin resurfacing, it stimulates collagen production and encourages new, smoother skin growth.

Common Applications of Laser Treatments

Laser treatments find diverse applications in dermatology, addressing a range of skin concerns. These common applications include:

  • Hair Removal: The laser treatment targets hair follicles, inhibiting hair regrowth by damaging the follicle’s ability to produce hair. It offers a long-term solution for unwanted hair on various body areas.
  • Skin Resurfacing: Laser skin resurfacing treats wrinkles, fine lines, acne scars, and uneven skin tone. Increasing collagen production and stimulating new skin growth will result in smoother, rejuvenated skin.
  • Tattoo Removal: Lasers break down tattoo ink particles into smaller fragments, allowing the body’s natural processes to gradually eliminate them. Usually, it takes several sessions to remove a tattoo completely.
  • Acne Scar Treatment: By encouraging collagen remodeling and minimizing the visibility of scar tissue, laser therapy can reduce the appearance of acne scars. It’s a valuable option for individuals seeking smoother skin texture.
  • Skin Tightening: Some laser treatments are designed to tighten loose or sagging skin. They work by stimulating collagen production, leading to firmer and more youthful-looking skin.
  • Pigmentation and Sunspot Removal: Lasers can target and break down excess melanin in the skin, effectively reducing the appearance of pigmentation issues like sunspots, age spots, and melasma.
  • Vascular Lesion Treatment: Laser therapy is used to treat vascular lesions like spider veins and port-wine stains by targeting the blood vessels responsible for these skin conditions.
  • Wrinkle Reduction: By encouraging collagen formation and skin tightening, some laser treatments, such as fractional laser therapy, are successful in minimizing the appearance of wrinkles and fine lines.
  • Scar Revision: Lasers can help improve the appearance of surgical scars, injury scars, or other types of scars by encouraging the formation of smoother, more even skin.
  • Skin Rejuvenation: Treatments for laser skin rejuvenation, such as fractional laser resurfacing, are used to enhance the skin’s overall texture and tone while minimizing aging and photodamage symptoms.

These diverse applications demonstrate the versatility and effectiveness of laser technology in addressing various skin concerns. The choice of the specific laser treatment depends on the individual’s unique needs, skin type, and desired outcomes, making it essential to consult with a qualified dermatologist for personalized recommendations and guidance.

What to Expect During and After a Laser Procedure

Understanding what to expect during and after a laser procedure is essential for individuals considering these treatments. While experiences may vary depending on the specific laser procedure and individual factors, here’s a general overview:

Before the Procedure:

  • Consultation: You’ll typically have a consultation with a dermatologist or trained professional to discuss your goals, assess your skin type, and determine the most suitable laser treatment for your needs.
  • Preparation: Before the procedure, your skin may be cleaned to remove any makeup, lotions, or oils. To lessen discomfort during the procedure, a topical numbing cream may occasionally be used.

During the Procedure:

  • Protective Eyewear: To protect your eyes from the laser light, you will be given protective eyewear.
  • Treatment: The dermatologist or technician will use a handheld laser device to target the specific area of concern on your skin. During the procedure, you may feel sensations such as warmth, tingling, or mild discomfort, but it is typically manageable and temporary.

After the Procedure:

  • Immediate Effects: Depending on the treatment, you may notice immediate changes in your skin, such as reduced pigmentation, smoother texture, or the absence of hair. However, these effects can vary.
  • Skin Sensation: After the procedure, your skin may feel slightly red, swollen, or sensitive. These side effects are typically transitory and can be managed with post-procedure care.
  • Post-Procedure Care: Dermatologists provide specific post-procedure care instructions. These instructions may include applying moisturizers or ointments, avoiding sun exposure, and refraining from certain skincare products for a specified period.
  • Recovery Time: Depending on the type and intensity of the laser treatment, the recovery period may differ. Some treatments may require minimal downtime, while others may necessitate several days of recovery.
  • Follow-up Sessions: Depending on the treatment plan and desired outcomes, you may require multiple laser sessions spaced over several weeks or months to achieve optimal results.
  • Long-Term Results: Many laser procedures offer long-lasting results, but following recommended skincare routines and sun protection is essential to maintain these results over time.
  • Consultation for Concerns: If you experience any unusual or severe side effects after the procedure or have concerns about the results, it’s crucial to contact your dermatologist promptly for guidance.

Laser procedures can provide effective solutions for various skin concerns, but the experience during and after the treatment can vary. Understanding what to expect, following post-procedure care instructions, and maintaining open communication with your dermatologist is key to achieving the desired outcomes while ensuring your safety and comfort.
