If you shy away from being in photographs because you are embarrassed or self conscious of acne, then a similar technology that uses light could help you embrace being in the camera’s eye. Light therapy uses two kinds of light to treat acne and the bacteria that causes it. Find out more to see if photodynamic acne therapy might work for you in Manhattan.

Beneath The Surface

Washing your face obviously helps keep it clean, but this only affects the surface of your skin. Red light at certain wavelengths can interact with the skin to get below pores and reach the sebaceous glands that cause excess oil and clog pores. Visible red light heats can shrinks sebaceous glands, which prevents blackheads and whiteheads from forming.

Removing Bacteria

Chemicals in acne bacteria share qualities with blue light that make them resonate at specific wavelengths, and the light heats up the chemicals so that they burst the membranes protecting the acne bacteria.

The vulnerable bacteria is then attacked by oxygen and dies within 48 hours. Teens and young adults will notice results quickly from this treatment while older adults might not see any difference for a week or more.

Just The Right Balance

The same blue light produced by the sun can be harnessed to kill acne causing bacteria, but UV light is not used in this treatment.

This means the blue light does not damage skin. To keep red light from burning the skin, it is used in conjunction with blue light in a pulsating pattern.

Dermatologists have found that photodynamic acne therapy works when using the red light only as much as necessary to heat but not harm the skin.

Putting It All Together

With weekly treatments for a month, photodynamic therapy could remove 2/3 of blemishes and half of blackheads and whiteheads.

The biggest positives of this method are that:

  • Acne bacteria can build a resistance to antibiotics but not light therapy.
  • This is safe for pregnant women.
  • Advantages exist for all skin types.
  • A dermatologist can safely perform the treatment with little risks.

The possible downsides for this treatment are that:

  • Acne is not permanently removed.
  • This therapy is only part of an effective skin care regime.
  • Injuries can occur when falling asleep or using DIY treatments.
