Do you want to know how the power of light can improve your skin? In this article, we dig deep into the science behind treating skin acne with red light therapy.  


Acne Causes 

There are several things that may cause acne. The most common causes include:

  • Excess oil production;
  • Hormonal changes;
  • Clogged hair follicles;
  • Bacteria;
  • Inflammation. 

When dead skin cells and excess sebum (oil) blend into each other and clog pores. This sends an alarm to your immune system, which starts to push out the substances that are stuck in hair follicles. As a result, inflammation occurs, and whiteheads are popping up on the surface of your skin. 

Common Acne Treatments

Depending on the severity of acne, it may require a combination of treatments. Here are the few that are tried and tested:

Double cleansing

A proper cleansing system is important when treating acne. This ensures that you wash off the excess sebum and dead skin cells before they clog pores. Choose products according to your skin type and if possible, get a dermatologist’s opinion on your daily routine. The best cleansing practice is to start with an oil-based cleanser and follow it up with a water-based one. First breaks down the products and sebum, and the second step effectively removes it. 

Chemical exfoliation

Simple cleansing is not enough for improving your skin condition and texture. Dermatologists recommend using chemical exfoliants on a weekly basis. If you’re suffering from clogged pores, salicylic acid exfoliant can be your savior as it reaches deep into the hair follicle and dissolves the buildup oil. 

Oral medications

Topical treatments aren’t always effective for treating acne. In such cases, doctors prescribe drugs that target acne causes. Very common meds are antibiotics and retinoids. The former fights the bacteria, while the latter targets every possible cause of acne. The retinoids are only prescribed when nothing else works because they come with their fair share of adverse effects. 

Maintaining a proper skincare regimen is a must, but before you sign up for strong medications, it’s worth considering red light therapy as an alternative.
