What is the difference between the red light versus the blue light when used in aesthetics?
Blue light:
- Shorter wavelength, does not penetrate as deep into the skin, GREAT for acne
- Able to target pores in order to push out debris and cleanse the skin
- Kills bacteria, decreases oil gland size, decreases inflammation
- Stimulates pigment production, so if you have dark spots, you DO NOT want blue light
Red light:
- Longer wavelength, improves collagen and fibroblasts
- Decreases oil production, but is ONLY effective for inflammation form of acne
- Studies have shown there was an 80% decrease for inflamed acne lesions over a 12 week period
- Because of a longer wavelength, red light should not be used on someone with rosacea or eczema
Can hydrafacial on my scalp help with hair growth?
Yes! Red light helps with repair and can stimulate the hair follicle. Red light therapy works even better after exfoliation. With all of the oil production and dandruff on the scalp, getting a hydrafacial on the scalp will help the red light penetrate better and in return aid in hair growth. Red light improves fibroblasts, which will induce collagen production.
