Changes in skin colour (darker OR lighter than normal) can occur following laser resurfacing. Once the treated areas of skin have healed, the use of skincare products containing glycolic acid (an AHA ie alpha hydroxy acid) can aid in improving hyperpigmentation (Elucent Anti-Ageing products); however it is best to check first with the treatment provider. It is also important to protect treated skin from sun damage by using a broad spectrum SPF 50+ sunscreen. NB SunSense Anti-Ageing Face and Anti-Ageing Face Matte are highly protective SPF 50+ sunscreens which also contain a similar AHA, lactic acid.
