How long do Microchannels last?
Microchannels typically stay open for about 24 hours,
depending on how fast your skin heals. During this time it is essential to be very gentle and avoid scrubs, acids, SPF, makeup, sweating, and introducing new products. Microchannels enter the healing phase for 2-3 days, where you may notice some texture on the skin. By day 4 they are healed and the skin looks and feels smooth.
