Hi,
Generally, after facial laser treatment, the skin may be a little sensitive and prone to developing pigmentation.
Hence, after facial laser treatment, avoid harsh soaps and facial creams that may worsen the sensitivity. Such creams include alpha hydroxy acids and tretinoin. These creams may be used judiciously several weeks later after the skin normalizes. A gentle moisturizer used regularly will help the lasered skin recover faster.
It is important to avoid UV exposure after facial laser treatment to minimize post-laser hyperpigmentation. A broad spectrum sunscreen and other sun protection methods are a must during the immediate post-laser period.
Smoking should be avoided as it delays wound healing and will undo the anti-aging benefits of the laser treatment.
A common concern raised by my patients is what food to avoid. Actually, there is no food that may cause any issues post-laser, so it is permissible to consume all food in moderation.
Hope this helps!
