While lactic acid is often considered one of the gentler AHAs and this formula includes glycerin to help with moisture, sensitive skin requires extra caution. Before regular use, perform a patch test: apply a small amount to a discreet area like behind your ear or on the inner forearm. Wait 24-48 hours to check for any adverse reaction like redness, itching, or burning.
If the patch test is clear, introduce the product very slowly. Start with the lowest possible frequency (e.g., once every 10-14 days), use a minimal amount, and consider rinsing it off after just 1-2 minutes initially instead of leaving it on. Pay close attention to how your skin feels the next day. The goal is to support smoother, brighter-looking skin without triggering irritation.
It is crucial to avoid using the peel on visibly compromised, inflamed, or broken skin. Do not combine it with other potent exfoliants (like retinoids or other acids) on the same night, as this significantly increases the risk of irritation. Most importantly, because all AHAs increase photosensitivity, diligent use of a broad-spectrum SPF every morning is essential to protect sensitized skin from sun damage.
