Avoid applying matrixyl together&nbsp; with lactic acid, salicylic acid, Vitamn C or glycolic acid.&nbsp; They don't work together. If you need to use these products, apply them on alternate days, not at the same time.&nbsp;</FONT></P><P>&nbsp;</P><P><FONT size="3">Niacinamide works well with matrixyl.&nbsp;</FONT></P><P>&nbsp;</P><P><FONT size="3">Retinol can be used, but best to apply it on a different day or wait at least 30 minutes after the matrixyl.&nbsp;</FONT></P><P>&nbsp;</P><P><FONT size="3">The conclusion: don't apply these serums at the same time if you want to avoid irritation.
