Is there any benefit to combining EGCG with other skincare ingredients, and are there any that should be avoided?
Combining EGCG with other antioxidants, such as vitamin C, can enhance its skin-protective benefits due to the synergistic effect of multiple antioxidants fighting free radicals. However, care should be taken when combining it with strong acids or retinoids, as this can potentially lead to irritation or compromise the stability of EGCG in the formulation.
