Chlorophyllin copper complex is a semi synthetic, water soluble derivative of chlorophyll in which magnesium is replaced with copper. Its porphyrin copper structure allows it to scavenge free radicals directly, and separate clinical assessment work has found it stimulates markers of collagen and elastin activity in the extracellular matrix, consistent with a photoaging repair mechanism.
A clinical study evaluating topical copper chlorophyllin in women with photodamaged skin found genuine visible improvement, and a smaller pilot study looked at its effect on facial acne and enlarged pores. These are legitimate peer reviewed studies, but they are generally small, pilot scale trials, and copper chlorophyllin carries known photosensitizing chemistry at higher concentrations used in other medical contexts.

Our team reviews ingredient research and uses up-to-date evidence to rate ingredients based on the categories below.
Best
Ingredients with the most rigorous and convincing evidence. These are the standouts backed by consistent findings across independent, peer reviewed clinical research.. When we call an ingredient Best, it has earned that distinction through genuine, reproducible proof that it improves skin.
Good
Reliable, well tolerated ingredients that do their job without complaint. They may not carry the headline benefits of a Best rated active, but they hydrate, stabilize a formula, or support the ingredients around them in ways that make a real difference in how a product performs and feels.
Average
Ingredients that are perfectly safe and serve a clear function, typically as an emollient, thickener, or filler, but do not offer any meaningful skin benefit beyond that basic job. Not a red flag, just not a reason to choose one product over another.
Bad/Worst
Ingredients with documented potential to irritate skin, disrupt the barrier, or trigger sensitization in some users, often synthetic fragrance, drying forms of alcohol, or certain essential oils. Not automatically a dealbreaker for every skin type, but worth knowing about before you commit to a product.
