EGCG

Ingredient · In our Dark Spot Treatment

EGCG (epigallocatechin gallate), from green tea

EGCG is one of the antioxidant compounds in green tea. In skin care it's used to calm and protect, and green tea extract has been tested in a handful of small acne trials.1

Early evidence

EGCG isn't an FDA-approved drug for any skin condition. The human studies use green tea extract, which contains EGCG along with other compounds, and they're small.1 Our creams are compounded by a licensed pharmacy, and compounded versions are not FDA-approved.2

FDA-approved for this useWell studied, used off-labelEarly evidenceLittle or no human data

The studies below used FDA-approved products or other forms. Our compounded version hasn't been studied in trials, and results may differ.

What it is

EGCG belongs to a family of plant antioxidants called catechins. Antioxidants help neutralize unstable molecules called free radicals.

Why it's in this product

In our Dark Spot Treatment, EGCG plays a supporting role next to the stronger brighteners. Think of it as a calming, protective extra rather than the main event.

What the studies in people show

  • Meta-analysisFewer inflamed breakouts with green tea extractA pooled analysis of five small randomized trials (about 250 people) found green tea extract reduced inflamed acne spots. Applied to the skin, it also reduced blackheads and whiteheads, without significant side effects.1

What we don't know yet

No good trials have tested EGCG for dark spots in midlife skin, and the acne studies used green tea extract, not purified EGCG. We include it as a gentle supporting ingredient, not a proven brightener.

Safety, in plain English

Green tea extract was well tolerated in the trials above.1 As with any cream, stop and tell your clinician if you get a rash or irritation.

A licensed clinician reviews your health history and decides whether this cream is appropriate for you. Exploring it here never means you'll get a prescription.
