Matcha in Skincare: What Are the Benefits and Risks?

Efficacy of Matcha in Skincare

Antioxidant Effects: Matcha is rich in catechins (e.g., EGCG), which effectively neutralize free radicals, reduce oxidative stress, and delay skin aging and wrinkle formation.
Anti-Inflammatory Effects: Soothes the skin, reduces redness, sensitivity, and inflammation. Suitable for acne-prone skin or those with rosacea.
Brightens Skin Tone: Helps inhibit melanin production, evens out skin tone, and improves dullness and dark spots.
Oil Control & Acne Prevention: Regulates sebum production, minimizes pores, and prevents breakouts and acne.
Hydration & Repair: Contains polyphenols and vitamins that strengthen the skin barrier, boost moisture retention, and repair damage.

Allergic Reactions: Individuals sensitive to tea polyphenols or caffeine may experience rashes, itching, or contact dermatitis.
Skin Irritation: High concentrations of matcha extract may cause irritation, burning, or peeling, especially on sensitive or compromised skin.
Photosensitivity: Certain components (e.g., catechins) may increase photosensitivity risk under sunlight; recommended to use with sunscreen.
Quality Concerns: Low-quality matcha may contain pesticide residues or heavy metals. Opt for organic-certified products to mitigate risks.
Ingredient Interactions: May exacerbate irritation when combined with potent acids (e.g., AHAs) or retinol; use cautiously in formulations.
