- Purpose: It is used to target hyperpigmentation, uneven skin tone, blemishes, acne scars, and stubborn dark marks (such as on the knuckles, elbows, or knees). [1, 2, 3]
- Key Ingredients: Its formula typically relies heavily on fruit acids (AHAs) and exfoliating agents to rapidly shed top skin layers and lighten discoloration. [1, 2, 3]
Common Usage Practices
Because this formulation is known to be highly potent and can be quite harsh on sensitive skin, skincare users generally share specific instructions: [1]
- Dilution: Many users strongly recommend diluting the solution by mixing it in a 50/50 ratio with a gentle base, such as rose water or a hydrating essence, to prevent chemical irritation or skin barrier damage. [1]
- Frequency: It is typically suggested to limit use to 2 to 3 times a week rather than every day. [1]
- Application Time: It is strictly recommended for nighttime use. AHA fruit acids make the skin highly sensitive to sunlight, which can trigger severe sunburn or reverse the lightening effects if exposed to UV rays. [1]
- Sun Protection: Applying a broad-spectrum sunscreen during the day is absolutely required while using this product to protect the skin barrier.
