The product you mentioned, 'The Ordinary - Niacinamide 10% + Zinc 1%,' is a skincare solution formulated with a high concentration of niacinamide (Vitamin B3) and zinc. Here's a breakdown of its key features and usage instructions:

**Key Features:**

1. Niacinamide (Vitamin B3): Known for its skin benefits, niacinamide helps in reducing the appearance of skin blemishes and congestion.

2. Zinc Salt of Pyrrolidone Carboxylic Acid: Included to balance the visible aspects of sebum activity, helping to control excess oil on the skin.

3. Concentration: The formula contains a high 10% concentration of niacinamide, indicating a potent amount of the active ingredient.

**Usage Instructions:**

1. Purpose: This product is designed to address skin blemishes and congestion.

2. Application: Apply the formula directly to the face in the morning.

3. Compatibility: The product should be used with caution if you also use topical Vitamin C (L-Ascorbic Acid and/or Ethylated L-Ascorbic Acid) in your skincare routine.

4. Contradictions with Vitamin C: If you use a topical Vitamin C product, it is advised to apply it at alternate times with this niacinamide formula. Specifically, it suggests using Vitamin C in the evening (PM) and the niacinamide formula in the morning (AM). This is because Niacinamide can potentially affect the integrity of Vitamin C if applied simultaneously.

5. Contraindications: The only contraindication mentioned is related to the use of topical Vitamin C. Ensure that if you use Vitamin C, it should be applied at a different time to prevent any potential negative interactions.
