Applying a hydrating concealer stick correctly involves a few steps that ensure you get the most out of the product and achieve a natural, flawless finish. Here's how to do it:

1. **Preparation**: Start with a clean, moisturized face. The hydration from your moisturizer will help the concealer blend more easily into your skin. If you use a primer, apply it before the concealer.

2. **Color Selection**: Choose a concealer that matches your skin tone. If you want to cover dark circles or spots, you might want to go one shade lighter.

3. **Application**: Swipe the concealer stick directly onto the areas you want to cover. This could be under your eyes, around your nose, on blemishes, or any areas with discoloration. Remember, less is more. You can always add more if needed.

4. **Blending**: Use your ring finger or a beauty blender to gently blend the concealer into your skin. The warmth of your finger can help melt the product into your skin for a more natural look. Blend outwards for a seamless finish.

5. **Setting**: If you have oily skin or want your concealer to last longer, you can set it with a translucent powder. Use a fluffy brush to lightly dust the powder over the areas where you applied the concealer.

6. **Rest of Your Makeup**: Proceed with the rest of your makeup routine.

Remember, the key to a natural look is to blend well and use the right amount of product. A hydrating concealer stick is a great tool for achieving a fresh, dewy look.
