Step-by-step guide:

1. Start with clean, moisturized skin: Apply your regular skincare and any other desired primer. 
2. Apply the orange corrector sparingly: Take a small amount of the Kay Beauty Orange color corrector and apply it directly to the areas of concern. 
3. Focus on problem areas: Use the orange corrector to neutralize dullness, dark circles, or pigmentation on dusky skin tones. 
4. Gently pat and blend: Use your fingertips or a brush to pat the corrector onto the skin. Blend the edges to avoid a harsh line, but don't blend it completely away. 
5. Layer your base makeup: Apply your regular foundation and concealer over the color-corrected areas to conceal the orange tone and create a flawless, even base.
