Start by deciding the finish, shade family, and the occasion you have in mind. MAC Retro Matte Lipstick offers a long-wear matte finish, while Relentlessly Red sits in the classic red family, so match those traits to your preference. Consider your skin tone: cooler undertones look great with blue-based reds, warm undertones with warmer reds, and blue-based reds can read cooler on cool complexions. If you’re unsure, compare swatches or test on lips to see how the shade reads on you.

Undertones determine how the red reads on your lips and in your overall look. Warm, orange-based reds tend to brighten warm skin tones, while blue-based reds can read cooler on cool undertones. Shade depth affects how bold the color appears under different lighting, so layer it or blot to see the intensity. To judge accurately, try swatching on your lips or the inside of your arm and note how it sits with your natural undertones.

Beginner makeup users should start with a lip liner and apply in light, even layers for control. Pro users can build the color in thin layers, pressing lips together to set the pigment and then clean the edges with concealer for a crisp finish. Both approaches work best with a hydrating lip balm beforehand to prevent dryness. Finish with a blot if you want a more matte or lasting look.

Keep the lipstick capped and store it in a cool, dry place to maintain texture and longevity. Hydrate your lips with a balm before application to reduce dryness from the matte finish, then blot and reapply as needed. Pair Relentlessly Red with a compatible lip liner in red or nude to prevent feathering and help define the shape. When removing, use a gentle makeup remover to protect your lip skin and avoid over-wiping.

Relentlessly Red can flatter a wide range of skin tones, especially when chosen with the right layering and base. For daytime wear, apply a lighter layer or blot to soften the color, and pair with neutral eye makeup. For evening looks or events, build to full opacity and consider a matching lip liner to define the edges. If your undertones lean warm, a warmer red tone will harmonize better; if they lean cool, a blue-based red often works best.

MAC's Retro Matte Lipstick is the long-wear matte line from MAC, and Relentlessly Red is a shade within that line. This combination is popular for bold red looks that can be tailored with layers and lip liners. Consider undertone compatibility, layering technique, and how the shade fits your daily routine or special events. Avoid relying on price or model numbers when evaluating the shade; focus on how it will appear on you.
