Determining Your Seasonal Undertone

Skin undertone is the subtle hue beneath the surface that remains constant, yet the appearance of skin color shifts due to environmental exposure and seasonal light. Many assume that a change in depth implies a change in undertone, leading to the common error of purchasing foundation that sits incorrectly on the skin. Understanding the distinction between depth and saturation is essential for consistent makeup application throughout the year.

This guide establishes a objective process for checking your undertones without relying on subjective sunlight exposure. By using controlled environments and neutral references, you can determine if your skin maintains a consistent warm, cool, or neutral classification regardless of the season.

  1. Establish a neutral zone. Select a room with consistent, indirect natural light. Avoid using bathroom vanity lighting or colored light bulbs, as these introduce artificial warmth or coolness. Stand facing a window during the middle of the day to ensure full-spectrum light reaches your skin without creating harsh shadows.
  2. Clean the surface. Remove all cosmetics from your jawline and neck area. Residue from previous applications or skincare can influence your perception of skin hue. Ensure your hair is pulled back completely to prevent casting shadows on the face.
  3. Apply white textile comparison. Hold a piece of pure white fabric or clean white paper directly against your jawline. Observe the immediate reaction of your skin color against the stark white edge. Look for hints of peach, gold, pink, or blue that become more prominent when contrasted with the neutral white.
  4. Check vein coloration. Examine the veins on the inside of your wrist. While this is a secondary indicator, it serves as a reliable cross-reference for the analysis done in the previous step. Cool undertones typically present as blue or purple, while warm undertones appear green or olive.
  5. Document seasonal variation. Note whether your skin appears to pull more towards yellow-gold or pink-red during the peak of your summer season. True undertones do not change, but the saturation can become more pronounced as the skin darkens. Adjust your product selection based on depth, not by swapping your undertone category.
Depth changes with the season, but your undertone is a fixed baseline.
