Application of the Clarins Lip Comfort Oil is straightforward. Simply unscrew the cap and use the applicator wand to glide the oil evenly over your lips. No specific setup is required. It is highly compatible with virtually all lip care routines; you can apply it as the first step to nourish, or as the last step to add shine and comfort over other lip products. For care, ensure the cap is tightly closed when not in use to prevent product degradation and maintain hygiene. Store at room temperature, away from direct sunlight or extreme heat. To ensure cleanliness, avoid touching the applicator directly with unwashed hands.
