Hello. Thank you for your inquiry. The flaking of StriVectin Tighten & Lift Peptight™ 360° Tightening Eye Serum can happen for several reasons: Application Layering: If the serum is applied too thickly, it may not absorb properly and could dry out, causing it to flake off. It's important to apply a thin, even layer to allow proper absorption. Mixing with Other Products: If the serum is layered over or combined with other products, especially those with silicones or heavy moisturizers, the texture can become incompatible, leading to pilling or flaking. Skin Type: For some people, especially those with dry or flaky skin, certain ingredients may cause dryness or flaking, especially if the skin isn't properly moisturized beforehand. Environmental Factors: If used in a very dry environment or alongside harsh weather conditions, the serum may not stay on the skin as expected, causing it to flake off as it dries. To prevent this, try using a smaller amount of the serum, applying it evenly, and allowing it to fully absorb before applying other products. Also, consider using a moisturizer to ensure your skin is well-hydrated.
