Vaseline can help reduce the appearance of wrinkles by sealing in moisture and preventing water loss from the skin. It creates a protective barrier that keeps skin hydrated, making wrinkles look less noticeable. However, Vaseline does not contain active antiaging ingredients that actually reduce wrinkles. It works best when applied over other skincare products to lock in their benefits. Use it at night on very dry areas or over your regular moisturizer. For treating wrinkles, combine Vaseline with products containing retinol, vitamin C, or peptides for better results.
