Lip serums are an essential part of a comprehensive skincare routine. They are designed to deeply nourish, hydrate, and protect the lips, offering benefits that go beyond those of a regular lip balm.

The best time to use a lip serum in your skincare routine is after cleansing and exfoliating, but before moisturizing. This is because serums are formulated with smaller molecules that can penetrate deeply into the skin, delivering a high concentration of active ingredients.

Here is a step-by-step guide on when to use lip serum in your skincare routine:

1. **Cleanse:** Start by cleansing your face and lips with a gentle cleanser. This will remove any makeup, dirt, and oil, preparing your skin for the next steps in your routine.

2. **Exfoliate:** Exfoliate your lips gently with a lip scrub or a soft toothbrush. This will remove any dead skin cells and allow the serum to penetrate more effectively.

3. **Apply Lip Serum:** Apply a small amount of lip serum, massaging it gently into your lips. The serum will penetrate deep into the skin, delivering nourishing and hydrating ingredients.

4. **Moisturize:** After applying the serum, wait a few minutes for it to absorb before applying a lip balm or moisturizer. This will seal in the serum and provide an extra layer of hydration.

5. **Protect:** During the day, finish your routine with a lip product that contains SPF to protect your lips from sun damage.

Remember, consistency is key when it comes to skincare. Regular use of lip serum will result in healthier, softer, and more youthful-looking lips.
