Applying lactic acid correctly is key to leveraging its benefits as an exfoliant in your skincare routine. The process involves specific steps and timing within your regimen to ensure effectiveness and proper skin care.
To apply lactic acid, integrate it into your routine once or twice daily, specifically after cleansing and toning. After its application, you should follow with your other leave-on skincare products, concluding with sunscreen during the day and a moisturizer (if needed) at night.
Step-by-Step Lactic Acid Application Guide
The application of lactic acid fits seamlessly into a well-structured skincare routine. Follow these steps to ensure proper integration and efficacy:
- Cleanse Your Skin: Begin by thoroughly cleansing your face to remove any makeup, dirt, or impurities. This prepares your skin for better absorption of subsequent products.
- Apply Toner: After cleansing, apply your preferred toner. Toning helps balance the skin's pH and prepares it for active ingredients.
- Apply Lactic Acid Exfoliant: Once your skin is cleansed and toned, dispense a small amount of your lactic acid exfoliant onto your fingertips. Gently apply it evenly across your face, avoiding the eye area. Allow it to absorb fully into the skin.
- Follow with Other Leave-on Products: After the lactic acid has absorbed, you can proceed with other leave-on products in your routine, such as serums (e.g., hydrating, antioxidant, or brightening serums) or targeted treatments.
- Finish Your Routine:
- During the Day: Always finish your daytime routine with a sunscreen to protect your skin from UV damage, which is especially crucial when using exfoliants like lactic acid.
- At Night: Conclude your nighttime routine with a moisturizer, if your skin needs it, to provide hydration and support the skin barrier overnight.
Recommended Frequency
Lactic acid can be incorporated into your skincare regimen once or twice daily. The optimal frequency depends on your skin's tolerance and the concentration of the lactic acid product you are using. It is often advisable to start with a lower frequency and gradually increase as your skin adapts.
Important Finishing Touches
The final steps in your routine after applying lactic acid are crucial for skin health and protection:
- Sunscreen (Daytime): Lactic acid, as an exfoliant, can increase your skin's sensitivity to the sun. Therefore, daily application of a broad-spectrum sunscreen with adequate SPF is non-negotiable to prevent sun damage and hyperpigmentation.
- Moisturizer (Nighttime): While not always explicitly "needed" for everyone, applying a moisturizer at night helps to lock in hydration, support the skin's natural barrier, and soothe the skin after exfoliation. Listen to your skin's needs to determine if this step is necessary for you.
