The Innisfree Retinol CICA Repair Ampoule is often praised for its ability to improve skin texture and brightness. Here are some tips to help brighten dull skin using this product:

• Apply at Night: Retinol products are best applied at night to avoid sun sensitivity. This ampoule is no exception, so make sure to use it before bed.
• Start Slowly: If you're new to retinol, start with a small amount and gradually increase usage to allow your skin to adjust. This can help minimize potential irritation.
• Layer with Hydrators: After applying the ampoule, layer with a hydrating serum or moisturizer to lock in moisture and enhance the brightening effect.
• Be Consistent: Retinol works best with consistent use. Stick to a regular routine to see the best results.
• Sun Protection: During the day, use a good sunscreen to protect your skin from UV damage, which can dull your complexion.
