Lovi Assistant explains
- Offers moderate exfoliation for your normal skin, as betaine salicylate and willow bark water work to decongest pores and promote skin renewal for pigmentation concerns.
- Panthenol and sodium hyaluronate further support your skin's barrier and provide hydration, enhancing the overall comfort and efficacy of the formula.
- The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use your exfoliant PM once a week to start, moving up to twice a week if your skin likes it. Always apply SPF during the day while using this product.
- Apply this exfoliant step right after your cleanser and toner, and before your moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it dry. Avoid rubbing your face hard.
- Apply the product on clean, completely dry skin to make sure it works best for your pigmentation goals.
- Remember to avoid the delicate eye area and do a quick patch test before using it for the first time.
