Lovi Assistant explains
- Offers moderate brightening for your oily skin due to alpha arbutin and kojic acid, which help even skin tone, while glycolic acid and salicylic acid provide mild exfoliation and seboregulation. Witch hazel water further supports oil control, though stronger concentrations of salicylic acid would be more beneficial for managing oily shine.
- The inclusion of Aloe Barbadensis Leaf Juice and Centella Asiatica Extract ensures a soothing experience, minimizing potential irritation for your oily skin.
- The product is safe for your skin, with no harsh ingredients and a focus on soothing components.
How to apply
- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.
