Lovi Assistant explains
- Highly suitable for your combination skin, this moisturizer effectively balances oil production with niacinamide and provides essential hydration with squalane, benefiting both oily and dry areas.
- The inclusion of glycerin and panthenol further enhances barrier resilience and offers excellent moisturizing properties, supporting overall skin health.
- The formulation is safe for your acne-prone skin, as it contains no harsh or irritating ingredients.
How to apply
- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help keep breakouts under control.
- Apply after your cleanser and toner, and make sure to use your SPF right after in the morning.
- Gently spread a small amount of moisturizer over your face using soft motions. Let it absorb into the skin for a minute before getting dressed or applying makeup.
- Apply on slightly damp skin to help lock in extra moisture. This keeps your combination skin balanced without feeling heavy.
- Avoid the eye area and do a patch test before your first use. Stop using if you feel any irritation.
