Lovi Assistant explains
- Offers moderate suitability for normal skin, as sulfur and niacinamide provide mild keratolytic action and seboregulation, which are supportive for your pigmentation concerns by offering general cleansing benefits.
- The formulation includes allantoin and dipotassium glycyrrhizate, which are soothing ingredients that contribute to a good safety profile for your normal skin.
- The product is safe for your normal skin due to the absence of prohibited or harsh ingredients and the presence of soothing components.
How to apply
- Use this cleansing mask once a week to start, and increase frequency only if your skin feels fine.
- Apply the cleansing mask in your weekly routine after the cleanser and enzyme powder, but before the hydrating toner.
- Spread an even layer over your face while carefully avoiding the delicate eye area.
- Apply the cleansing mask to clean and dry skin for the best and most comfortable results.
- Always do a patch test before your first use and avoid combining it with strong acids.
