Use alone or under a lip tint, versatile to be applied either day or night. I have not tried it under lipstick yet, but it should be alright to use as it’s lightweight, non-sticky and won’t change colour.
It is a lip conditioner mainly used to smoothen and soften the lips, mixed with virgin coconut oil and rose absolute. For me I find it to be mildly hydrating, which requires a more application to feel the moisturising effects. Generous amount is given 0.17 oz in a 5ml glass pot.
