How long does it take to judge the effectiveness of a product?
The skin completely renews itself in about 30 days. And this number increases when we act with age. So, how long does it take to judge the effectiveness of a product?
How long does it take to judge the effectiveness of a product?
It therefore takes at least 1 month to judge the effectiveness of a product.
Indeed, it takes an average of 28 days for the epidermis to renew itself:
From 21 to 28 days for young skin.
Longer, up to 35 or 40 days, for mature skin.
It is therefore recommended to wait at least 28 days to really assess an epidermal effect.
For actions on the dermis, the action time may be longer:
A deeper penetration of the active ingredients and an action on the fibroblasts (cells that make up the dermis) are necessary to reactivate the collagen and energize the internal cells.
6 to 8 weeks may thus be necessary to notice an effect in terms of firmness and elasticity…
We often expect a lot from our cosmetics! and we can't wait to see the first results of our new cream on our skin. This is why it is not exceptional that we quickly abandon a product if we do not see positive effects on our skin after a few days…
But if we are in a rush to find them ineffective, our creams need to be used for a while before we can determine whether or not they work well on our skin.
We often think that faithfully following the same beauty routine (or applying a new skincare product) for a month is more than enough to get an idea.
