Vitamine E 10% | $11.95

All actives contain 6ml of hyper-connected active (x10 times a standard concentrated serum), and have a minimum duration of 70 uses.

Of course, the bases and actives can be removed, stored and used again for 12 months.

Although this can happen in traditional cosmetics, with Lesielle you do not have this problem. This is because the active ingredients are mixed right at the moment of application and therefore do not have time to interact with each other. This is one of the major advantages of the isolated formulation. The only thing we do not recommend is to use the same ingredient twice or to combine two exfoliating actives (range imperfections) to avoid an action that is too powerful for the skin. In addition, you will have to take into account, but this is something to be learned by each person, which ingredients your skin tolerates.

Although all our actives have passed dermatological control individually, due to their high concentration, our recommendation is that you always mix the actives with a base cream in at least a 1:2 mixture.

We must begin by clarifying that there are no active ingredients that are compatible or not with sensitive skin, since it can react to any active ingredient, no matter how mild it may be. What we can say is that there are active ingredients that are more or less likely to be compatible.

You can find the degree of compatibility with sensitive skin in the data sheet of each active ingredient. In addition, you can filter in the category of active ingredients by their expected "compatibility" and, if you are in a physical store, you will find it indicated on their packaging or corresponding box.

The main properties are those in which the active ingredient is most effective. Secondary properties are properties that, as their name indicates, are also present, but are not the most outstanding properties of the active ingredient.

We recommend always testing each active and each base separately (especially on very reactive skin) to ensure that each of the elements are compatible with the skin on which they are to be used.

Lesielle recommends the following testing process:

First, test a base with each active separately. Apply to a sensitive area of the skin (behind the earlobe or on the inside of the forearm) and wait 48h to confirm good compatibility.

Then, once the actives have been found to be compatible individually, we should test their incremental mixing, increasing the number of combined actives as follows waiting after each test 48h.

SCHEME:

Being a base B and the actives we want to test A1, A2 and A3:

B + A1 / B + A2 / B + A3.
