In summary

  • The 8T3 Essentials Lash & Brow Serum uses soluble CD83 as its only active ingredient, deliberately excluding prostaglandins and prostaglandin analogues. 
  • Prostaglandin-based ingredients can cause permanent dark circles and iris discoloration, risks that do not exist with the 8T3 Essentials Lash & Brow Serum. 
  • The eye area is more sensitive than most other parts of the body: fewer ingredients means less risk of irritation.
  • Anyone buying a lash serum should check the ingredient list: the shorter it is, the better.
FAQ

Delimitation & Scientific Approach

Why does the 8T3 Essentials Lash & Brow Serum take a non-hormonal approach?
Soluble CD83 is hormone-free and acts directly on the follicle without interfering with hormone levels. Prostaglandins and their analogues, which are common in other lash serums, can cause lasting side effects, which is why Mallia has chosen not to include them.
What sets the 8T3 Essentials Lash & Brow Serum apart from other lash serums?
The 8T3 Essentials Lash & Brow Serum contains only soluble CD83 as its active ingredient. That eliminates the side effects associated with prostaglandin analogues: dark circles that do not reverse and permanent iris discoloration.
Why are fewer ingredients often better when it comes to lash serums?
The eye area is one of the most sensitive parts of the body, and every additional ingredient is a potential source of irritation. A short ingredient list is not a sign of a weak formula; it is usually a sign of a careful one.

Description

The active ingredient in the 8T3 Essentials Lash & Brow Serum is soluble CD83. That was a deliberate choice. Prostaglandins and prostaglandin analogues are common in the lash serum market but are currently under review by several regulatory authorities, because they can cause serious side effects: dark circles that do not reverse and iris discoloration that is permanent. 

The eye area does not handle a long ingredient list well. Most people have noticed this themselves at some point. Fewer ingredients means fewer triggers for irritation, which is why checking the ingredient list of any lash serum is worth doing: the shorter, the better. 

The 8T3 Essentials Lash & Brow Serum contains no prostaglandins and no hormones.
