Sensitivity, Safety & the Eye Area
In summary
- It is not the eyelash itself but the follicle in the eye area that responds to active ingredients, and that is precisely where soluble CD83 works.
- Prostaglandin derivatives can cause redness, dark circles, and permanent iris discoloration and are currently under review by multiple regulatory authorities.
- The 8T3 Essentials Lash & Brow Serum contains no prostaglandins or prostaglandin analogues and is completely hormone-free.
- The eye area is inherently sensitive: if irritation occurs, stop applying the product and give the skin time to settle.

Description
The eye area is one of the most sensitive parts of the body. Active ingredients do not act on the eyelashes themselves but on the follicle from which each lash grows. Soluble CD83 in the 8T3 Essentials Lash & Brow Serum works at exactly that level, influencing hair growth within the follicle.
Prostaglandin derivatives have been used for years to promote eyelash growth, but are now under review by multiple regulatory authorities. Reported side effects include redness, hyperpigmentation, dark circles that may not reverse, and iris discoloration, typically from blue to brown, which is permanent. The 8T3 Essentials Lash & Brow Serum contains none of these ingredients and is hormone-free.
If irritation does occur with any product, stopping application is the right step. Promises of unusually fast growth are a warning sign: no product can speed up the natural growth cycle of an eyelash.
