When Should I Start Using The Neck Serum ?

The skin on the neck is different than the body and face – it is thinner, more delicate and holds less sebaceous glands which means it might show faster signs of age. The Neck Serum is formulated specifically for the neck. The Neck Serum contains 7.5% Peptide to help trigger skin’s own collagen production. The Neck Serum helps firm and lift. The Neck Serum doubles as a moisturizer.

Answer

Why is pH Level Mentioned On The Package?

During the formulation process we optimize the pH of the formula. We believe it directly impacts the safety and efficacy of the formula. The pH objective will vary based on product purpose. On the secondary packaging (carton) we provide a pH range. The reason pH range is indicated is that pH may vary during the manufacturing process and/or slightly change over time. Formulas that do not contain enough water will not have a pH listed.

Answer

Is This Product Certified Eczema-Safe?

No. This product does not hold The Seal of Approval by the National Eczema Association.

Answer

We formulate without ingredients on the EU's prohibited substances list (Regulation No.1223/2009, Annex II). This formula is Dermatologist-Tested and Hypoallergenic. If you have any specific concerns, we recommend consulting your doctor prior to use.

Answer

Is This Product Certified Gluten-Free, Soy-Free And Nut-Free?

This product is not certified gluten-free, soy-free or nut-free. This product is manufactured in a facility where gluten, soy and nuts may be used. If you have an allergy to gluten, soy or nuts, we recommend that you do not use this product. If you still wish to try, please consider a patch test.

    Can’t ask for more than perfection

    As a product formulater myself, this product has it all. Great and effective emollients and a handful of some of the best skincare peptides out there … and in meaningful concentrations. Product is a bit heavy, but to be expected with the ingredients in it. However, it goes on smooth and soaks in very well with no residual afterfeel. And it’s great for the whole face … not just neck area.
