Glycerine

Strong humectant evidence. A clinical study using glycerin 5% with hyaluronic acid showed improved hydration and barrier function for up to 24 hours after one use. This formula has 10% glycerine, so hydration support is credible. (PMC)

• The 24-hour skin hydration and barrier function effects of a hyaluronic 1%, glycerin 5%, and Centella asiatica stem cells extract moisturizing fluidPeer-reviewed clinical study (PMC)

  Randomised, assessor-blinded study of a combined formula (hyaluronic acid 1%, glycerin 5%, Centella extract); shows combined-formula results, not glycerin or Pulp alone.

• Effects of Locally Applied Glycerol and Xylitol on the Hydration, Barrier Function and Morphological Parameters of the SkinPeer-reviewed clinical study (Acta Dermato-Venereologica)

  Volunteer study of glycerol and xylitol applied to skin; ingredient-level evidence, not a test of Pulp products.

Apricot Kernel Oil

Rich in oleic/linoleic acids; supports skin softness and barrier function;

  Study of apricot kernel oil extraction and its composition, including oleic/linoleic fatty-acid profile and antioxidant activity; oil-level evidence, not a test of Berry Thirsty.

Caprylic/Capric Triglyceride

Well-established emollient that reduces water loss and improves skin feel

• Effect of an Emollient Emulsion Containing 15.0% of Caprylic/Capric Triglyceride on the Urocanic Acid of the Stratum CorneumPeer-reviewed study (Life, MDPI)

  Small volunteer and ex vivo study of a 15% caprylic/capric triglyceride emulsion on hydration and water loss; ingredient-level evidence, not a test of the serum.
