It’s natural to have complex feelings about noticing signs of aging.

10 Best Cosmeceutical Ingredients of 2024

By Dr Frank Yap, MD -
Image
A cosmeceutical is essentially a skincare product that contains a biologically active compound that is thought to have pharmaceutical effects on the skin. Both pharmaceutical and cosmeceutical grade skin care products actively effect skin at a cellular level, whereas cosmetic products have a shorter-term effect. They are usually used by doctors to restore pH, remove pigmentation, or restore the skin barrier. Cosmeceuticals must scientifically verify the claims stated on their packaging; as it is accepted that these formulations are backed by science, clinical studies, and rigorous testing. The main areas of concerns that these formulations address are ageing skin, sensitive/sensitized skin, sun damaged skin, acne/oily skin, loss of tone and elasticity, as well as superficial lines & wrinkles to encourage rapid cellular turnover that will renew and re-texturize the skin. Peptides composed of chains of amino acids give proteins their structure, and transport nutrients and signal mess...

The Fenbendazole Cancer Protocol has been gaining rapid interest over the past years following some fenbendazole advanced cancer success stories.

As with so many skin-care trends that have come before, this one is rooted in medicine — in this case, regenerative medicine, which is centered on developing and applying therapies to help the body heal itself. For example, stem cells — those biological blank slates that can turn into new skin, cartilage, or bone — are currently used in oncology to help the body produce new blood cells after high doses of chemotherapy.
