Peptides & Ceramides: Stronger Barrier, Smoother Skin

by ThankMeNow Editors on Sep 12, 2025
Peptides and ceramides are the powerhouse duo for building stronger, smoother, and more resilient skin. Peptides, made of short amino acid chains, act as messengers that stimulate collagen and elastin to improve firmness, texture, and elasticity. Ceramides, which make up nearly half of your skin’s barrier lipids, seal in moisture and prevent irritation, dryness, and fine lines caused by environmental stress.

Ceramides (NP/AP/EOP) – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Ceramides are a family of waxy lipid molecules known as sphingolipids. They are composed of a sphingosine base bonded to a fatty acid. In the stratum corneum (the outermost layer of the skin), ceramides make up approximately 50% of the lipid matrix. The specific types—Ceramide NP, Ceramide AP, and Ceramide EOP—refer to their chemical configurations. For example, Ceramide NP consists of a Normal fatty acid and a Phytosphingosine base. These lipids are essential for maintaining the skin's lamellar structure, which acts as a semi-permeable barrier. Without them, the "brick and mortar" of the skin fails, leading to Transepidermal Water Loss (TEWL) and increased penetration of environmental irritants.

Ceramides – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Ceramides are waxy lipids naturally found in the skin’s outer layer (stratum corneum). Along with cholesterol and fatty acids, they create the barrier matrix — the waterproof shield that prevents water loss and blocks pollutants. As we age or over-cleanse, ceramide levels drop, leading to dryness, flaking, and sensitivity. Replenishing them restores comfort and balance.
