NAD+, EGF, Collagen and Peptides: A Stack for Firmer-Looking Skin

Why CloudSense NAD Serum combines NAD+, EGF, low-molecular collagen and 8 peptides, what each one does for the look of firm skin, and where the evidence stands.

Most serums bet everything on one hero ingredient. But the look of firm, bouncy skin depends on several things at once: how hydrated it is, how smooth the surface looks and how well skin keeps up with its own daily maintenance. That is the case for a stack.

Why combine NAD+, EGF, collagen and peptides?

Each ingredient speaks to a different part of how skin looks and feels. Collagen is about moisture you can feel now. EGF and peptides are signaling molecules associated with the look of firmness over time. NAD+ is tied to the energy cells run on.

None of them is magic on its own. Together, they cover more ground in a single lightweight step, which is exactly what a busy morning needs.

One serum, four ingredient families: NAD+, EGF, collagen and 8 peptides.

What does each ingredient do?

NAD+: the cellular energy coenzyme

NAD+ is a coenzyme cells use to turn nutrients into energy and to power enzymes involved in cell maintenance. Animal studies show NAD+ falling with age in several tissues, skin included, and one human study found lower levels in older skin, though reviewers call the human data limited.

Research on NAD+ applied to skin is early and mostly done in the lab. In this formula, NAD+ is the future-facing ingredient, included alongside ingredients whose look and feel you notice today.

What is EGF in skincare?

EGF stands for epidermal growth factor, a small signaling protein your body makes naturally. In skin, it is part of the messaging system associated with renewal.

A 2021 systematic review in the Journal of Cutaneous and Aesthetic Surgery gathered 49 studies on EGF for aesthetic use. Many reported improvements in the look of wrinkles, texture and hydration. The authors were also clear that many of those studies were not rigorously controlled, and that EGF did the most when delivered into the skin rather than on top of it.

A 2023 systematic review in the Journal of Cosmetic Dermatology looked at topical growth-factor products and found modest improvements in texture and fine lines, with a low rate of side effects, while noting that the formulas studied varied widely.

Translation: EGF is a sensible supporting ingredient for the look of smoother, firmer skin. It is not a miracle, and anyone promising one is not reading the research.

Low-molecular collagen: why it feels plumping

Collagen is the protein that gives skin its structure. Collagen in a serum does not replace your own. It works as a hydrating ingredient on the surface of the skin.

Low-molecular collagen is broken into smaller pieces, which suits a thin, fast-absorbing serum. That is where the plump, cushioned feel comes from. As the American Academy of Dermatology puts it, moisturizer traps water in the skin, giving it a more youthful appearance.

What do the 8 peptides do?

Peptides are short chains of amino acids. A 2020 review in Frontiers in Chemistry groups cosmetic peptides into three main families: signal peptides, carrier peptides and neurotransmitter-inhibiting peptides.

Signal peptides are associated with the look of firmness. Others are chosen for the look of smoother expression lines. Using a blend of eight gives the formula range instead of relying on a single one.

The honest limit: peptides love water and do not cross the skin barrier easily, a challenge that same review flags. Good formulation and daily consistency matter more than any single peptide name on the label.

The stack at a glance

Ingredient What it is Role in the formula The evidence, honestly
NAD+ A coenzyme cells use for energy Supports the look of healthy, radiant skin Early and mostly lab-based
EGF A natural signaling protein The look of renewal and firmness Promising, with mixed study quality
Low-molecular collagen Structural protein in small pieces Hydration and a plump feel Well understood as a hydrator
8 peptides Short amino-acid chains The look of firmness and smoother lines Growing; skin penetration is the challenge

What this stack will not do

  • It will not change skin the way an in-office procedure can.
  • It will not replace daily sunscreen, which the American Academy of Dermatology names as the first step for skin that ages well.
  • It is not an overnight change. Cosmetic results build gradually with consistent use.

What it will do is give you one fast-absorbing step that hydrates, feels good on skin and supports the look of firmer, smoother, more evenly toned skin, morning and night.

Why texture decides whether you keep using it

CloudSense NAD Serum is a lightweight red serum in a 30 ml glass dropper bottle. It absorbs fast, it is non-sticky and it sits well under moisturizer and makeup. It is non-comedogenic tested, with no artificial colors or fragrance.

A serum you enjoy using is a serum you actually use twice a day. With any firming routine, consistency beats intensity every time.

How to use it: after cleansing and toner, press 2 to 4 drops into your face and neck, morning and night. Follow with moisturizer, and in the morning finish with SPF.

Ingredient stack FAQ

Can I use EGF and peptides together?

Yes. They are already combined in this formula. If you add other active products, introduce them one at a time so you know how your skin responds.

Does collagen in a serum boost my own collagen?

Not directly. Collagen applied to skin works mainly as a hydrator, which is why skin looks and feels plumper after you use it.

Why use NAD+ if the research is early?

Because it is paired with ingredients that deliver the look and feel you want today, while NAD+ adds a forward-looking ingredient to the formula. We would rather tell you the evidence is early than overstate it.

Is it suitable for oily skin?

It is a lightweight, non-sticky serum that is non-comedogenic tested, so it layers comfortably on most skin types. Patch test first as always.
