01

What is Oligopeptide-1 (EGF)?

Plain language first. The technical label stays, but it never stands alone.

Overview

Epidermal growth factor sold under a cosmetic name. The healing research behind it is real and was done on broken skin, which is not the same as a serum on an intact face.

The technical version

Oligopeptide-1, the INCI designation for recombinant human epidermal growth factor, a 53-residue protein signalling through the EGF receptor to drive keratinocyte proliferation and migration. Clinical evidence is concentrated in wound healing rather than in cosmetic use on intact skin.

What it's used for

A topical growth factor used in skincare for repair, barrier support and post-procedure recovery.

02

How does Oligopeptide-1 (EGF) work?

What it does in the body, and where.

EGF is not a cosmetic invention. It is a signalling protein with a Nobel Prize behind it and a long wound-healing literature.

  1. 01
    It tells skin cells to divide
    EGF binds its own receptor on keratinocytes and triggers proliferation and migration, which is exactly what closing a wound requires.
  2. 02
    Size is the whole problem in a cosmetic
    At 53 amino acids this is a protein, not a peptide. Intact skin is built to keep molecules this large out, so a great deal depends on the delivery system and on whether the skin barrier is broken.
  3. 03
    The growth signal cuts both ways
    Telling cells to divide faster is useful in a healing wound. The same instruction is the reason caution is warranted with any active skin cancer or undiagnosed lesion, and why this is the one ingredient in the cosmetic category where that caveat is not boilerplate.

Where this compound is thought to act.

03

What else is it used for?

Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

  • Skin repair and barrier support, applied to the skinOTC / supplement
  • Recovery after cosmetic procedures such as lasers and microneedlingEarly research
  • Wound healing, which is where the underlying research comes fromClinical use
  • Added to lash and hair serums to extend the growing phasenone
04

How much, and do you cycle it?

The range, and whether you take breaks.

Serum, per product, daily. Not cycledCommunity practice

Used daily as part of a routine. The effect depends on continued use and returns to baseline when you stop, so there is nothing to cycle off.

How long does it stay in the body?

The half-life, and where the figure comes from.

Not measured, and not the right questionNo figure

This is a topical cosmetic ingredient. A blood half-life measures how fast something leaves the bloodstream, and these are not intended to reach it in meaningful amounts. What matters for a topical is how much penetrates the skin and how long it stays in the tissue, which is a different measurement and one that is rarely published.

You can compare this against the whole library to see where it sits.

05

What does it cost?

Typical dose and cost, in plain numbers.

Oligopeptide-1 (EGF) is not injected

It is taken on the skin (topical). Applied as a topical product at the concentration the manufacturer sets. There is no injected dose.

06

How do you store it?

Before mixing, and after.

Room temperature, out of light. Cap it tight after each use.

Oligopeptide-1 (EGF) ships as a cream, gel, or serum. Keep it at room temperature away from sun and heat unless the label says otherwise. Refrigerating an emulsion can split the texture. Watch for color, smell, or separation changes and stop using it if any appear.

07

What are the side effects and cautions?

Known cautions and warnings for this compound.
Handling note

Growth factors are large and fragile. Heat and light degrade them, which is why products carrying EGF are usually packaged airless or opaque and why a clear jar sitting on a windowsill is a reason to doubt what is left in it.

Who should avoid it

Check these before anything else.
  • A known allergy to this ingredient or to others in the same product
  • Broken, cracked, or actively irritated skin
  • Active skin cancer, or any lesion that has not been diagnosed, because this instructs cells to divide
  • A history of skin cancer, without asking a dermatologist first
  • Anyone who wants established safety data, because none exists for this compound in humans

Stop and get help

These are emergencies. Seek care.
  • A rash that spreads beyond where you applied it
  • Swelling of the face, lips, or eyelids, or any trouble breathing
  • Burning that does not settle after rinsing it off
  • Any mole or lesion that changes in size, shape or colour
  • Anything unusual, since there is no known safety profile to compare it against

Common effects

Expected, and usually mild.
  • Generally well tolerated on the skin.
  • It is a growth signal, so caution applies with any undiagnosed skin lesion.
  • Beyond the above, unknown. There is no reliable human data on what this compound commonly causes

Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.

08

Is Oligopeptide-1 (EGF) approved?

And where the numbers on this page come from.

Not as a medicine. Oligopeptide-1 (EGF) is sold without a prescription as a supplement or cosmetic ingredient, which is a different thing from being approved as a drug.

What has happened recently

Regulated as a cosmetic ingredient, not a drug. Cosmetic ingredients are not reviewed for effectiveness before sale in the US, so a product may legally claim an appearance benefit without a trial behind it.

What these words mean

Show glossary +
503A and 503B
The two kinds of compounding pharmacy in US law. A 503A pharmacy prepares medicine for one named patient. A 503B outsourcing facility makes larger batches under stricter manufacturing rules.
Agonist
Something that switches a receptor on. The opposite is an antagonist. It blocks the receptor instead.
Amino acid
The building blocks that link together in a chain to make a peptide or a protein. The order they sit in is what makes one peptide different from another.
Amylin
A hormone released alongside insulin that slows the stomach emptying and reduces appetite. Several weight loss compounds copy it.
Analog
A compound built to copy a natural one with small deliberate changes, usually so it lasts longer or holds onto its target more tightly.
Animal study
Research done in rats, mice or other animals. Most findings do not repeat in people, so an animal result is a reason to keep looking. It is not a reason to act.
Antibody
A large immune protein, far bigger than a peptide, engineered to lock onto one specific target. These are made by drug companies and are not sold as research powders.
Bacteriostatic water
Sterile water with a tiny amount of preservative, used to mix powdered peptides.
Banned in drug-tested sport
Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
Bioavailability
How much of a dose actually reaches your bloodstream. Most peptides survive stomach acid badly, so most of them are injected instead of swallowed.
Bioregulator
Very short peptides from a Russian research tradition, usually two to four amino acids long, sold for supporting a specific organ. Human evidence is thin and most of it is published in Russian.
Blend
One vial holding more than one compound, mixed together by the seller. Working out a dose means working out each ingredient separately, because they are rarely present in equal amounts.
Boxed warning
The most serious warning the FDA puts on a drug label, printed inside a black border. It flags a risk considered severe enough to sit above everything else on the label.
Bulks list
The FDA's list of ingredients that compounding pharmacies are allowed to use. A substance can sit under review on it for years without anything being decided either way.
Certificate of analysis (COA)
A lab report on a batch of product. It only means something if it names the batch you actually received, comes from an independent lab, and can be checked with that lab.
Clinical trial
A study that gives a treatment to people under a written plan and measures what happens. It is the only kind of evidence that can show something works in humans.
Compounding
A licensed pharmacy preparing a medicine to order. Being allowed to compound something is not the same as the FDA approving it, and the two get mixed up constantly.
Concentration
How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
Cycle
A stretch of time using a compound followed by a break. Most cycling patterns come from community practice. Very few have been tested.
DAC
Short for Drug Affinity Complex. An attachment added to a peptide so it grabs onto a blood protein and stays in the body for days instead of minutes.
Dead space
The small amount of liquid left sitting inside the needle and hub after you inject. On very small doses it can be a real share of what you meant to take.
Dilute
Adding more liquid to make a mix weaker. The amount of peptide in the vial does not change. It is just spread through more water, so each draw is bigger.
Endpoint
The result a trial said in advance that it would measure. A study can be reported as positive and still have missed the endpoint it set out to hit.
FDA approved
Reviewed by the FDA and cleared for a specific use, in a specific form, at a specific dose. Approval for one use is not approval for another, and approval in another country is not approval here.
Fragment
A short piece cut out of a larger natural protein. A fragment can behave very differently from the whole protein it came from, so evidence about one does not transfer to the other.
Ghrelin
The hunger hormone. Some growth hormone compounds work by copying it, so they can make you noticeably hungrier.
GHRH
A natural signal telling the pituitary gland to release growth hormone. Several compounds copy it.
GHRP
A second, separate signal that also triggers growth hormone release, through a different door than GHRH. This is why the two types are often used together.
GLP-1
A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
Growth hormone secretagogue
A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
Half-life
How long a compound stays active in your body. A longer half-life means you inject less often.
HPLC
A lab method that separates out everything in a sample so the amounts can be measured. It shows how much of the main ingredient is there. It does not confirm that the main ingredient is the right molecule.
In vitro
Done in a dish or a test tube, on cells outside a living body. It is the earliest kind of evidence there is.
Injection site
The spot on the body where you inject. Moving it around gives the skin and fat underneath time to recover between doses.
Intramuscular (IM)
An injection into a muscle, using a longer needle.
Intravenous (IV)
An injection into a vein. It needs training and equipment and is not something to do at home.
Investigational
Still being tested in clinical trials and not yet approved or legally sold for general use.
Lyophilized
Freeze-dried into a powder so it keeps longer. That is the white cake or dust in the bottom of an unmixed vial.
Mass spectrometry
A lab method that weighs molecules to confirm what they are. HPLC answers how much is in the sample. This answers what it is.
mcg and mg
Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
Myostatin
A natural brake on muscle growth. Several compounds are built to block it, though human results have been far smaller than the animal work suggested.
Off-label
A doctor prescribing an approved drug for something other than its approved use. This is legal and common, and it is different from a compound having no approval at all.
Orphan drug designation
A status given to treatments for rare conditions to make them worth developing. It is an incentive, not an approval, and a compound can hold it while being approved for nothing.
PCAC
The FDA advisory committee that reviews compounding ingredients. It recommends. It does not approve, and the FDA does not have to follow what it says.
Peer review
Other scientists checking a paper before a journal publishes it. It filters out some bad work. It does not make a finding true.
Peptide vs small molecule
A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
Placebo
A dummy treatment given for comparison. Without one it is very hard to tell a real effect apart from expectation and time passing.
Purity
The share of a sample that is the intended compound, usually given as a percentage. A high purity number on the wrong molecule is still the wrong molecule.
Randomized
Deciding by chance who gets which treatment, so the two groups are comparable. Studies that skip this are much easier to read the wrong way.
Receptor
A docking point on a cell that a compound attaches to. If a cell has no matching receptor, the compound does nothing to it.
Reconstitution
Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
Research only
No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
Stack
Using more than one compound at the same time. Almost no combinations have been tested together in people, so a stack is usually built on guesswork.
Sterile water
Water with nothing added to stop bacteria growing. It works for a single dose, but a vial mixed with it should not be kept and used again.
Subcutaneous
An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
Titrate
Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
Trial phases
The stages of human testing. Phase 1 checks safety in a small group, phase 2 looks for an effect, and phase 3 tests it against a comparison in a large group.
Units (on the syringe)
The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
