OS-01 (Peptide 14)

Human clinical Skin & Hair 3 sources

OS-01, also known as Peptide 14, is a proprietary senotherapeutic peptide developed to target skin aging at the cellular level. Research indicates it reduces the accumulation of senescent cells, improves skin barrier function, and promotes overall skin rejuvenation and health.

02Mechanism of action

Senescence Modulation

OS-01 targets and reduces the burden of senescent (aging) cells in the skin.

Cellular Rejuvenation

It decreases senescence markers and promotes healthy cell function, improving epidermal thickness and collagen production.

Skin Barrier Enhancement

This leads to improved skin barrier function, reduced visible signs of aging, and potentially lower systemic inflammation markers.

03Human evidence

Improved skin barrier function and reduced systemic inflammation markers.

A 12-week pilot clinical trial evaluating the topical formulation of OS-01 in human subjects.

Improved skin evenness, radiance, pores, and firmness in 95.5% of users.

Clinical investigation of OS-01 face topical supplement assessing visible skin aging parameters.

04Preclinical evidence

Decreased cellular senescence induced by chronological aging, UV radiation, and progeria models.

In vitro studies using human dermal fibroblasts and 3D human skin equivalents.

Promoted tissue rejuvenation and reduced biological age markers.

Ex vivo skin biopsies and 3D skin models treated with Peptide 14.

05What is known vs. unknown

Reasonably established

OS-01 is a senotherapeutic peptide designed to target senescent cells.
It has been shown to improve skin barrier function and reduce visible signs of aging.
Preclinical studies demonstrate its ability to reduce cellular senescence burden in skin models.
It is primarily used as a topical formulation in skincare products.

Unknowns & limits

Long-term systemic effects of prolonged topical use are still being studied.
Its efficacy compared to prescription retinoids or other established anti-aging treatments requires more direct comparative trials.

06Safety & regulatory context

Regulatory statusOS-01 (Peptide 14) has been shown to be safe in in vitro and in vivo toxicity assessments. It is currently available as a cosmetic topical ingredient in commercial products and is not regulated as a prescription drug by the FDA. Known side effects are minimal, primarily limited to potential mild skin irritation typical of topical products, though it is generally well-tolerated.

07Compared with GHK-Cu (Copper Peptide)

OS-01 (Peptide 14) vs. GHK-Cu (Copper Peptide)

Key difference

OS-01 specifically targets cellular senescence (senotherapeutic), whereas GHK-Cu primarily focuses on stimulating collagen production and wound healing.

When researchers discuss each

OS-01 is discussed in the context of reducing biological skin age and senescent cell burden, while GHK-Cu is highlighted for tissue repair and collagen synthesis.

08Glossary

Senescent cells

Cells that have stopped dividing but do not die, often secreting inflammatory factors that contribute to aging.

Senotherapeutic

A class of compounds that target cellular senescence to delay or reverse age-related dysfunction.

Fibroblasts

Cells in connective tissue that produce collagen and other fibers.

GHK-Cu

Skin & Hair

Human clinical

GHK-Cu is a naturally occurring copper complex first isolated from human plasma. Research shows it plays a significant role in promoting wound healing, stimulating collagen synthesis, and modulating gene expression to support tissue repair and anti-aging processes.

1-2 mg/day (SubQ) or 1-3% concentration (topical)

Acetyl Octapeptide-3 (SNAP-8)

Skin & Hair

Human clinical

SNAP-8 (Acetyl Octapeptide-3) is a synthetic octapeptide designed as an elongated, more potent version of the popular hexapeptide Argireline. It functions as a topical "Botox-like" peptide by modulating the SNARE complex to reduce the release of acetylcholine, thereby relaxing facial muscles and reducing the depth of expression wrinkles.

Melanotan II

Skin & Hair

Human clinical

Melanotan II is a synthetic analog of the alpha-melanocyte-stimulating hormone (α-MSH). It was originally developed to induce skin pigmentation (tanning) to protect against UV radiation, but research also demonstrated significant effects on sexual arousal and erectile function.
