Dear Internet, Retinoids Don’t Thin Your Skin

Dear Internet: no, they don't. Here's what's actually happening.

Retinoids do not thin your skin. They thin the stratum corneum — the outermost layer of dead cells — while thickening the living epidermis and dermis beneath it. The myth confuses surface shedding with structural loss. They are not the same thing. Retinoids make skin firmer, not weaker.

Vivant Skin Care was founded by Dr. James E. Fulton, co-developer of the original Retin-A. Few brands understand vitamin A more intimately. So let us be clear.

The confusion is understandable. Retinoids cause visible peeling and shedding, especially in the first weeks. Skin looks and feels different. People read that shedding as damage.

It isn't damage. It's renewal.

Skin is a structure — layer upon layer of cells, tissue, and fat that support and protect. There are three main layers:

• The epidermis, the outer layer, which includes the stratum corneum.
• The dermis, home to collagen, elastin, sweat and sebaceous glands, hair follicles, nerves, and blood vessels.
• The hypodermis, mostly structural fat and connective tissue.

Each holds sublayers of its own. All of the cell-renewal action happens in the epidermis.

Cells begin deep in the epidermis at the stratum basale. They mature, rise toward the surface, die, and shed — a cycle that takes about thirty days. The stratum corneum is the final stop: a compacted layer of dead keratinocytes.

Age and UV exposure slow this shedding. The layer thickens and grows uneven. The result is skin that looks dull, heavy, and dry. A thinner, more even stratum corneum looks the opposite: clear, luminous, awake.

Retinoids accelerate cell renewal. They move fresh cells to the surface faster and shed the excess more efficiently. The stratum corneum thins — because the dead layer is finally doing what it's meant to do, only better.

This is the "thinning" the myth refers to. It is the thinning of dead skin. Nothing structural is lost.

Below the surface, retinoids do the opposite of thinning. In the lower epidermis and the dermis, they encourage cell proliferation, support collagen and elastin production, and improve circulation. Peer-reviewed research links retinoid use to a measurable increase in skin thickness and a firmer dermal structure.

Translation: thinner where you want less. Thicker where you want more.

Retinoids don't thin skin. They refine the surface and strengthen the foundation. That isn't damage. That's the point.

Vivant formulates with retinyl propionate — our REt (RP)™ Retinoid — a form of vitamin A chosen for its results and its tolerability. The myth can rest now.

Derm-a-renew pairs Peptides with our REt (RP)™ Retinoid to refine the look of fine lines, uneven tone, and texture — gently. Made for skin that's new to retinoids, easily reddened, or simply asking for more care. The two actives work in tandem to revitalize while protecting hydration and minimizing the irritation retinoids are known for.
