Osmosis StemFactor MD is a growth factor serum built on human stem cell conditioned media and exosome technology. The MD Advanced formula carries over 600 growth factors and skin proteins, and each bottle is research-proven to hold 3.5 trillion exosomes, the highest concentration Osmosis produces.

What Is StemFactor MD?

StemFactor MD is the professional tier of Osmosis's growth factor line. Growth factors are the signalling proteins that tell skin cells to repair and renew. As skin ages, its natural supply falls. StemFactor MD delivers these proteins from stem cell and fibroblast conditioned media, the fluid these cells release, rather than from the cells themselves.

How the Growth Factor Serum Works

StemFactor MD uses exosome technology to carry its active proteins into the skin. Exosomes are tiny vesicles that cells use to pass instructions to one another. Osmosis uses them as delivery vehicles, so the 600-plus growth factors reach the skin in a form it recognises. The serum targets the appearance of aging and past damage by supporting the skin's own repair signalling.

What Is in StemFactor MD?

The MD formula is short and active-led.

• Human stem cell conditioned media and human fibroblast conditioned media are the source of the growth factors and proteins
• Exosome technology delivers those proteins into the skin
• Witch hazel tones
• Phosphatidylcholine supports absorption
• Lactic acid appears in the MD formula for gentle surface renewal
• Preserved with dehydroacetic acid and benzyl alcohol

The formula is fragrance-led only by a trace of lemon peel oil. It contains no synthetic fragrance, no parabens, and no sulfates.

Who It Is For

Choose StemFactor MD if your priority is the appearance of aging skin, loss of firmness, or the visible effects of past damage. Osmosis lists it as suited to aging, sensitive, irritated, and pigmented skin. It also suits skin prone to redness, which is why rosacea-prone users are among those it is formulated for.

Look at a targeted active instead if your main concern is a single issue like pigmentation or breakouts, where a focused serum from the Serums range may fit better as a first step.

How to Buy: Consultation First

StemFactor MD is part of the Osmosis MD Advanced collection, which Osmosis sells only through trained professionals. That is why SkinSkulpt requires a short consultation before your first order. Request the product on this page, and a team member will reach out to confirm the fit and complete the purchase. The consultation exists to match the MD formula to your skin, not to slow you down.

How to Use StemFactor MD

Apply one to two pumps to clean skin, morning and evening. Follow with any additional serum and a moisturiser. Apply the excess to the back of the hands. Browse the full Osmosis range for products that layer with it.

FAQs

Why does StemFactor MD require a consultation?

Osmosis sells its MD Advanced collection only through trained professionals, so SkinSkulpt arranges a short consultation before a first purchase. Request the product on this page and a team member contacts you to confirm the formula suits your skin. The step matches the product to your needs rather than delaying the order.

What are growth factors and exosomes in StemFactor MD?

Growth factors are signalling proteins that direct skin cells to repair and renew. Exosomes are the vesicles cells use to deliver those signals. StemFactor MD supplies over 600 growth factors from human stem cell conditioned media, carried by 3.5 trillion exosomes per bottle, the highest concentration in the Osmosis line.

Is StemFactor MD suitable for sensitive or rosacea-prone skin?

Osmosis formulates StemFactor MD for aging, sensitive, irritated, and pigmented skin, and lists it among options for skin prone to redness. The consultation before purchase covers suitability for your specific skin. Patch testing and professional guidance matter more for active growth factor formulas than for everyday serums.
