What Is Lactobacillus/Pig Placenta Ferment Filtrate?
Lactobacillus/Pig Placenta Ferment Filtrate is a fluid obtained when pig placenta is fermented with friendly Lactobacillus bacteria, then filtered to leave a clear active liquid. Pig placenta is rich in proteins, amino acids, vitamins and trace minerals while the Lactobacillus fermentation step breaks these large molecules into smaller parts that skin can more easily use and also produces skin-loving compounds such as lactic acid and short-chain peptides.
The idea of using placenta in beauty dates back decades in Japan and Korea where spas offered “placenta facials.” As clean beauty and fermentation trends grew, formulators combined placental extracts with probiotic fermentation to create a milder odor, better stability and improved absorption, which led to the modern ferment filtrate now seen in skincare.
Production starts with medical-grade placentas collected as a by-product of the food industry. They are thoroughly screened, disinfected and placed in a nutrient solution with selected Lactobacillus strains. Over several days the bacteria digest and transform the raw material, after which the mixture is carefully filtered to remove solids and live microbes, yielding a clear filtrate that meets cosmetic safety standards.
You will most often find Lactobacillus/Pig Placenta Ferment Filtrate in sheet masks, hydrating serums, anti-aging creams, brightening essences and leave-on treatments aimed at restoring glow and suppleness.
Lactobacillus/Pig Placenta Ferment Filtrate’s Cosmetic Benefits/Uses
This ingredient is prized for one main job in skincare
Humectant: it attracts water from the environment and pulls it into the upper layers of skin helping to keep the surface moist and plump. Better hydration softens fine lines, improves elasticity and boosts the overall comfort of dry or stressed skin. The small peptides and lactic acid created during fermentation can also support a smoother skin texture and a fresher look.
Who Can Use Lactobacillus/Pig Placenta Ferment Filtrate
This ferment filtrate is generally well tolerated by all skin types including dry, normal, combination and oily because its main job is to bind moisture without leaving a heavy film. Sensitive skin usually handles it well thanks to the gentle nature of fermented ingredients, though anyone extremely reactive to animal proteins should approach with caution. Acne-prone users appreciate that it is lightweight and water based so it is unlikely to clog pores.
Because it is derived from pig placenta it is not suitable for vegans or vegetarians who avoid animal-derived ingredients. People who follow a cruelty-free philosophy but still use by-products of the food industry may personally decide whether they are comfortable with its origin.
There is no research suggesting topical placenta ferment harms pregnant or breastfeeding women, yet the hormonal origin can feel unsettling. This is not medical advice and expectant or nursing mothers should show the product to their healthcare provider before use just to be safe.
The ingredient does not increase photosensitivity so there is no special need for additional sun precautions beyond your usual SPF routine.
Potential Side Effects/Adverse Reactions
Side effects from topical Lactobacillus/Pig Placenta Ferment Filtrate can vary from person to person. The points below describe potential reactions but most users will not experience them when the product is correctly formulated and applied.
- Allergic reaction – rare itchiness redness or swelling in those sensitive to animal proteins or fermentation by-products
- Contact dermatitis – possible stinging or rash if the skin barrier is already compromised
- Breakouts – in very oily skin a new humectant layer can occasionally trap sebum and lead to small pimples
- Eye irritation – mild watering or burning if the serum or cream accidentally gets into the eyes
If any of these effects occur stop using the product and consult a healthcare professional to determine the cause and proper treatment.
Comedogenic Rating
Rating: 0 on the 0-5 scale. Lactobacillus/Pig Placenta Ferment Filtrate is a lightweight water based humectant with no oily or waxy residues so it does not block pores. Its molecules are small peptides, amino acids and lactic acid which readily dissolve in water and rinse away cleanly. This makes it suitable for acne-prone or breakout-prone skin. Only if a finished formula pairs it with heavy oils or occlusives might pore clogging become a concern.
Summary
Lactobacillus/Pig Placenta Ferment Filtrate works mainly as a humectant that pulls moisture into the upper skin layers. Fermentation breaks down placenta proteins into mini peptides and forms lactic acid, both of which help skin stay hydrated smooth and supple. Although placenta based actives have a long history in East Asian beauty they remain a niche choice in global markets, attracting users who love probiotic and K-beauty trends while being avoided by strict vegans and some mainstream brands.
Topically it is considered low risk with a very low comedogenic rating and only rare sensitivity reports. As with any new skincare ingredient it is wise to patch test a fresh product first to make sure your skin is happy before applying it to a wider area.
