The concept behind A-Silkne
Cosmetic Ingredient in the With-Covid-19 Era
With the emergence of COVID-19 pandemic, diverse crises modern consumers have encountered came to the surface. People’s fear of viruses and outside world has hit a peak, and psychological pain resulting from isolation has also increased. In the belief that it is our duty to reduce such anxiety and meet consumer needs, we have promoted R&Ds to provide more effective ingredients in a safe and secure fashion. To properly respond to new consumption patterns and consumer culture, in addition, we have tried to reflect the latest trends such as Clean Beauty and Sensory Cosmetics.
In makeup unlike skincare, visual effects including coloration, coverage and spreadability are important. Therefore, there have been some criticisms on the use of harmful ingredients. With the gradual spread of people’s perception of ‘body burden’ in makeup products, clean-beauty makeup products have already been successful abroad, especially in niche brands. I particular, there has been
a rising demand for ingredients which can substitute some controversial materials among base makeup ingredients such as silicon oil (dimethicone, cyclopentasiloxane, etc.) and PEG emulsifiers.
Are there any safe and reliable makeup products which can cover defects and, at the same time, reduce skin inflammation?
A-Silkne INCI
A-Silkne is a 100% natural plant-derived ingredient obtained with the optimum mixing ratio of heptyl undecylenate (from castor oil) and Magnolia officinalis bark extract. With this natural substance, we respond to consumer needs in the With-COVID-19 Era.
Heptyl Undecylenate
A very light and dry emollient extracted from castor oil. This soft and smooth oil can be a natural substitute for synthetic softeners such as cyclomethicone and mineral oil. It has oil formulation, but it is not greasy and keeps your skin smooth and flexible by preventing trans-epidermal water loss (TEWL).
Magnolia Officinalis Bark Extract
This extract is comprised of magnolol and nonokiol extracted from Magnolia officinalis bark. With powerful anti-inflammatory and antimicrobial effects, it is effective in treating acne-causing bacteria without skin irritation.

Causes of Acne and Alleviation
A-Silkne Test Data
1) Antimicrobial Effects of Magnolia Officinalis Bark Extract on C. Acnes
- Cultures C. acnes ATCC 6919 (acne-causing germ) in an anaerobic environment at 37℃ for 4-6 days
- Checks antimicrobial effects via a well-diffusion assay
→ Great antimicrobial effects on C. acnes confirmed even at low concentration (0.8%)
2) Antimicrobial Effects of A-Silkne on C. Acnes
- Cultures C. acnes ATCC 6919 (acne-causing germ) in an anaerobic environment at 37℃ for 4-6 days
- Checks antimicrobial effects via a well-diffusion assay
→ Compares antimicrobial effects on C. acnes with salicylic acid and Centella asiatica extract which are commonly used in acne care
→ Greater than salicylic acid and Centella asiatica extract in terms of antimicrobial effects on C. acnes
3) C. Acnes Elimination Effects in Oil Formulation
→ C. acnes eliminated 99.9999% in just two (2) days in oil balm
→ C. acnes not proliferated for one (1) month
4) Antiseptic Effect Test in Oil Formulation
→ Great antiseptic effects on bacteria in oil balm (99.9999% eliminated in the first week)
5) Inhibition of Proliferation of Mold on Makeup Puff
- A-Silkne 0% / 2% / 5% (in Sunflower oil)
- A. brasiliensis (skin microbial) injected and cultured for 2 months after applying the above three experimental groups to makeup puff evenly
→ The inhibition of the proliferation of mold on A-Silkne-applied makeup puff confirmed
6) Inspection of Fungi and Bacteria on the Surface of Oil Balm
- 2 different multi-balm products, oil balm base and oil balm on the market + 2% A-Silkne
- The above four experimental groups applied to skin multiple times and stored at room temperature for a day; then fungi on the product surface inspected by rubbing and culturing them on TSA (bacteria) and PDA (fungi) media
→ Able to prevent bacterial and fungal contaminations on oil balm with A-Silkne
→ A possibility of bacterial and fungal contaminations if ‘A’ and ‘B’ products on the market are continuously used
7) Feeling-after-Use Comparison
→ Improvements in spreadability, absorption, moisturizing and film formation with A-Silkne in comparison to oil balm (placebo)
→ With A-Silkne, improvements in feeling after use close to the level when the same amount of silicone oil is applied; feels fresher and softer
8) Safety (Single Patch Test)
A sample was patched on the back against 30 adult testees aged 20-60. In 24 hours, the patch was removed, and symptoms such as red spots and swelling were visually inspected. Then, test results were analyzed in consideration of primary cutaneous irritation index (PCI) and sample types.

A-Silkne Application
Salicylic acid used in acne care reduces acne symptoms by removing sebum and dead skin, not by inhibiting C. acnes. Therefore, it could cause dryness and irritation due to excessive peeling. With antimicrobial effects on C. acnes (refer to #2 test data), A-Silkne is even good for sensitive acne skin. In particular, it is applied to acne mark-covering products, preventing acne from recurring or worsening.
Wearing a mask for long hours can cause inflammation and irritation by disrupting skin breathing. In addition, clogged pores can develop into cysts. Friction with a mask impairs a skin barrier and worsens skin irritations, which is called, ‘Maskne (perioral dermatitis)’. In the With-COVID-19 Era when wearing a mask is critical, it is required to prescribe materials which can reduce skin burden.
Spot Patch#AcneCoverage #LongAnti-inflammatoryEffects
A spot patch is available in two different types: an acne patch applied onto acne, slowly alleviating the symptom; a patch used to prevent acne mark formation. It is anticipated that applying A-Silkne to spot patches would enhance antimicrobial and anti-inflammatory effects.
Stick Type Makeup / Skincare
In makeup products, stick types are common, including stick multi-balm which has recently earned a great popularity due to convenience of use, foundation, consealer and lipstick. These stick products are mostly made with oil so that they are low in water activity. As they are used repeatedly, bacteria become proliferated with contaminants such as dirt and sebum remaining on the skin. Therefore, anti-inflammatory substance is required to prevent skin irritations caused by repetitive exposure to bacteria and sebum.
Mascara & Lip Colors with Tip Applicator
#Lip&Eye #StickType #Makeup
Among color makeup products, mascara and lipsticks which are put back into a sealed container after use are vulnerable to bacterial growth. Since such products are applied onto sensitive eyes and lips, it is required to prescribe safer ingredients.
Makeup for Teenagers
In the past, in cosmetics specially produced for youth at stationeries and convenience stores, hazardous heavy metals were found. Since then, parents have closely watched the ingredients of cosmetics for their children. In addition, teens tend to share their items such as lip balm and tint with their friends and not pay too much attention to hygiene. Therefore, it is needed to watch them more carefully. Therefore, it is required to apply ingredients which are safe from external bacteria and contaminants to the makeup products for children and youth.
In sunscreen which is now essential all the year round and primers and fixers which enhance makeup adhesion and durability, safety and spreadability are important. In particular, primers which are used to fill gaps between pores can cause skin irritations. With the expansion of ‘clean beauty’, there has been a rising demand for ingredients which can substitute silicone or be used as boosters. It is anticipated that A-Silkne would reduce white cast formation in sunscreen and enhance feeling after use through improvements in spreadability.
Cleansing Oil#AcneSkin #CleanBeauty #Emulsifier
In the past, PEG and PPG surfactants which are cheap but have great emulsifying and cleansing effects were mostly used in cleansing oil. Recently, however, they have been replaced by better ingredients. In A-Silkne, heptyl undecylenate works as an emulsifier. With the anti-inflammatory effects of Magnolia officinalis bark extract, it isapplicable to the cleansing oil specially designed for acne and irritated skin.
