Valinta: Sodium Lauryl Sulfoacetate eli SLSA

SLSA is a gentle surfactant derived from coconut and palm oils. According to Ecocert natural and cosmetic standards, it is 100% of natural origin.

Sodium Lauryl Sulfoacetate (SLSA) – Its name resembles the harsher Sodium Lauryl Sulfate (SLS), but they are completely different substances.

SLSA is a gentle surfactant derived from coconut and palm oils. Unlike SLS, it does not dry out the skin or irritate sensitive skin, making it suitable for all skin types.

Key properties of SLSA:

Gentle yet effective cleansing: Removes dirt and excess oil without stripping the skin.
Rich foam: Produces a dense, creamy lather for a pleasant and luxurious cleansing experience.
Skin-friendly: Far less irritating than SLS.
Versatile: Widely used in cleansers thanks to its mild foaming ability.

Important note: Many confuse SLSA with SLS due to the similar name, but they are chemically and functionally very different. SLSA is a gentle, safe alternative suitable even for sensitive skin.

Summary: SLSA delivers gentle, effective cleansing with a rich, luxurious foam.

No Niin Cosmetics serums are incredible. The texture is absolutely lovely and they absorb extremely well. They wonderfully activate and stimulate the skin. I’ve become a regular user. The texture is perfect for my skin, and the hydration is more than sufficient. I can't wait to see what other amazing products this brand will release ❤️ It's unbelievable that over 98% of the ingredients are sourced from Finland!

Anti-Age Serum: A lighter texture that leaves a pleasant feeling on the skin without any oily residue. It’s almost as if wrinkles smoothed out after just a few weeks of use.

Moisturizing Serum: Leaves a wonderfully hydrated feeling on the skin without being sticky. After use, my skin felt more supple and moisturized and appeared more even. Now that it’s finished, I notice a clear difference in my skin.

Kati

The serums have been more than good; they are the best in my opinion!

I have been using them daily, both morning and night.

I love using oil serums, but instead, I’ve been using these serums, and I would gladly use them for the rest of my life.

They soothe my red skin so much and immediately provide that wonderful feeling of hydration.

No tightness at all, and my skin clearly calms down.

In my opinion, the texture and absorption—everything—is truly, really perfect.

Marjuska

My skin has clearly become more radiant, and fine lines have smoothened out. It works well for sensitive skin too, causing no unwanted reactions.

The texture is wonderfully rich.

The effects were most noticeable when the serum ran out, and I had to switch back to another serum.

After that, my skin felt tighter, and a certain radiance disappeared

The first test serum for aging skin felt great and even smoothed out forehead wrinkles. It absorbed quickly and didn’t feel sticky.

The second serum, meant for dry skin, has also been nourishing my skin well and has helped with milia. The testing continues! 😊

It has also helped my husband with the stubborn dryness on his forehead! 👍

Elvi tried No Niin Cosmetics' Aika Anti-Age Serum and fell in love with it.

Feels really good on the skin. Not too oily and absorbs well. Absolutely wonderful – my new favorite serum!

Hannele and her daughter tested No Niin Cosmetics' serums.

AIKA Serum:

"After just the first use, my skin felt smooth and hydrated. Dry, flaky areas disappeared completely, and my skin looks healthy again. The scent has a lovely oat-like aroma! The texture is pleasant, and the product comes in a beautiful glass bottle."

RAUHA Serum:

"My daughter's atopic skin has calmed down significantly. The individual dry, irritated spots on her face have soothed, and even makeup no longer irritates her skin as much when this serum is used as a base."

Hannele/@_hanscu_

Especially during the winter season, my facial skin becomes dry and flaky. As part of a collaboration, I chose to use No Niin Cosmetics' KASTE Bi-Phase Hydrating Serum. I haven’t made any other changes to my skincare routine, and within just a week, the flakiness and dryness have disappeared. This serum is here to stay as a part of my skincare routine! ✨

Do the products contain preservatives?

Yes. We use Geogard, a preservative that is COSMOS and ECOCERT certified. When a product has a water base, adding a preservative is necessary to ensure the safety and quality of the product. You can read more about the preservative we use here!

What is a bi-phase serum?

A bi-phase serum is a two-part skincare product that contains both an oil and a water base. Before use, the serum is shaken to mix the two phases. Bi-phase serums do not require emulsifiers, which are typically used to combine water and oil. Because a bi-phase serum does not need emulsifiers, the amount of active ingredients in the product is higher. The oil locks in moisture, while the water-based part hydrates and refreshes the skin.

Why do different products contain the same ingredients?

Many of the ingredients we use offer multiple benefits for skincare. For example, black currant seed oil has moisturizing, antioxidant, and soothing properties. Each serum is carefully formulated with ingredients that work perfectly together to achieve the desired effect. By using the same ingredients, like black currant seed oil, in different concentrations, we can tailor the serums to meet various skincare needs. A higher concentration may focus on intense hydration and skin protection, while a lower concentration can provide lighter care. This way, we ensure that each serum supports the skin's natural balance and provides diverse benefits in just the right way.

Is it normal for there to be particles in the serum?

Yes, it's completely normal! Sometimes, small plant particles may appear in the serum, and this is entirely natural.
