Product Summary
"MUTHA - No. 1 Serum" is effective for: Evens skin tone, Anti-aging, Moisturizing and Anti-blemish
Ingredient callouts
- A good concentration of Niacinamide (1.40% - 2.10%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Humectants (sodium hyaluronate crosspolymer 0.90% - 1.30%, sodium hyaluronate 1.10% - 1.60%, sodium acetylated hyaluronate 0.55% - 1.25%, polyglutamic acid 0.15% - 0.65% and glycerin 4.70% - 7.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide, tetrahexyldecyl ascorbate.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ferulic acid.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
A potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide, tetrahexyldecyl ascorbate
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: ferulic acid, glycyrrhiza glabra root extract.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, polyglutamic acid.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: oryza sativa bran oil, pentylene glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
