Is it okay to use niacinamide and VC together?

Dec 29,2021 | HISEEK PRETTY

Q1: My question is about "skincareskool", which is described as the first algorithm to compare two similar products, is it reliable? Do you think that products with high matching scores will have similar results?

A: They give reasonable options to choose from, it's just important to know that they are not completely accurate either.

Q2: Shilpa said, "I learned online that certain actives cannot be used together, especially niacinamide and VC. I read that VC reacts with niacinamide and prevents its activity, is this true? If this is true, should I rotate my creams with niacinamide and VA at night? Can I use them together, or will the two react as well?

A: It is now possible to use both ingredients in the same product. Generally speaking, VC is effective in the low PH range, while niacinamide is more effective in the slightly higher PH or neutral PH range, so it will be a question of whether the PH is optimal. In terms of the above question, this is not an issue. In the 1960s there was some research that proved that niacinamide and VC have a negative interaction (they may react to produce niacin when the skin is red and itchy), however, this result was obtained by reacting niacinamide with pure VC at higher temperatures). The current formulation is not subject to such problems at room temperature storage conditions.

So would there be any benefit to using these two together? You can get more benefits from a single product. Niacinamide and VC can address different problems caused by skin aging. Theoretically, they can also brighten the skin when used together, as they can take different paths to achieve this effect.

Q3: Paige asked: "Is there a difference between the anti-blue light antioxidant serum sold in the market and a good antioxidant serum? Do these products have actual efficacy? What are their drawbacks?

A: It's not a formulation difference, they almost all use anti-aging ingredients, such as peptides, moisturizers, niacinamide, etc. But these ingredients that form the formula, do not have a metric that can measure the effect of blue light on the skin. These products are beneficial as moisturizers, but there is no measurable difference in terms of anti-blue light.

Q4: Mishu asks: "Is it worthwhile to obtain and use plant extracts in skincare products? Would synthetic ones be a little better?

A: It's all about whether the plant extracts are useful for your skin. As a consumer, you need to know upfront that cosmetic distributors will advertise their products as having botanical extracts in their products when in reality there is only a very small amount added to the product, and these ingredients are called claimed ingredients that help them make up a story. They don't make the product effective.

Currently, there are many plant extracts that may have an effect, such as aloe vera these plant extracts have a moisturizing effect. There is an article titled "Phytodermatology: An Evidence-Based Review" published in the Journal of Clinical Dermatology where they point out that some plant extracts are beneficial, such as tea tree oil for acne and licorice from licorice for atopic dermatitis and psoriasis. Of course, for these effects, they have direct evidence. It's not at a treatable level yet.

Q5- Alison asks, is it okay for me to use old-fashioned Vaseline and glycerin on my face? Is hyaluronic acid just a fad?

A: Yes, glycerin is the most moisturizing moisturizer, although hyaluronic acid can make up a good story. I think hyaluronic acid is merely a fad, though, as it stays on the skin it may be effective. I don't think it will work much better than regular glycerin. But it's hard to market a product with just it, which is why I don't do business in beauty products. If you use a product with Vaseline and mineral oil, you couldn't do better in terms of performance.

Q6 - What is the deal with prostaglandins used in eyelashes? My understanding is that it is similar to a prescription drug in terms of effectiveness and side effects, but does not require labeling or testing of the "drug". What is the situation?

A: If they work, then they are illegal drugs, except for Latisse (an FDA approved drug made by Allergan to promote longer and thicker eyelashes)

Q7-Tina asked "Monat has a list of products they do not use: Nipagin-free, SLS/SLES, cyclic silicones, BHT, DEA, phthalates, phenoxyethanol, petroleum jelly, mineral oil, paraffin, triclosan, plastic microspheres, formaldehyde releaser. Can you explain in these terms they are harmful? Or are they based on market needs?

A: I am afraid they are based on the market.

Q8-Kimberly-What is the difference between pharmaceutical-grade skincare products and over-the-counter skincare products? I've heard many experts say that non-medical grade skincare products don't help unless the skin itself is fine.

A:Over-the-counter cosmetic treatments like acne, psoriasis, eczema, etc. have been shown to be effective. These ingredients and claims are regulated by the FDA (at least in the US). In this case, OTCs are considered to be over-the-counter drugs. In the market they are considered the most compliant cosmetic type of product. If you can only buy the items in pharmacies or grocery stores, then you are probably referring to OTC brands of cosmetics. They are different in the sense that legally they cannot treat diseases. They are classified as cosmetics and are only allowed to improve the appearance of skin and hair.

Pharmaceutical-grade skin care products are a market niche that has no legal meaning. Anyone can call them "pharmaceutical grade". It does not mean a medicine prescribed by a dermatologist. It is generally a cosmetic product sold by dermatologists under the name of a dermatologist or simply

A marketing strategy. The reality is that there is no special technology that makes this type of cosmetic better than other levels of skincare for treating disease, it is just marketing, that's all.
