Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Antioxidant, Bleaching, Skin Conditioning

Arbutin is derived from the bearberry plant. It helps even out skin tone and reduce hyperpigmentation.

This ingredient has the ability to block tyrosinase, an enzyme that starts the process of skin darkening. When applied to the skin, arbutin works at a slow pace. This can make it less irritating than similar ingredients.

Kojic Acid is a similar ingredient.

Smoothing

Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging.

And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.

You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.

In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it.

If you are experiencing flaking, irritation, and dryness with this ingredient, be sure to double check all your products as this ingredient can be found in all categories of skincare.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

When you apply niacinamide to your skin, your body converts it into nicotinamide adenine dinucleotide (NAD). NAD is an essential coenzyme that is already found in your cells as "fuel" and powers countless biological processes.

In your skin, NAD helps repair cell damage, produce new healthy cells, support collagen production, strengthen the skin barrier, and fight environmental stressors (like UV and pollution).

Our natural NAD levels start to decline with age, leading to slower skin repair, visible aging, and a weaker skin barrier. By providing your skin niacinamide, you're recharging your skin's NAD levels. This leads to stronger, healthier, and younger looking skin.

Another name for vitamin B3 is nicotinamide. This vitamin is water-soluble and our bodies don't store it. We obtain Vitamin B3 from either food or skincare. Meat, fish, wheat, yeast, and leafy greens contain vitamin B3.

The type of niacinamide used in skincare is synthetically created.

Antioxidant

Kojic acid comes from fungi and can also be from fermented foods. It helps even out skin tone and reduce hyperpigmentation.

This ingredient works by blocking tyrosine, an enzyme that starts the process of skin darkening.

Kojic Acid is antifungal and often used to treat fungal infections. Additionally, it can help fight bacteria with its antimicrobrial properties. This can help treat acne as well.

A similar ingredient is arbutin.

i’ve been using this product everyday for a month and it works wonders. it has pretty much cleared almost all of my hyperpigmentation around my mouth. however my dark spots are fading much slower but still fading faster than when i’d any other dark spot correcting serum. i’m also using it on my under eyes but it seems like it is not working on that area

i would 100% recommend this product. but Show more

(Tried Nov 2022) One of the few brightening creams that I tried where I actually saw results. I only ever applied this as a spot treatment and not all over. Giving it 4 stars because I did find it slightly irritating and the smell was rather strong, so I ended up switching over to applying it as needed. I think the $18 Mini version was more than enough for me!

give it time to fade dark spots-glowy skin comes faster
Love this product. I was worried about all the actives in it because of my sensitive skin, but I had no reactions or breakouts. It takes some time to fade dark spots & acne scars but after a few weeks (3-4) they should be noticeably lighter or almost gone. I noticed my skin seemed glowier and more clarified within a week or two. No noticeable Show more
