Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.

Once applied, Tranexamic Acid starts decreasing inflammation from UV exposure. Tranexamic Acid also prevents our skin cells from meeting the pigment production cells.
Its brightening property makes it great at reducing the appearance of acne scars and marks.
Fun fact: Tranexamic Acid is also a medication used to reduce heavy bleeding.
This acid is derived from lysine, an amino acid.

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:

I'm very pleased with the results of this product. Within 2 weeks, it was able to remove most of the stubborn dark spots/scaring that was on my temple area. Despite having fragrance in the formulation, I actually didn't notice any irritation or breaking out after using it. It's nice that the product isn't too expensive either (Roughly $20 on Amazon when I purchased at the time) I also find the Show more
I’ve been using this for three months now on sensitive and reactive skin. I had no bad response, no irritation or breaking out. I use it both morning and night, and I believe some results are there - dark marks are slowly fading, and any spots I’ve had while using this leave less of a dark mark than they used to.

Did a patch test on my arm to see if it works for hyperpigmentation - tried for 3 days (once a day) and my arm had small pimples/ irritation bumps! I never have breakouts on my body.
Don’t know if the concentrations are too potent (even for the body) or the formulation is just bad.
I think this is one of the best serums for hyperpigmentation IF you are a BEGINNER (keep that in mind), I have sensitive skin and I find it very soothing but didn’t see much results.
Also this serum is quite sticky so I recommend you that after you apply it on your face, leave it for 10-15 minutes so your skin can fully absorb the product. Then you can use other products as you wish. Hope it Show more
