The Allies Difference

Product information

The perfect brightening formula does exist – no exfoliation needed.

Combining proven brighteners with modern-day clinically backed antioxidants, we've developed our ultimate solution for those dreaming of luminous skin without the effects of exfoliants and reduced risk of irritation.

We added Diacetyl Boldine & Licorice Complex and a Red Algae & Pea Complex for enhanced effects on evening dullness, increasing luminosity, preventing and fading the appearance of dark spots.

Even when your skin is sensitized, our serum is the perfect way to help strengthen and support your complexion. Tranexamic Acid helps support the skin barrier, while brighteners and peptides supercharge radiance and firmness. With its liquid-soft, smooth texture, this serum sinks easily into the skin.

AM + PM, after cleansing and misting, apply 1-3 pumps over the face and neck area. Follow with your favorite Allies of Skin moisturizer and The One SPF 50.

BEST SERUM FOR HYPERSENSITIVE SKIN

I purchased this product twice. I have rosacea prone skin and I choose my serums very carefully. This is this best serum for hyperpigmentation on my skin as it does not trigger rosacea and gives my the results i wanted.

REALLY WORKS!

This is a repeat buy for me. Unfortunately my skin is too sensitive for the vitamin C serum so I’m really happy to have found this!

This is by far the best dark spot serum I have ever tried. I will buy four bottles at a time because this is a product I simply can’t go without. I am Fitzpatrick Type 5, and in being so, am prone to hyperpigmentation. I’m an avid user of sunscreen and vitamin c, however in using them alone is still not quite enough for my skin. When using this serum alongside vitamin c and sunscreen, my skin glows like no other. I will repurchase this product over and over.

In love

I have been using this serum for a month now and I am loving it. It is not harsh on the skin (no irritation) and my dark spots look a little bit lighter. It’s too early to see a dramatic change but I am sure that consistency will pay. Overall very satisfied with this product.

Dependable product

I am a dark skinned Black woman and started using this last year. On my 3rd bottle now because this consistently shows me results! My skin is smooth, radiant, and perfectly plump.

Nice product!

Overall, I like this product but it seems to take a while to see results. I’m excited though!
