Solid Results, but Not a Must-Have

[This review was collected as part of a promotion.] This serum helps with active breakouts, but results aren’t instant and it takes consistent use to see improvement. While it does reduce redness over time, it can cause some mild irritation if used too often, especially on sensitive skin. The texture is lightweight, but it can feel slightly tacky before fully drying. It doesn’t leave a heavy residue, but I noticed a bit of shine after application, so it may not be ideal if you’re very oily (I am). The price is definitely high for the amount you get, which is a downside. The packaging looks nice and the dropper is convenient, but it’s easy to dispense too much product at once. Overall, it works, but it’s not a miracle product and may not be worth the price for everyone.

No irritation

[This review was collected as part of a promotion.] Non irritating serum that keeps acne at bay. This is great as a maintenance serum once acne has been cleared up. It doesn’t feel sticky and it glides on nicely.

Perfect for sensitive acne prone skin types

[This review was collected as part of a promotion.] Packing is super cute! I was a-bit skeptical of this serum working considering everyone on social media tends to always give products positive reviews instead of real reviews. With that being said it worked pretty well! I had a bit of a breakout and my acne is almost gone. It helped with irritation as well and helped any inflammation go away. It does have a slight weird smell to it but other than that it’s a 10/10

Works Great

[This review was collected as part of a promotion.] The product seems great as of right now I’ve been using it for a couple weeks and I do see some improvement and there isn’t much sense to the packaging or the product itself. It seems like it’s doing its job and it feels pretty good on the skin after you apply a moisturizer.

Works don’t try to put makeup on with it.

[This review was collected as part of a promotion.] Honestly it works I’ve noticed a difference in my skin. In my opinion it doesn’t really work under makeup this is a product I would put on at nighttime without putting makeup on.

Not my first choice

[This review was collected as part of a promotion.] This is a fine serum. I hesitate to trust Sunday Riley products because they use essential oils and some irritating ingredients. This serum did not make my face itchy, but I didn’t notice much in terms of acne treatment or prevention. There are better serums out there for less!

Great

[This review was collected as part of a promotion.] The packaging was great! I really enjoyed the texture. The scent was a little off but I can see there is a slight difference in my skin tone. I really have enjoyed this product.

Dies up your acne within a few uses

[This review was collected as part of a promotion.] This was a great product, in a glass bottle, the consistency was very smooth and it was very light. You’re supposed to add a light even layer to you face after you wash it. I’ve only used it a few times and it did make a difference in that little time. I can tell this product will work and it will last me probably close to a year. It fires up some of my active acne spots with one use.

This is one of the best products I’ve used in a wh

[This review was collected as part of a promotion.] I can’t even put into words how awesome this stuff is. I have noticed such a big difference in my skin while using this product. It does burn a little bit, but I honestly don’t mind it if it’s making my skin better. It’s easy to use, and it doesn’t give me a headache with a strong scent. Overall recommend this so much.

I love this product!

[This review was collected as part of a promotion.] Okay, so I used this for the first time when I had a few acne spots during my period, and it helped me get rid of my acne during my period and it usually sticks around for much longer!
