Address the appearance of individual blemishes with Medik8’s Blemish SOS.

This fast-acting treatment gel has been expertly formulated with potent salicylic acid (2%) to effectively and quickly reduce the appearance of blemishes and calm visible redness for a clearer, healthier-looking complexion.

Completely invisible and quick-drying, this targeted treatment gel is perfect for use at home or when you’re on-the-go. It can also be applied underneath or over your makeup.

Key Benefits:
Fast Action on Blemishes
Works fast to visibly reduce existing blemishes while helping to reduce blemish-causing bacteria.

Visibly Clearer, Calmer Skin
Calms visible redness and decongests the complexion to promote visibly healthier, clearer-looking skin.

Works Under or Over Makeup
The fast-drying, invisible formula remains undetectable both under and over makeup.

Key Ingredients:
Salicylic Acid (2%)
Exfoliating and decongesting from within the pore, this BHA breaks down any clogged oil and skin cells that can contribute to blemishes and enlarged pores.

Niacinamide
Also known as vitamin B3, niacinamide has anti-inflammatory properties that work to visibly calm blemish-induced irritation while supporting the skin’s natural barrier for a hydrated complexion.

Azelaic Acid
Featuring powerful antibacterial benefits, it helps to target blemish-causing bacteria and prevents new ones from forming.

Dioic Acid
Decongests and controls the amount of excess oil produced by the pores - helping to prevent future imperfections and blemishes.

Rated 4 out of 5 by from Blemish SOS Gel [This review was collected as part of a promotion.] Probably the only anti-blemsh product that actually works on my hormonak skin. I tried loads of different breakouts poducts and this one is definitely a winner. It's a clear gel and it smells like a pain relief ointment but it's tolerable, dries pretty slowly though, I must admit, and is very potent! Therefore after some trials I decided it's better to use it as the last step of my bed-time routine over the moisturizer and very precisely on the spots otherwise it might literally burn the skin. It's peeling like crazy next day but there will be no redness, itching or a visible scarring in the morning. 2-3 night applications and the red bump just vanishes. It's a wonderful product if you figure out how to use it properly.

Rated 5 out of 5 by from The best blemish treatment! [This review was collected as part of a promotion.] I have tried many products for reducing blemishes and this is by far the best. It helps soothe and reduce redness overnight, and can be used under makeup. This is my go to treatment as soon as I feel a breakout.

Rated 5 out of 5 by from Blemish SOS [This review was collected as part of a promotion.] Highly recommend, the SOS is highly affective, has helped reduce my breakouts significantly, I use alongside the blemish pads. Both together is a dream

Rated 5 out of 5 by from A must have product if you ever get blemishes [This review was collected as part of a promotion.] This is the only product that works as soon as I feel a blemish coming. It is my go-to and I have to replace it before I run out so I'm never without it.

Rated 5 out of 5 by from Amazing product [This review was collected as part of a promotion.] This blemish SOS is incredible, it works really quickly and also smells amazing. I’ll definitely repurchase when I run out!

Rated 1 out of 5 by from Doesn’t work [This review was collected as part of a promotion.] The first medik8 product I haven't liked! This didn't do anything for me other than dry out my skin, leaving flakes and spots rather than just spots. Got better results from supermarket spot creams for teenagers.

Rated 3 out of 5 by from This is alright but tbf [This review was collected as part of a promotion.] This is alright but tbf I hadn’t noticed a difference. And I feel like a clearasil one would do the same for a fraction of the price . Odd as I love the other products
