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.

Good to Know:
FRAGRANCE FREE
NO SYNTHETIC COLOURS
PARABEN FREE

Directions

Step 1

Step 2

Rated 4 out of 5 by from Liked it. Breakouts can be so annoying but I found this to be helpful if used as soon as I could feel a spot beginning.

Rated 5 out of 5 by from Quick So far I’ve been so impressed by this - I find if I have a new blemish - if I put this on, the next morning it is already reduced and usually gone completely within a few days!

Rated 5 out of 5 by from Fast acting and only need a tiny amount I love this little tube — it works quickly on any breakout without drying my skin out. You only need the tiniest bit and it starts calming redness within hours. Perfect to dab on under makeup or at night for quick results. A real skincare staple in my routine

Rated 4 out of 5 by from Start using it at first signs Good product, does the job. However you really need to start using it at very first signs of blemish appearance. Otherwise it doesn't really do anything if you start using it later on.
