As a skincare aficionado, there’s nothing that makes me happier than finding a product that actually works for me, namely because as someone with rosacea, those finds can be few and far between.

If you’re looking for something to help sooth your inflamed, irritated skin and leave it less angry by morning, you’ll want to consider adding Peach Slices’ Redness Relief Azelaic Acid Serum to your routine. Because ever since I did, my skin has never been calmer.

The K-beauty brand’s serum has built a following among people dealing with rosacea, breakouts and general redness, and it’s easy to see why: it leans on a single, well-studied active ingredient instead of a long list of trendy extras.

The serum features 10% azelaic acid, an ingredient dermatologists have recommended for years for redness and acne. Peach Slices rounds it out with panthenol (pro-vitamin B5) and a blend of green algae extract and cica to help soothe irritation and support the skin barrier.

Best of all, the formula skips fragrance, alcohol and silicones, which matters for anyone whose skin reacts to those ingredients.

Using it is a breeze: simply apply one to two pumps to clean, dry skin after cleansing and toning, then follow up with moisturizer (and SPF if it’s a daytime step). It’s lightweight so it absorbs fast.

Why I love Peach Slices’ Azelaic Acid Serum

As someone who’s been dealing with rosacea since they were a teenager, I’ve tried many different products to treat it — prescription and OTC alike. This serum, however, is one thing my skin has adored since day one.

Now, everyone’s skin is going to react differently, but the reason this one sticks out to me is its blend of additional soothing ingredients. With the addition of panthenol, green algae and cica — all ingredients with soothing effects — this serum feels like a two-for-one of rosacea-fighting goodness.

Azaleic acid is also known to have a slight exfoliating effect, something I also adore as it helps keep my skin smooth and clog-free without irritating me. This also makes it something that layers well under makeup without pilling, too.

Basically, the Redness Relief Serum more than lives up to its name, and as someone who has been let down time and time again, it’s great having a product I can count on.
