If you're keen to discover one of the best retinol serums for your skin - look no further. From finding the best to showing you how to start using retinol - we’ve got you covered. Retinol has become a gold standard active ingredient, loved by beauty buffs, facialists, and aesthetic doctors alike but the skincare powerhouse has always been shrouded in a little mystery. 

Achieving its holy grail benefits of firmer, clearer, brighter skin is totally dependent on which formula you choose and how you introduce this skin perfecter into your routine. Found in Vitamin A, retinol is one of two derivatives available without a prescription. It's also the more potent out of the two and if you opt for an uber strong formula or use too much too soon the retinol uglies - dryness, irritation, acne and flaking - will no doubt ensue. 

We’ve rounded up and tested the best-selling retinol serums on the market and have been impressed by the skin sloughing, acne quelling, radiance imparting benefits of the Neostrata Retinol Repair Complex and the wrinkle busting prowess of potent Sunday Riley A+ High Dose Retinoid Serum.

When it comes to acne, exfoliation is key to stop pores clogging and spots erupting. Thankfully, this retinol serum has skin sloughing powers in spades. While 0.5% of pure, stabilized Retinol might not sound much since it’s possible to get higher dosages without a prescription, this seems to go above and beyond, speeding up cell turnover, boosting collagen and elastin production like a dream. Neostrata says this is thanks to the clever combination of retinol, amino acids, peptides, plant stem cells and neoglucosamine aka NAG. NAG, a precursor of much-loved hyaluronic acid, has many of the same benefits as retinol - blocking the formation of pigmentation, boosting cell turnover, collagen and elastin, as well as tightening pores and stopping acne in its tracks. And that is exactly what it does as long as you ease into this serum. Housed in a UV protected tube to stop the retinol from being broken down by UV rays and with a nifty pump to make it easy to dispense the pea-size amount needed - start slow to reap the long-term benefits. 

How to choose the best retinol serum for you

Make sure you do the research and follow dermatologist-approved tips before using. While a potent formula might sound like you’re getting your money's worth, retinol products can come in 0.3%, 0.5%, 1%, 1.5%, and 2% doses. If you’re new to retinol, it’s best to start low and work your way up - how low depends on your skin type. 

With that said the potency of most retinols on shelves ranges between 0.3 and 1 percent and these can work wonders to youth-boost your complexion. 

It's always recommended to check what additional ingredients your retinol serum may contain. While a moisturizing formula will be incredibly beneficial for dry skin, it could send acne-prone skin into overdrive.
