The only Amazon Prime Day beauty deals I'd spend money on, as a beauty editor of 12 years

Having been a beauty journalist for well over a decade now, I've seen countless shopping events, Black Friday sales and Amazon Prime Weeks come and go, and sometimes I do think the deals are just a bit weak. After all, a quick search of the internet will almost certainly bring you up at least one other e-tailer who will sell you the exact same product for even cheaper on any given day,

Saying that, I do still find some deals that can't be beaten during Amazon Prime Weeks, it just takes a fair bit of looking. To save you from doing that, I've done the hard work for you by finding the very best deals from trending and top brands, ranging from Medik8 to Redken.

Even better, I can guarantee you won't find better prices for them elsewhere (from all the reputable places, anyway)...

Isle of Paradise Self Tanning Face Drops Medium Was £19.95 now £8.99

Just add a few drops to your moisturiser or serum, and voilà—your skin will gradually develop a gorgeous, even tan. The colour is buildable, so you can go as light or as dark as you like, with no streaks or orange tones. I like this one because it doesn't cause breakouts, like many of the other face tans do.

Wonderskin Wonder Blading Lip Stain Peel Off Masque Was £18 now from £13

This transfer-proof, waterproof lip stain gives your lips a bold, smudge-free pop of colour that stays put all day. It feels lightweight and comfortable, so you can go about your day without worrying about touch-ups. I wore the Charming shade to a wedding last week and it didn't budge for 6 hours.

Kérastase Genesis Hair Serum Was £49.50 now £32.90

This lightweight serum helps reduce hair fall due to breakage, leaving strands feeling stronger, smoother and healthier. With regular use, it helps promote thicker-looking hair, all while soothing your scalp – and I can attest to that.

COSRX Advanced Snail 92 All-in-One Cream Was £23.99 now £11.80

Packed with 92% snail mucin, it helps to repair, nourish, and lock in moisture without feeling heavy. Perfect for dry or tired skin, it leaves your face feeling soft, smooth and looking refreshed. You just need to get your head past the snail thing.

Eylure Dybrow Permanent Tint for Brows Was £8 now £5.50

This easy-to-use tint gives your brows a natural, long-lasting colour that stays put for weeks. I've been using this instead of going for brow tint appointments at salons for years now and I've saved so much money. Plus, my brows always look great, if I do say so myself.

Medik8 C-Tetra - Lipid 7% Vitamin C Radiance Serum Was £42 now £33.60

Packed with stable Vitamin C, it helps reduce signs of ageing while giving your skin a radiant, even glow. Its lightweight, nourishing formula absorbs easily, leaving your skin looking fresh, smooth and more youthful. I've got my mum hooked on this, too.

Tangle Teezer Ultimate Detangler Hairbrush Was £15 now £9.97

This is the only brush I'll use on my knot-prone hair. It gently glides through knots and tangles, leaving your hair feeling soft and manageable without any pulling or breakage. Perfect for all hair types, this little beauty is ideal for detangling both wet and dry hair.

Redken All Soft Shampoo and Conditioner Set Was £47.30 now £35.91

I always say that there's no point in investing in expensive colour appointments if you're going to wash it straight down the drain with cheap shampoo. This duo is infused with argan oil to gently cleanse and nourish, leaving your locks feeling super soft, smooth and manageable. Perfect for dry or brittle hair, it helps restore moisture and gives your hair a healthy, silky finish.

Nizoral Anti-Dandruff Treatment Shampoo Was £13.99 now £9.69

I use this once a week to keep dandruff at bay, and also because I read that it contains an ingredient that reduces the production of DHT (a hormone linked to hair loss). SInce I've been using it, my scalp hasn't been itchy at all and my hair does indeed look a little thicker.
