Medik8 has unveiled its Black Friday sale, slashing 25% off everything on the website – great news for skincare aficionados looking to snag their favourite products for less. The sale is live now through to December 3 and also includes a free gift on orders over £120, which will come with a free Micellar Mousse worth £25.

This is an ideal chance to experiment with Medik8’s Crystal Retinal serum, a high-potency retinal concoction revered for its skin-smoothing, brightening, clarifying, and firming properties. Retinal is as much as 11 times more powerful than retinol, the more common type of vitamin A you’ll find in anti-ageing products.

Medik8 says it’s specially-crafted formula ensures its skincare range is stable, powerful and consistent. During the Black Friday sale, you can get your hands on a 30ml tube of Crystal Retinal strength 6 for £51.75, down from the usual £69.

Recognised as an effective nightly treatment against wrinkles, dark spots and blemishes, this cream comes in varying strengths to cater to different skin tolerance levels, reports the Mirror. It’s advisable to begin with a lower strength and gradually build up.

A particularly satisfied customer shared: “Love this product. I’m 66 years old and lived most of my life in the sun, we didn’t use sunscreen in my youth and I’m definitely showing signs of pigmentation. Since using Crystal Retinal and going up in strength, my skin has improved dramatically. I would recommend this and any Medik8 with a gold star rating.”

It’s important to remember that results may vary from person to person, as one Crystal Retinal customer said: “I wanted to like this but something in it is breaking me out. I feel like this is better suited for normal to dry skin.”

For those considering an alternative retinal product, Facetheory’s Retinal Supreme MultiCream 0.1% is available for £47 and has racked up numerous positive reviews. Medik8 is also offering a Black Friday deal on its C Tetra Luxe, now reduced to £44.25 for 30ml from the usual £59.

This Vitamin C serum is designed to boost skin’s natural glow with its antioxidant properties and deep hydration. A satisfied shopper said: “I was advised to [use] Medik8 after a facial using these products. I can’t recommend them enough. I have seen a vast improvement in my skin pigmentation issues.”

However, another added: “I’ve already used one bottle of C-Tetra Luxe but haven’t seen much difference to be honest. But I’ve repurchased it as I’ve already tried two other brands before and this one feels better than those on my face.”

To combat the drying effects of winter weather, shoppers can also find savings on Medik8’s Hydr8 B5 Intense, currently priced at £44.25 down from £59. This hyaluronic acid-based treatment is a powerful moisturising serum that provides long-lasting and rapid effects.

It’s described as soft and non-sticky, maintaining the plumping and firming benefits associated with Medik8 products. A review reads: “I love this product. Makes my skin so smooth, soft and hydrated. I love to use under makeup and it makes my skin look shiny. I got a lot of compliments.”

However, as with all cosmetic products, individual results may vary, with another shopper noting: “The feel of this serum is lovely but it doesn’t seem to do that much for me.”
