Product Insights & Style Tips

Kate Somerville® +Retinol Vita C Power Serum Firming + Brightening Treatment delivers a spa-fresh glow in a bottle. It stabilizes vitamin C and retinol for brightening, firming, and evening skin tone, while neutralizing free radicals that drive aging. In an independent study on 30 people after one use, 100% showed highly significant improvement in pore size and 97% in fine lines and wrinkles. After one week, 94% showed improvement in fine lines, 93% in skin elasticity, 90% said their skin tone looked brighter, 96% felt it was softer, and 90% noted smoother, more luminous skin. After 10 days, 94% showed improvement in fine lines, 93% saw firmer skin, and 90% reported brighter, more radiant and more luminous complexions.

Use the serum daily at night. After cleansing, apply a thin, even layer to face and neck, avoiding the eye area. The 1 oz formula is paraben-free, sulfate-free, and phthalate-free, and is made in the USA, offering a clean, prestige touch to a nightly routine.

Kate Somerville is known for clinical-grade skincare that reads like a spa ritual, and this +Retinol Vita C Power Serum embodies that ethos with a streamlined, high-impact approach to brightening and firming.

Beauty Trends & Makeup Tips

Your Fall Mani Inspiration Is Here

Fall nail season is officially here, and after some extensive research, one thing is clear: rich, earthy shades are taking over. The palette feels like a natural extension of the season itself – moody and deeply satisfying in the way that only autumn color can be. These fall nail colors are for the girl who fully commits to the seasonal switch. The one who darkens her hair, trades pastels for deeper hues, and embraces autumn the moment September hits without looking back. Your nails deserve the same treatment. Whether you’re a DIY regular or bringing inspo straight to your nail tech, these are the shades worth adding to your fall mani list right now.

The Sultry 90s Updo Is Back In Style

If you thought the 90s revival had already given us every possible throwback, there’s another classic making its way back into the rotation. The 90s updo is back, and it’s bringing plenty of volume with it. After years of sleek, slicked-back buns dominating the beauty scene, the mood is shifting toward something softer, fuller, and a little more nostalgic. The shape still feels polished, but the added height and undone texture give it a sexier edge. It’s also surprisingly versatile. Wear it loosely for a coffee run or style it with more definition for a night out. Ahead, the tips and products you need to recreate the 90s updo and keep every strand in place.

Transition Into Fall With Plum Makeup

Some things are classics for a reason, and that’s exactly how we feel about plum makeup come autumn. Much like pulling out your coziest sweater, this deep berry shade just makes sense. Its rich, slightly brown undertone adds a distinctive cold weather vibe to your everyday beauty routine without feeling overly dramatic. It also pairs beautifully with warm, healthy-looking skin, making it the perfect transition shade from summer to fall. While you can go all in with a burgundy-inspired makeup look from cheeks to lips, you can also take a more understated approach by choosing just one or two features to highlight. Ahead, we’re sharing a couple of our favorite ways to wear plum makeup effortlessly this season.
