If you’re in your 20s or early 30s, chances are aging isn’t top of mind just yet. Still, there are a few simple things you can start doing now to keep your skin looking healthy longer. When it comes to future-proofing your complexion, consistency is key: protect skin in the morning and help renew it at night. Ahead, the four clean, clinically tested, seaweed-powered essentials we swear by for youthful-looking skin today and over time.
What Are Signs of Premature Aging?
Tell-tale signs can include the early onset of fine lines and wrinkles, hyperpigmentation and dry skin. But what actually causes premature aging? Sun damage, pollution and environmental stressors can create free radicals in the skin. The result? Dullness, dryness, uneven tone, wrinkles and loss of firmness and elasticity. All are normal parts of aging — but if you’re noticing them sooner than expected, you might be experiencing premature aging.
Daytime Routine
Whether you’re new to anti-aging skincare (welcome!), or want to get your skin back on track once and for all, a daily morning skincare routine is the very best place to start. The aim of the game? Hydrate, moisturize and protect skin for the day ahead.
Step 1: Moisturize
All skin needs moisturizing, whether it’s dry, dehydrated, reactive or oily. The key is to find the right combination of ingredients that work for you. After cleansing, you’ll want to smooth on a moisturizer to your entire face. Reach for a lightweight, fast-absorbing formula that hydrates without clogging your pores.
Our Atmosphere® Protection Cream is a featherweight, everyday moisturizer clinically shown to counteract the visible signs of aging from pollution and preserve skin’s youthful appearance. Powerful elfdock (a plant hailing from the sunflower family) combines with Undaria seaweed to visibly reduce damage caused by environmental stressors while improving skin elasticity. Our formula also uses niacinamide to boost hydration and enhance the skin’s barrier along with shea butter to revive dry skin, leaving it soft, smooth and deeply moisturized. And the scent itself is absolutely addictive—subtle rose geranium, clary sage and soothing chamomile.
Step 2: Protect With SPF
Your future skin will thank you. Sunscreen is one of the best, and easiest, ways to protect your skin’s appearance at any age. UV damage happens year-round. Through windows, even on cloudy days. That’s why SPF matters 365 days a year. It’s the essential last step in your daily routine. The trick is finding one you actually want to wear. You need something that protects, primes for makeup and layers nicely over everything else in your routine.
Enter Marine Screen SPF 50—a daily mineral sunscreen designed for the sun you live in. This lightweight, fragrance-free formula delivers broad-spectrum protection to help prevent visible signs of aging while nourishing skin. Non-nano zinc oxide, a clean, eco-friendly mineral filter, shields against both UVA and UVB rays, while nutrient-rich seaweed and hyaluronic acid hydrate skin. Blendable, non-greasy and untinted, it wears beautifully on its own, over moisturizer, or under makeup. Apply at least 15 minutes before sun exposure and reapply every two hours for full SPF protection. Marine Screen is suitable for all skin types and safe for sensitive skin. It's not just sunscreen for the beach; it's a defense for everyday living.
Nighttime Routine
If you’ve started (or are considering) a nighttime anti-aging skincare routine, you’ve likely heard of retinol – the gold standard in anti-aging skincare. You might also know that retinol can be a little harsh on the skin, so it’s not exactly for everyone. Luckily, there is a plant-based alternative, bio-retinol, that mimics the effects of traditional retinol but without the associated irritation. Here’s how to incorporate this powerhouse ingredient into your nighttime skincare routine for youthful-looking skin, now and for decades to come.
Step 1: Treat
Meet Dream Night Serum with Bio-Retinol, our most advanced anti-aging formula yet. This powerful treatment works overnight to visibly reduce crow’s feet, fine lines, wrinkles, and even deep wrinkles—at every age and stage of life. Whether you’re in your 20s and starting to see the first signs of aging or in your 60s and beyond, experiencing deeper creases and loss of firmness, this serum is designed to support your skin’s needs over time. Powered by algae-derived bio-retinol and two firming peptides, it’s clinically shown to visibly improve skin firmness after 4 weeks*. Wake up to smoother, more youthful-looking skin.

Step 2: Moisturize
Sleep gives our skin the chance to renew, leaving it softer, smoother and rejuvenated. And the right night cream can play a big role in that. Not only will it seal in the goodness of your serum, but the best one will help you wake up looking rested, refreshed and radiant by morning. Like the other products in our Dream Collection, our Dream Night Cream with Bio-Retinol visibly firms and smooths fine lines and wrinkles. And it goes one step further. Inspired by psychodermatology, a field that explores the link between the mind and skin, this innovative formula is the first night cream clinically shown to reduce the visible effects of stress on skin*. In clinical testing, Dream Night Cream was also shown to visibly firm skin and visibly reduce dark circles in just two weeks*. Give it a few weeks to work its magic, and we promise you’ll never go without it again.
