For skin showing fine lines and deeper wrinkles, a potent antioxidant from the sea.

Winner of Best Deep Wrinkle Serum in the 2024 Earth Day Beauty Awards. Finalist for Best Face Serum in the 2024 Clean Beauty Awards.

Seaweed and Me Youth Serum is a marine botanical serum from Rosemira, made to smooth the look of fine lines and wrinkles and support a firmer, more even-toned complexion. It is hand batched fresh without synthetic preservatives, so the actives are still potent when they reach your skin.

Why it works

Astaxanthin from red algae is one of nature's most powerful antioxidants. Paired with argan and buriti oils and a blend of nourishing essential oils, it helps defend the look of skin against everyday environmental stress, supports elasticity and moisture, and softens the appearance of fine lines, wrinkles, and uneven tone over time.

Key botanicals

• Astaxanthin red algae: a powerful antioxidant that supports a smoother, more even look
• Moroccan argan oil: antioxidant rich and revitalizing, naturally high in vitamin C
• Brazilian buriti oil: moisturizing and nourishing
• Blue malva flower: softening and soothing

Choose your version

The Original Astaxanthin Serum is granular, because seaweed is naturally gelatinous. A few small metal balls are included to help disperse the granules when you shake it. Some people enjoy the granular texture and use it as a gentle exfoliant, massaging it in and flicking off the remaining granules. If you prefer a smooth serum, choose the CO2 Extract version, which uses a supercritical extraction of seaweed for a smooth, very potent feel.

How to use

Use after cleansing and toning. Shake well, then massage a few drops onto damp skin, focusing on areas of concern, and take care to avoid the eyes. It works well as a day serum, though it is not a sunscreen and is not a substitute for one.

Who it is for

All skin types, including dry, mature, and sensitive skin, and anyone wanting to soften the look of fine lines, wrinkles, and uneven tone.

The Rosemira difference

Every Rosemira formula is hand batched fresh and made without synthetic preservatives, because fresh botanical actives work and most skincare is already too old to prove it. Each formula is rooted in founder Dr. Mira Herman's forty years of clinical practice as a herbalist, acupuncturist, chiropractor, and nutritionist.
