Algae, the plant-like organisms that grow in water, may not seem like an obvious skincare ingredient. However, algae extract offers many benefits for skin health and appearance. Extracts from different algae varieties can moisturize, protect against pollution, even out skin tone, and provide antioxidant protection.
Why Algae is Good for Skin
Algae contain bioactive compounds that provide significant skincare benefits when applied topically or taken orally as a supplement. These include:
- Antioxidants like carotenoids, polyphenols, zinc, selenium, vitamin E, and vitamin C neutralize skin-damaging free radicals.
- Amino acids like glycine, lysine, and arginine build collagen and elastin.
- Vitamins and minerals like iron, calcium, magnesium, potassium, and B vitamins nourish skin cells.
- Anti-inflammatory compounds like fucoidan and polyphenols that calm irritation.
- Moisturizing agents like algin, carrageenan, and agar help skin retain hydration.
Different Types of Algae and Their Benefits
There are thousands of algae species, but some commonly used in skincare include:
Green Algae
Chlorella and other green algae deliver proteins, vitamins, minerals, and the antioxidant lutein to nourish, protect, and hydrate skin.
Red Algae
Dulse is rich in minerals like iron, magnesium, and zinc for healthy skin cell metabolism. It also contains fucoidan to reduce inflammation.
Brown Algae
Kelp contains algin, fucoidan, and laminaria saccharine to hydrate skin and smooth the appearance of fine lines.
Ascophyllum nodosum has antioxidant phenolic compounds that protect against UV damage and pollution.
Blue-Green Algae
Spirulina provides carotenoids, proteins, and vitamins C, E, and B to combat aging. It also has anti-inflammatory gamma-linolenic acid (GLA).
Top 5 Evidence-Based Benefits of Algae for Skin
Here are some of the top ways that research shows algae can improve skin appearance and health:
1. Hydration
Algae contain polysaccharides that help skin attract and retain moisture. A study in the International Journal of Biological Macromolecules found that adding 5% algae polysaccharides to skin creams improved hydration by 70% compared to placebo creams.
2. Smoothing Fine Lines and Wrinkles
Applying creams with red and brown algae extracts can significantly reduce the depth of wrinkles. One study in Clinical, Cosmetic, and Investigational Dermatology showed combining algae with retinol led to 44% smoother skin.
3. Protection from Pollution
Algae is rich in antioxidants that neutralize the free radicals from skin-damaging pollution and blue light from screens. A study in Marine Drugs showed algae extracts protected skin cells from up to 95% of pollution-induced cell damage.
4. Soothing Sensitive and Irritated Skin
Algae’s anti-inflammatory compounds like fucoidan calm redness and sensitivity. In a study in Esthetic Dentistry & Cosmetic Dermatology, an algae-based moisturizer reduced symptoms of eczema, including itching and flaking, by up to 20% more compared to standard care.
5. Evening Skin Tone
The antioxidants in algae, especially astaxanthin, can reduce uneven pigmentation and age spots. A 12-week study found daily oral supplements with algae led to significant improvements in age spots and brighter, more even skin tone.
How to Use Algae on Your Skin
Here are some easy ways to incorporate algae into your skincare routine:
- Look for moisturizers, serums, masks, cleansers, and sunscreens that contain algae extracts, especially brown and red algae.
- Use an algae sheet mask 1-2 times per week for an intense hydration boost.
- Apply an algae-infused cream before bed to wake up with smoother, plumper skin.
- Take an astaxanthin or spirulina supplement for antioxidant protection against pollution and UV damage.
- Use skincare products that combine algae with other anti-aging ingredients like retinol, vitamin C, hyaluronic acid, and niacinamide.
The Takeaway
With their stellar nutrient profile and clinically proven benefits, marine algae should be a staple ingredient in every anti-aging skincare routine. Harness the power of the sea to reveal hydrated, smooth, even-toned, and luminous skin. When sourced ethically and sustainably, algae is one of the ocean’s best-kept secrets for youthful, healthy skin at any age.

Brown algae like kelp and red algae like dulse contain beneficial compounds for the skin like fucoidan, carotenoids, and algin. Blue-green algae like spirulina also provide antioxidants.
Is algae cream good for your face?
Yes, creams containing algae extracts absorb well and provide hydration and antioxidant protection. Look for formulas with red, brown, or blue-green algae.
Can you use algae directly on your skin?
It’s best to use algae extracts in skincare products formulated for facial skin rather than applying raw algae. Algae skincare products provide the right concentrations and combinations.
