Marine algae are rich in:

Benefits For Your Skin

When you forget that you’re applying algae on your face is when you truly realize the benefits it offers you. Practically an all-in-one substance to tackle all your skin problems.

Bioseaweed primarily acts by inhibiting enzymes that accelerate the aging of the skin. Complex carbohydrates present in microalgae provide a boost of moisturization to the skin and also helps in repairing the damaged skin barrier.

Aqueous extracts from Red and Brown Algae can reduce hyperpigmentation by reducing the melanin synthesis of the skin. They work wonders in fading away acne scars and also prevent breakouts. 

Red algae extracts are very hydrating and soothe sensitive skin. The extracts of red algae contain a mild form of vitamin A, which can act as Bio-Retinol without the usual side effects.

4. Marine Algae vs. Retinol

Bio-Retinols like Bio Seaweed and Bakuchiol have not undergone thorough research and experiment. However, seaweeds have been found to have bioactive compounds that stimulate the production of certain age-reversing molecules in the skin. 

Bio Seaweed extracts prevent cell death and aging. It does not cause any dryness or irritation unlike retinol and will suit many different skin types.
