Building the foundations for better-looking skin, the BIOEFFECT EGF Serum helps to plump, hydrate and smooth the appearance of skin for a visibly revived complexion. Enriched with the brand's signature Epidermal Growth Factor (or EGF), the formula is powered by an advanced protein that encourages a firmer look. The serum also locks in moisture to nourish the skin for long-lasting hydration. This minimalist formula promotes powerful results.
