Skin serums act as lightweight moisturizers that penetrate your skin deeper to distribute active ingredients more efficiently. They are quite potent and work especially well in combination with your daily moisturizer to give your skin the most powerful results.

Because serums are so potent, it only makes sense to have one in your skincare routine, but how do you use skin serum?

Skin serums should be applied twice each day in order to receive their maximum benefits. You’ll want to start your skincare routine by cleansing and toning your skin. Then, you will apply the serum of your choice and follow up with a moisturizer.

The important thing is to find a serum perfectly suited for your skin type!

If you have dry skin, you should check out our Aquasource Deep Serum. It is formulated with 35 nutrients to intensely hydrate your skin while still feeling incredibly lightweight! Our elixir gives you a luminous lit from within glow too, which you will love!

If you have dull skin, you will love our Aquasource Aura Concentrate! It works to provide your skin with up to 24 hours of intense regenerating hydration in just one application! It acts as a drink of water for thirsty skin and gives you a nice radiant looking glow!

If you have mature skin, you need to try our Blue Therapy Red Algae Uplift Cure serum. The formula contains red algae power to give you intense firming results! It is super lightweight and works to llift, firm, and tighten your skin. In just 28 days your skin will be completely transformed and look much younger, radiant, and smooth! Applying 6 drops of the serum onto your forehead, cheeks, chin, neck, and décolleté morning and night will give your skin a noticeable difference!

Another one those with mature skin will love is our Blue Therapy Accelerated Serum which works to help fight visible signs of aging and instantly softens your skin. It targets wrinkles, dark spots, and loss of firmness to give you dramatically improved skin over time!

Serums can seem intimidating, but they get applied just like a moisturizer would and offer even more results! If you’re looking to improve the quality of your skin, the serum is the best (and quickest) way to do so since they are so potent.
