Hyaluronic acid is one of the most biologically complex and nourishing molecules for the skin. It is found naturally in young skin, and decreases subsequently with age. It is responsible for retaining moisture within the skin, contributes to plumpness, softness, and firmness of skin tone. This oil-free, gel-like moisturizer is capable of holding 1,000 times its molecular weight in water. When applied topically, it forms a micro-viscous film that is gas permeable to allow for tissue respiration. It locks water into the skin, to prevent it from evaporation. Hyaluronic acid is also critical for proper cellular function & can drastically reduce the appearance of fine lines & wrinkles on the skin.
Our Mixed Molecular Weight Hyaluronic Acid Serum is made from the highest quality pharmaceutical grade sodium hyaluronate that ranges in molecular mass of between <6,000 and 1.5 million daltons (Da/u). We do not use the pre-made serum so widely available from other cosmetic websites on the Internet. We purchase the bio-engineered sodium hyaluronate in pure powder form & we make our own fresh solution in our lab. The sodium hyaluronate that we use is not derived from animal sources, but from the biofermentation of organic plant matter.

Great base layer for perfectly smooth makeup
This is the last thing I put on before makeup. My makeup glides on so smoothly. If I skip it in a rush, I can instantly tell the difference and my face seems drier.

HA
I love that this exists. This is an ingredient I used to chase in pricey skincare. Why pay for irritating fragrance? I either mix this with emu oil or use it as a layer under a moisturizer. Never stop making this, and can you please come out with a hydrolized pure HA serum?

Supplemental Moisture for dry weather/Stand alone moisture for humid weather
I love this product all year long for my combination skin. In winter I use it in conjunction with the PSF Moisture Balancing Lotion and my mineral sunscreen veil (not a PSF product but Skinceuticals). This combo really works for me in NYC. In summer, I use it with just the mineral veil sunscreen. The humidity plays in my favor keeping my skin comfortable and moist. If I've had a late night out or am under work deadline, I use a bit of this product under my eyes for a fresher look and feel. PSF HA is super well-priced and versatile. I won't be without it!

It's the bomb!
This is the moisture product for oily-break-out-prone folks. It's the bomb! And PSF makes it from a non-animal source, unlike a lot of other companies. GREAT product.
