Before and after results

Protocol: A 12-week, single-center, clinical study was conducted on 59 females, ages 42-60, with mild to moderate facial sagging and loss of firmness, rough skin texture, nasolabial fold wrinkles, marionette wrinkles, and presence of fine lines/wrinkles in the crow’s feet area. H.A. Intensifier was used twice daily in conjunction with Gentle Cleanser and a sunscreen. Efficacy and tolerability evaluations were conducted at baseline and at weeks 4, 8, and 12.

Rated 5 out of 5 by from Moisture boost I love this product. I find it’s wonderful on sensitive skin. I also recently had a sensi face peel and i used this with my C e Ferulic and they both really helped by skin as a duo. I also used H.A intensifier after my evening cleanse and it helped my skin heel so much faster. I wouldn’t be without it

Rated 5 out of 5 by from Ultimate hydration This serum made my skin softer and smoother, and now it looks plumper and healthier. I apply it twice a day and my sensitive skin is really grateful. It's safe for all skin types and can be used to improve the appearance of crow's feet and the nasolabial folds—making it especially good for someone looking for help with skin aging. It has an immediate hydrating effect. I apply it after cleansing and prior to moisturizing, as HA is especially beneficial to apply it while the skin is still damp (this helps draw the moisture further into the skin). Highly recommend it.
