SkinCeuticals Hyaluronic Acid Intensifier
Updated: Jul 19
SkinCeuticals Hyaluronic Acid Intensifier ($100, 1 oz) is a multi-functional corrective serum that helps to amplify skin’s hyaluronic acid levels. Hyaluronic acid is a naturally occurring substance in the body that helps skin and joints retain moisture and it also prevents moisture from evaporating into the air. Unfortunately, your body’s levels of hyaluronic acid decreases with age and so it is used in skincare products to act as a magnet for moisture so that your skin appears hydrated, plump and healthy. SkinCeuticals H.A. Intensifier is used to address the following skincare concerns: dryness, aging, sun damage, loss of firmness and fine lines and wrinkles. It is ideal for all skin types; dry, normal, oily, acne-prone, combination, sensitive or mature skin.
About the Brand
SkinCeuticals is a high-end skincare line founded by Dr. Sheldon R. Pinnell, a Professor Emeritus of Dermatology and the former Chief of Dermatology at Duke University Medical Center. SkinCeuticals products are based on cutting edge research and innovation, establishing the brand as a leader in advanced skincare. Although SkinCeuticals is most widely known for its patented antioxidant serums, products such as the H.A.

If you are the using H.A. Intensifier in the morning, apply it after your vitamin C serum and before sunscreen. But, if are using the H.A. Intensifier with a retinol at night, apply the H.A.

After doing a little research, I learnt that the problem with most products that contain hyaluronic acid is that they are unable to deliver the hyaluronic acid deep into the skin’s layers, where it is most needed, because the hyaluronic acid molecule is too large to effectively penetrate the skin’s layers and deliver hydration. Instead, the hyaluronic acid in those products just end up sitting on the surface of the skin and are not delivering the hydration that your skin needs. In an interview with Harper’s Bazaar, Dr. Rachel Nazarian, a NYC-based dermatologist, said that the key to a good product with hyaluronic acid is if the product either micronizes the hyaluronic acid molecule so that it can penetrate the skin or if it puts the hyaluronic acid in a vehicle that penetrates the skin in order to be effective where it needs to be. SkinCeuticals H.A. Intensifier does the latter, by uniquely combining surface-hydrating hyaluronic acid with 10% proxylane and a concentration of licorice and purple rice extracts to support skin’s hyaluronic acid levels. So, after learning about the benefits of hyaluronic acid and the science behind SkinCeuticals H.A. Intensifier, it was the hands down choice to include in my skincare regimen.
The H.A. Intensifier comes in a dark purple glass bottle and it is a light purplish liquid formulation. It is not scented but it is a thick liquid that feels a little heavy but not sticky on the face. I apply the H.A. Intensifier only at night (primarily because of the price and I want to make it last as long as possible), after I cleanse my face and apply toner and retinol. To apply, I put 4 drops in the palm of my hand and dab it onto my face as shown in the SkinCeuticals video linked to above. Whenever I use the H.A. Intensifier, my face feels more moisturized the following day, which is a big deal in the extremely dry air here in Utah. Also, I have noticed that whenever I use the hyaluronic acid, my face is less oily the following day because my face is not producing more oil to compensate for the dry air.
Although I sometimes use the H.A. Intensifier without my retinol, hyaluronic acid pairs well with most other skincare ingredients and products such as peels, retinols and other acids. According to Dr. Nazarian, the only exception to this general rule is acids with low pH levels, like glycolic acid, because it may degrade the hyaluronic acid and make it ineffective. Additionally, because hyaluronic acid is such a powerful humectant, you do not need more than one product with hyaluronic acid in your skincare routine.
I highly recommend SkinCeuticals H.A. Intensifier and join the chorus of other people worldwide who love this product. The one downside of this product is its price, so once I finish my current bottle, I will be looking for less expensive alternatives and I will be sure to post my review(s) when I do!
