The Hyaluronic Acid Boosting Serum has a smoothing blend of ingredients that provide deep, long-lasting hydration on three levels: on the surface, deeper in the skin and by increasing the skin’s own hyaluronic acid production.

Hydrolyzed hyaluronic acid in the Hyaluronic Acid Boosting Serum penetrates deeper into the skin, attracting and holding moisture that’s already in the skin, and plumps fine lines from below the skins surface, whereas the HA-Pro Complex™ is a proprietary blend that stimulates the production of the skin’s own hyaluronic acid and delivers 24-hour hydration. It leads to long-term hydration and anti-aging.

The product also contains Ceramides which supports the renewal of the skin’s natural protective layer and forms an effective barrier against moisture loss. The Hyaluronic Acid Boosting Serum also has Niacinamide, a potent, yet calming antioxidant that reduces moisture loss in the skin and improves barrier function. It also reduces redness and promotes an even skin tone.

✓ Triple-Action Hyaluronic Hydration | ✓ 55% More Hydration After One Use | ✓ Suitable for All Skin Types

PCA Skin Hyaluronic Acid Boosting Serum is PCA Skin's best-selling hero serum and its answer to thirsty, tired-looking skin: a triple-action hydrator that works on the surface, deeper in the skin and over time by supporting your skin's own hyaluronic acid. Suitable for all skin types, it is the hyaluronic acid serum for plumper, smoother, more supple-looking skin morning and night.

Hyaluronic acid and sodium hyaluronate hold up to 1,000 times their weight in water for instant surface smoothing, while smaller-molecule hydrolysed hyaluronic acid delivers deeper hydration that plumps the look of fine lines. PCA Skin's proprietary HA-Pro Complex supports the skin's natural hyaluronic acid levels for 24-hour hydration, and ceramides and niacinamide reinforce the moisture barrier and calm the look of redness. PCA Skin cites in vitro data showing PCA Skin Hyaluronic Acid Boosting Serum amplifies the skin's hyaluronic acid levels by 50% within 24 hours, and it was clinically shown to increase overall skin hydration by 55%, improve plumpness by 60% and improve the look of fine lines by 31% (corneometer measurement after one use, supported by a six-week clinical study of 40 people).

FAQS

Is PCA Skin Hyaluronic Acid Boosting Serum good for dry, dehydrated skin? +

Yes - dry and dehydrated skin are first on PCA Skin's list. In the brand's testing it increased overall skin hydration by 55% after one use, with ceramides and niacinamide helping the skin hold on to that moisture.

Can I use PCA Skin Hyaluronic Acid Boosting Serum with retinol or vitamin C? +

Yes. PCA Skin lists no products it should not be used with. Apply it straight after cleansing, then layer vitamin C in the morning or retinol in the evening according to their own directions.

What does triple-action hydration mean? +

The serum hydrates in three ways: hyaluronic acid and sodium hyaluronate smooth and hydrate the surface instantly, hydrolysed hyaluronic acid reaches deeper to plump the look of fine lines, and HA-Pro Complex supports your skin's own hyaluronic acid for longer-term hydration.

What is HA-Pro Complex? +

It is PCA Skin's proprietary blend that supports the skin's natural hyaluronic acid levels to help improve the appearance of smoothness and plumpness, delivering 24-hour hydration.

What did PCA Skin's testing show? +

PCA Skin reports a 55% increase in overall skin hydration, a 60% improvement in plumpness and a 31% improvement in the look of fine lines, based on an immediate corneometer measurement after one use and supported by a six-week clinical study of 40 people. Separate in vitro data showed a 50% boost in hyaluronic acid levels within 24 hours.

Is it suitable for oily or sensitive skin? +

Yes. PCA Skin describes it as suitable for all skin types and lists it among its products for sensitive skin. Patch test first if your skin is reactive.

When should I apply it in my routine? +

Morning and evening, straight after cleansing, to the entire face and neck. Follow with your other serums, then a broad-spectrum SPF in the morning or your moisturiser at night.

Does it contain fragrance? +

Yes, a light one. The UK ingredient list includes parfum along with limonene and linalool, so if your skin is sensitive to fragrance, patch test before first use.

Can I use PCA Skin Hyaluronic Acid Boosting Serum during pregnancy or while breastfeeding? +

It contains no vitamin A, the ingredient group most often advised against at this time, and hydrating ingredients such as hyaluronic acid are generally considered suitable during pregnancy and breastfeeding. PCA Skin does not publish specific pregnancy or breastfeeding guidance for this product, so please show the full ingredient list to your midwife or GP and check with them before use.
