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.

✓ 3 Types of Hyaluronic Acid | ✓ 50% More Hydration in 24 Hours | ✓ Suitable for All Skin Types

PCA Skin Hyaluronic Acid Boosting Serum delivers intelligent, multi-level hydration that goes far beyond what a standard hyaluronic acid serum can offer. Formulated with three different forms of hyaluronic acid, this award-winning serum works on the skin's surface, deep within the dermis, and at cellular level to help amplify your skin's own HA levels by 50% within 24 hours. The result is visibly plumper, smoother, and more youthful-looking skin from the very first application.

Powered by the proprietary HA-Pro Complex™, this lightweight serum doesn't just add moisture — it encourages your skin to produce its own hyaluronic acid for lasting hydration and anti-ageing benefits. Protective ceramides strengthen the skin barrier to lock moisture in, whilst niacinamide calms redness and promotes a more even complexion. In clinical studies, users experienced a 55% increase in skin hydration, 60% improvement in plumping, and a 31% reduction in fine lines after just six weeks. If you've been searching for the best hyaluronic acid serum for dehydrated or ageing skin, this is it.

FAQS

Is PCA Skin Hyaluronic Acid Boosting Serum safe to use during pregnancy and breastfeeding? +

This serum does not contain retinoids, salicylic acid, hydroquinone, or other ingredients commonly advised against during pregnancy. The formula is based around hyaluronic acid, ceramides, and niacinamide, which are generally considered safe for use during pregnancy and breastfeeding. However, we always recommend consulting your GP, midwife, or dermatologist before making any changes to your skincare routine during pregnancy or whilst breastfeeding.

How long does one bottle last? +

The 30ml bottle typically lasts between 6 to 8 weeks with twice-daily use, as only one pump per application is needed to cover the entire face and neck. The airless pump dispenser ensures you get the right amount each time and helps keep the formula fresh and effective right down to the last drop.

Will this serum cause pilling under my makeup? +

When used correctly, this serum should not cause pilling. Apply one pump to clean skin and allow it to fully absorb before layering additional products or makeup. Many users find it actually improves makeup application by creating a smoother, more hydrated base. If you do experience any pilling, try using a slightly smaller amount or waiting a little longer between layers.

Can I layer this serum with other products like vitamin C or retinol? +

Yes, this serum layers beautifully with other active treatments. In the morning, apply after your vitamin C serum and before your SPF moisturiser. In the evening, it works well alongside retinol products — apply the hyaluronic acid serum first to provide a hydrating base, then follow with your retinol treatment and moisturiser. Allow each layer to absorb before applying the next for the best results.

Does PCA Skin Hyaluronic Acid Boosting Serum help with fine lines and wrinkles? +

Yes. The hydrolysed hyaluronic acid in this serum penetrates deeper into the skin to plump fine lines from below the surface. In a six-week clinical study, participants experienced a 31% improvement in the appearance of fine lines. The deep hydration helps skin appear firmer and smoother, reducing the visibility of lines caused by dehydration and ageing.

How quickly will I see results? +

You'll notice an immediate boost in hydration and skin smoothness from the very first application. The serum helps amplify the skin's hyaluronic acid levels by 50% within 24 hours. For more significant improvements in fine lines, plumpness, and overall skin texture, clinical studies showed measurable results after six weeks of consistent twice-daily use.

Can I use this serum if I have oily or sensitive skin? +

Absolutely. This serum is suitable for all skin types including oily, combination, normal, and sensitive skin. The lightweight, non-greasy formula absorbs quickly without clogging pores or leaving a heavy residue. The niacinamide in the formula is particularly beneficial for sensitive skin as it helps calm redness and improve barrier function without causing irritation.

Is this the best hyaluronic acid serum for dry, dehydrated skin? +

This serum is specifically designed for deep, lasting hydration and is an excellent choice for dry or dehydrated skin. Clinical studies showed a 55% increase in overall skin hydration and a 60% improvement in skin plumping after six weeks of use. The added ceramides help strengthen the moisture barrier to prevent future water loss, making it particularly effective for skin that struggles to retain hydration.

What makes PCA Skin Hyaluronic Acid Boosting Serum different from other HA serums? +

Unlike most hyaluronic acid serums that only hydrate the skin's surface, this serum works at three distinct levels. Standard-weight hyaluronic acid smooths and hydrates on top, hydrolysed hyaluronic acid penetrates deeper to plump fine lines from within, and the proprietary HA-Pro Complex™ actually stimulates your skin to produce more of its own hyaluronic acid. This triple-action approach delivers both immediate and long-term hydration that most single-form HA serums simply can't match.
