The Science behind our Serums

After no less than three years of meticulous formulating, I’m so excited to finally unveil our advanced new Serums.

What are serums? They are the most targeted, active and results-driven products in the range so far, and have been created as specific solutions for skin prone to redness and rosacea or acne.

I’ve put together a fool-proof guide with everything you need to know about them – read on for your Serum 101!

Lesson 1: Why should I use a Serum?

Serums perform a very different role to the other products in your skincare arsenal.

More liquid in consistency, they contain super concentrated actives carefully selected to target specific skin needs.These molecules are much smaller than those in a moisturiser – so the formula can penetrate the skin to a deeper level.

If you think of your day to day skincare regime like a good diet, then a Serum would be your super-charged dose of supplements – feeding skin any essential nutrients it may be lacking to restore it to its absolute best.

Lesson 2: How do I use a Serum?

Our Serums are best used at night on clean, dry skin as part of the following regime:

1. Cleanse with our Camellia & Rose Gentle Hydrating Cleanser.

2. Spritz clean skin with one of our BioAffinity Skin Tonics. I like to apply the Serum whilst my skin is still slightly moist from the Tonic, so the actives can absorb more effectively.

3. Warm one pump of Serum in your palm with clean fingertips.

4. Apply to the centre of the face working out with light pressing movements – no dragging the skin!

6. Leave skin to regenerate overnight. If you have particularly dry skin and feel you need extra hydration, follow with 1-2 pumps of your favourite Pai moisturiser.

Lesson 3: What are the active ingredients in our Serums?

As with all Pai products – the ingredients come first, and I’m so proud of the amazing breakthrough actives we’ve sourced for these super Serums.

Copaiba & Zinc Perfect Balance Blemish Serum

This blemish-busting treatment has been formulated to deliver the effectiveness of powerful acne products without any of the drying, sensitising or irritating side effects.

The Copaiba & Zinc Serum is based around a triple-action, anti-blemish complex of copaiba, acai and andiroba extracts, all sourced from the Amazon.

This trio work in synergy to deliver anti-bacterial, antioxidant and anti-inflammatory properties to treat both the causes and effects of blemishes.


Research found that after applying Copaiba complex daily for 8 weeks, testers observed*: 72% experienced fewer blemishes and 65% less sebum.


Zinc is brilliant for fighting blemishes, and our Zinc extract helps to reduce excess sebum production to cut down skin shine, blackheads and general congestion.

It also has great hydrating and collagen-boosting qualities, which when coupled with Hyaluronic Acid work in harmony to keep skin plump and hydrated.

Top tip: You can also use the Copaiba & Zinc Perfect Balance Blemish Serum as a targeted spot treatment; just apply to the affected area with a cotton bud and leave overnight.

Sea Aster & Wild Oat Instant Calm Redness Serum

The Sea Aster & Wild Oat Serum is the latest addition to our core Instant Calm range, specifically formulated for hyper-sensitive, redness and Rosacea prone skin.

I would say this Serum is the categories crowning glory – packed with skin soothing, redness reducing and hydrating botanicals; it’s the ultimate solution Serum for sensitive souls.

Redness is reduced by the amazing Sea Aster, which inhibits the release of cutaneous neuropeptides – the molecules that cause skin to flare, by 35%.

It also strengthens the surface blood vessel network, helping reduce the appearance of redness – particularly beneficial for Rosacea sufferers.

Sea Aster

Research found that after applying Sea Aster daily**:

  •  90% of people felt skin was less sensitive or reactive
  • 95% felt skin was more comfortable

Wild Oat

Sea Aster works alongside natural anti-histamine with anti-inflammatory, enriched Wild Oat which is well known for its skin soothing benefits and ability to improve the appearance of delicate or damaged skin.

Redness is instantly reduced and soothed, while ingredients including Hyaluronic Acid also work to improve long term skin health and suppleness.

Top Tip: You can apply our Sea Aster & Wild Oat Instant Calm Redness Serum not only on problem areas (e.g. Rosacea-prone cheeks) but to the entire face.
