Key ingredients

  • Stabilised Vitamin C

    Our all-natural Vitamin C is sourced from corn and coconut. It’s oil-soluble and stabilised to ensure it’s slow-releasing, delivering radiant results right down to the last drop.

  • Hyaluronic Acid

    A sugar the body naturally produces, Hyaluronic Acid can hold between 10 and 50 times its weight in water, storing it like a reservoir for the skin – giving a long-lasting, moisturising effect. Our all-natural form comes from maize.

  • Peptides

    Peptides are clever amino acids best known for stimulating collagen and elastin - meaning fewer lines and firmer skin. Ours is all-natural: yeast-derived Hexapeptide joins the humble yet hardworking Pea Peptide, rich in lysine to support healthy skin.

How to Use

Use these versatile boosters whenever your skin needs them, morning or night.

Add 1-2 drops into your skincare (moisturisers, serums, or even body products). Alternatively, use neat, applying 1-2 drops directly onto dry cleansed skin, then follow with the rest of your routine.

We recommend dropping Vitamin C into your morning routine for protection throughout the day, but you do you.

Recycling

We do our bit so it’s easy for you to do yours. Check out our instructions on how to recycle Pai packaging.

Sarah Brown, Pai Founder

"Most people think actives and sensitive skin are a trade-off. We built these boosters to prove they're not. Hyaluronic acid, vitamin C, peptides — three of the most evidence-backed ingredients in skincare, in one kit, at concentrations that actually work. Made by us. Mixed by you."

SARAH BROWN
FOUNDER, PAI SKINCARE

Frequently Asked Questions

How do the boosters in this kit actually work?

Each booster is a concentrated single-active serum. You add 1–2 drops into your existing moisturiser, mix in your palm, and apply as normal. No new steps, no routine overhaul. You can use one at a time or combine all three in the same application.

Can I mix these boosters with any moisturiser, or only Pai moisturisers?

You can mix them into any moisturiser you already use. The booster format is designed so the active is delivered through your moisturiser's base, so there's no need to switch products. That said, Pai's Chamomile & Rosehip Calming Day Cream is a particularly good match if you're looking for a sensitive-skin-friendly base.

When should I use each booster in my routine?

Vitamin C works best in the morning for daytime antioxidant protection. Hyaluronic Acid suits both morning and evening. Peptides can be used morning and evening, or evenings only, and it's also suitable around the eye area.

Is this kit suitable for sensitive skin?

Yes. All three boosters are fragrance-free, essential oil-free, and have undergone 96-hour human repeat insult patch testing, which goes beyond standard industry requirements. The Vitamin C is oil-soluble, so it causes none of the pH-related irritation that water-soluble vitamin C at high concentrations is known for.

Can I use these boosters during pregnancy or breastfeeding?

Yes. All three boosters in the kit are confirmed safe for use during pregnancy and breastfeeding. They contain no retinoids, no essential oils, and no ingredients flagged for concern during this period.

How do the three boosters work together for ageing skin?

Pai's lead chemist recommends Peptides paired with Hyaluronic Acid as the standout combination for ageing skin, combining collagen renewal with deep multi-layer hydration. Adding Vitamin C extends the benefit to tone correction and sustained free-radical defence. All three can be mixed together into a single application of moisturiser.

What certifications do these boosters hold?

The Vitamin C booster is COSMOS Organic certified by the Soil Association, while the Hyaluronic Acid and Peptides boosters are COSMOS Natural certified. All three are Vegan Society registered, Leaping Bunny cruelty-free approved, and formulated in Pai's London lab. Every ingredient, including the actives themselves, is naturally derived: the hyaluronic acid comes from bacterial fermentation of maize glucose, the vitamin C from corn, and the peptides from yeast and Lactobacillus fermentation.

What clinical evidence supports the actives in these boosters?

The Vitamin C booster uses ascorbyl tetraisopalmitate, which skin cells absorb at roughly 10x the concentration of L-ascorbic acid, retaining it 40–80x longer. In three double-blind, placebo-controlled, split-face trials (23 subjects each, 8 weeks), concentrations of just 1–3% significantly reduced periorbital wrinkles versus placebo. The Peptides booster's Hexapeptide-11 delivered measurable elasticity improvements in a 4-week in vivo study of 25 volunteers (Sklirou et al., Redox Biology, 2015). Published research on the Hyaluronic Acid booster's multi-weight approach (JCAD, 2024) confirms that combining high, medium, and low molecular weights produces greater total hydration and lower water loss than any single weight alone.

What makes the Booster Discovery Kit different from other skincare starter sets?

Most kits give you diluted sample sizes or products that all target the same concern differently. This kit contains three full-concentration boosters that each address a biologically distinct mechanism: multi-depth hydration, oxidative defence and pigmentation control, and structural protein renewal. They're designed to complement each other, not compete, and every active is naturally derived and COSMOS certified.
