Why You'll Love It
A GLASS OF WATER FOR THIRSTY SKIN
Hydration isn't just about adding water. It's about helping skin hold onto it.
Back to Life is a next-generation hydration serum that combines 100% natural, Bio-Fermented Hyaluronic Acid with barrier-supporting prebiotics to restore moisture where skin needs it most. The result is deep, lasting hydration that leaves skin visibly plumper, smoother and more comfortable from the very first application.
Our Hyaluronic Acid is created through natural fermentation, producing a skin-identical moisture magnet that attracts and retains water to help replenish dehydration and soften the appearance of fine lines. Unlike many conventional hydrating serums, we've removed common sensitising ingredients like propylene glycol, replacing them with skin-compatible Jojoba Oil and microbiome-supporting Inulin to strengthen the skin barrier as you hydrate. Essential for healthier, more resilient skin over time.
Proven to deliver hydration without irritation, helping even dry, reactive skin feel calmer, softer and comfortably hydrated. Because truly healthy skin doesn't just gain moisture, it learns to keep it.
Independently tested on sensitive skin, for 4x longer than standard.
100% Natural. COSMOS Organic certified. Vegan. Cruelty-free.

Key Ingredients
-
Bio Fermented Hyaluronic Acid
Ultra-low molecular weight Hyaluronic Acid absorbs quickly for deep, long-lasting hydration. It can hold up to 50 times its weight in water, storing it like a reservoir for the skin, helping to plump and smooth.
-
Prebiotic Inulin
Helps to preserve and protect the skin to form a natural, defensive shield and support skin’s overall resilience.
-
Jojoba
We use jojoba oil to smooth and soften because its composition is so similar to our own skin’s natural sebum. This means our skin welcomes it onboard, absorbs it easily and doesn’t kick up a fuss.
"Dehydration is a skin concern that's often overlooked and misunderstood. It’s very common, and can affect any skin type where the skin is lacking in water. Designed to penetrate as quickly and deeply as possible, our serum is tolerated and loved by even the most sensitive skins.”

Q&A

- Is this safe for acne prone skin?
- Hi Kenzie, Yes this is safe and suitable for acne prone skin. We would recommend using this if your skin needs hydration, otherwise, if you're looking for a product that will help to target acne, we would recommend our All Becomes Clear Serum. Pai Customer Experience Team
- Does this serum have vitamin C in it?
- Hi Emma, Thank you for getting in touch. Instant Kalmer Serum is a Vitamin C free product. We do have a Vitamin C Booster you may like to use in your Moisturiser or Rosehip Oil.
- Why using at night? Is it only for night? Thanks
- Hi Yevheniia, Thank you for getting in touch. You can use Back to Life Serum in the morning and in the evening before your Moisturiser. You can use it alone at night or apply Rosehip Oil or Moisturiser on top. You may prefer to use our Hyaluronic Acid Booster in your daily Moisturiser.
- Hi, I was wondering if can you use Back to Life serum on its own without a moisturiser on top please? I'm 51 with perimenopausal skin, I do t like to feel to much on my face but still would like hydration. Thank you.
- Hi Sally! We don't recommend using our Back To Life Serum in place of a moisturiser as it won't protect against moisture loss in the same way that a moisturiser will. We like to think of serums as feeding the skin, whilst creams protect it. However, you can alternate by using the serum alone in the morning and moisturiser in the evening, or vice versa. If you would like some guidance choosing the best moisturiser for your skin, please book a [free online consultation](https://www.paiskincare.com/pages/skincare-consultation?utm_source=zendesk&utm_medium=referral&utm_campaign=zendesk-email) with one of our skin coaches and we would be delighted to help!
