Frequently Asked Questions

Products 

Which product should I start with if I’m new to REJNA?

If you’re unsure and just beginning your journey with REJNA, we recommend starting with the BioTech Exosome Serum, our advanced formula designed to visibly renew skin at the cellular level. It integrates seamlessly into any routine and delivers results you can feel within 7-14 days.

Pair it with the Stem Cell Moisturiser for optimal glow and barrier repair.                       

I don’t have time for a complicated routine, will REJNA still work for me?

Absolutely. REJNA is built on a minimal, high-performance routine. Sometimes, you only need 2-3 products to see results. For example:

Morning: BioTech Exosome Serum, BioTech StemCell Moisturiser, Daily Defence SPF 50

Evening: AHA Cleanser, Bakuchiol Oil or Retinol Oil Serum, Eye Cream

Less confusion. More clarity.

Product Integrity & Skin Suitability

Are REJNA products suitable for sensitive skin?

Yes. Every REJNA formulation is meticulously designed to minimise irritation, support skin barrier repair, and respect the integrity of even the most reactive skin types. We avoid common sensitisers such as fragrance and aggressive actives. Our products are pH-optimised and designed with dermatological expertise.

Can I use REJNA products on melanin-rich skin tones?

Absolutely. Our formulations are designed with universal skin biology in mind, including skin that is more prone to hyperpigmentation, scarring or sensitivity. We avoid actives that increase inflammation risk and instead prioritise soothing, brightening and regenerative ingredients.

Are REJNA products pregnancy and breastfeeding safe?

Most of our products are formulated to be suitable during pregnancy and breastfeeding. We exclude prescription-strength retinoids, aggressive exfoliants, and endocrine-disrupting compounds. However, we always recommend consulting with your healthcare provider prior to introducing any new product during this time.

Ingredient Science & Formulation Philosophy

What are exosomes and how do they benefit skin?

Exosomes are nano-scale vesicles naturally secreted by cells to facilitate intercellular communication. In our biotech-derived complexes, exosomes from fermented botanical sources, e.g. green tangerine and radish root, carry peptides, enzymes, and growth factors that stimulate skin regeneration, improve post-treatment recovery, and support tissue renewal without irritation.

Why don’t you use fragrance in your products?

Fragrance, even when natural, is a leading cause of skin sensitisation. At REJNA, we formulate without synthetic or essential oil fragrances to protect barrier function, especially in compromised or reactive skin. Any subtle aroma in our products comes from functional botanicals or carrier oils with intrinsic skin benefits.

What makes REJNA formulations different from other skincare brands?

REJNA combines dermatology-backed actives with heritage botanicals and modern biotechnology. Our focus is skin biology, not trends. We formulate with high-efficacy, clinically supported concentrations of ingredients like Matrixyl® 3000, niacinamide, and stem cell extracts, and leave out everything that doesn’t serve your skin’s long-term health.

Every product is:

·      Dermatologist-guided

·      Clinically active, not aggressive

·      Fragrance-free

·      Made in the UK

·      Safe for real-world skin concerns  

Are your products vegan and cruelty-free?

Yes. All products are 100% vegan, cruelty-free, and without any parabens and sulphates. Our lab partners and ingredient suppliers adhere to strict ethical and regulatory compliance standards.

Where are your products made?

REJNA is formulated and manufactured in the UK, under ISO-certified laboratories, adhering to Good Manufacturing Practice (GMP) standards. Each product undergoes rigorous stability, compatibility, and safety testing before release.  

Usage & Results

When will I see results?

While some users notice visible improvement in radiance and skin texture within 1-2 weeks, most clinical-grade ingredients show cumulative effects over 4-8 weeks. For best results, consistency and proper application order are key.

What is the recommended routine order for REJNA products?

We recommend applying products in the following order:

Cleanser → Serum, e.g. Exosome → Moisturiser → Oil (optional) → SPF (AM)

At night, you may introduce retinoids (like our Retinol Oil Serum) after serum and before moisturiser.

Do your products clog pores or cause breakouts?

No. Our products are non-comedogenic and carefully formulated to support the skin’s microbiome. We avoid occlusive silicones and pore-clogging oils, opting instead for breathable emollients and barrier-repair lipids.
