HPR (Hydroxypinacolone Retinoate) is a next-generation retinoid ester that binds directly to retinoic acid receptors in the skin — meaning it works like prescription tretinoin without needing the multi-step conversion that regular retinol requires (retinol → retinaldehyde → retinoic acid). The result is faster anti-aging results (smoother fine lines, firmer skin, improved texture) with significantly less irritation, dryness or peeling than retinol. HPR is also more photostable and can be used morning or evening, unlike retinol which is strictly nighttime-only.

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell that powers cellular energy production and DNA repair. NMN (Nicotinamide Mononucleotide) is a precursor that the body converts into NAD+. Both have become hot topics in longevity science because NAD+ levels naturally decline with age, contributing to slower cell turnover, mitochondrial dysfunction and visible aging signs. Applied topically (as in epii's Double Up Cream NAD+ NMN), these actives support skin cell energy, accelerate repair and boost overall skin vitality — visible results typically appear after 4–8 weeks of consistent use.

Ectoin is an extremophile-derived molecule (originally found in bacteria that survive in extreme environments like deserts and salt lakes) that has powerful skin-protective properties. It forms a protective hydration shell around skin cells, defending against UV damage, pollution, dryness, oxidative stress and barrier compromise. Ectoin is especially well-suited for the UAE and GCC climate — harsh sun, dry desert air, air conditioning — where it strengthens skin resilience. epii's Double Up Cream Ectoin & Panthenol pairs ectoin with panthenol (B5) for a calming, repair-focused formula suited for sensitive or stressed skin.

Yes — unlike traditional retinol, HPR is photostable, meaning it doesn't break down in sunlight. This allows for both morning and evening use, though most users still apply it in the evening as part of their PM treatment routine to maximise overnight repair benefits. Apply 2–3 drops to clean, toned skin before moisturiser. Pair with daily SPF50+ in the morning (essential for any anti-aging routine). HPR is generally considered safer than retinol during pregnancy, though always consult your doctor before adding any retinoid during pregnancy.

Snow mushroom (Tremella fuciformis) is a Chinese medicinal mushroom with hydration properties similar to hyaluronic acid — it can hold up to 500 times its weight in water, with smaller molecules that penetrate skin more deeply than HA. PHA (polyhydroxy acid) is a larger-molecule chemical exfoliant that's gentler than AHA or BHA, suitable for sensitive skin and beginners to acid exfoliation. The epii New Skin Toner pairs snow mushroom for hydration with PHA for gentle resurfacing — ideal as a daily toner that smooths texture and plumps skin without irritation.
