Size: 60 capsules

A super charged evening Retinol Serum treatment containing OSKIA’s advanced Super-Nutrient Retinoid Complex (with 0.5% Hydroxypinacolone Retinoate HPR, Vitamins C, E & Pro-Vitamin D3) with high concentrations of cellular nutrients, plus botanical actives and key anti-oxidants to help maintain a firm, plump, youthful, clear and healthy-looking complexion.

You asked for a powerful yet non-sensitising retinol treatment that could be added to your daily routine. Our answer was to produce these stable, oil-soluble nightly retinoid serum capsules, so light in texture that it can be layered into your routine and not replace a night cream or oil.

Non-greasy and deeply penetrating, use these super-charged serum capsules as part of your evening skin routine.

Capsules are made from seaweed, are biodegradable and compostable. Fragrance Free.

For those new to retinol/retinoid treatments, we recommend you start with Sleep Serum Level 1 which contains 0.2% HPR.


  • Helps plump and reduce the appearance of fine lines and wrinkles.
  • Supports collagen production for firmer skin.
  • Helps regulate excess sebum production for a clearer complexion.
  • Helps brighten skin and even skin tone.
  • Provides anti-oxidant protection.


  • 0.5% of Hydroxypinacolone Retinoate, a fourth-generation Retinoid, provides unrivalled skin health benefits, including wrinkle, dark spot and acne reduction. It is oil soluble so absorbs very quickly and the only retinoid apart from Tretinoin or Retinoid Acid that does not need to go through any metabolic changes before it can be effective. It binds directly onto the retinoid receptors of the skin cells. 0.5% is the maximum level allowed under EU legislation for cosmetic products.
  • Pro-Vitamin D3, a naturally-occurring active essential for the synthesis of Vitamin D, supports skin health.
  • Encapsulated Ascorbyl Tetraisopalmitate, a super-charged, stable and oil-soluble, form of Vitamin C, penetrates deeply to visibly firm and brighten.
  • Turmeric heightens skin radiance and tone.
  • Defiensil™, rich in Omega 3, soothes and calms.
  • Alaria Esculenta and Rosamox™ firm and hydrate.
  • Encapsulated Co-Enzyme Q10 & Vitamin E provide anti-oxidant and anti-glycation protection.
  • Hemi-Squalane– plant derived, saturated fat that restores the lipid barrier, balances the skin’s natural oils and improves hydration and smoothness. Saturated oils have single bonds within their fatty acid chains, which makes them more stable and resistant to free-radical attacks.


All skin types and tones. We recommend a lower age limit of 28, unless treating acne, scaring or hyper-pigmentation. Fragrance free.


Use in the evening as part of your skincare routine. Twist capsule and apply serum on treatment area, 2 or 3 evenings per week if new to retinol, or nightly if preferred. Follow with your preferred OSKIA moisturiser or oil. Reduce frequency if sensitivity occurs. Can be used after water-based serums, and before facial oils or moisturisers.

We recommend for those 28 years and above, unless treating acne, scaring or hyper-pigmentation.

NOTE: Do not use during pregnancy, lactation or with other retinol or retinoid treatments. Use sun protection during the day.


Hydroxypinacolone Retinoate (also known as HPR or Granactive Retinoid) is a 4th generation of retinoids – it is oil-soluble & quick absorbing. It is the only one, apart from Tretinion or Retinoid Acid, that does not need to go through any metabolic changes before it can be effective. It binds directly onto the retinoid receptors of the skin cells.

What does it do?
It inhibits collagen-destroying enzymes called matrix metalloproteinases (MMPs).
It boosts the skin’s own collagen synthesis (type I & III).
It stimulates natural moisturising factor glycosaminoglycans (GAGs) and skin protein filaggrin.
It makes the epidermis thicker and compacts the outermost layer of the skin.
It reduces sebum production so great for spot-prone skin – though it is important to replenish the lipid barrier which is why we use hemi-squalane which is wonderful saturated, plant sourced, fat.


Avoid eye contact, if this occurs, rinse well with warm water. Do not use on broken skin. Keep away from children. Do not use during pregnancy, lactation or with other retinol / retinoid treatments. This product may make your skin more sensitive to the sun, please use SPF during the day.
