ULTIMATE A+ Product Details and FAQs
Hydraboost is ESK’s deeply hydrating Hyaluronic Acid serum, formulated with three molecular weights to penetrate different skin layers for maximum hydration. Lightweight and fast-absorbing, it helps plump, soothe, and support your skin barrier, making it the perfect companion to Ultimate A+. Hydraboost is suitable for everyone and can be used morning and/or night, before or after Ultimate A+!
Ultimate A+ is our Retinal (Retinaldehyde) night cream which targets aging, acne, and pigmentation while improving skin texture and tone. It’s ideal for all skin types unless pregnant or breastfeeding.
Ultimate A+ is best suited for normal to oily skin types looking for maximum anti-aging, acne-fighting, or brightening benefits. If you have sensitive, dry, or rosacea, psoriasis, or eczema-prone skin, we recommend starting with our lower-strengthUltimate A instead.
We recommend to use Ultimate A instead for sensitive skin. If you’re unsure, patch test first or opt for Ultimate A, which is gentler and designed for sensitive and reactive skin types.
At night, apply Gentle Glow or Smooth Serum before Ultimate A to enhance the effectiveness of retinal and achieve even better results. In the morning, follow with one of our niacinamide-based products like Vitamin B or Vitamin C Forte (see the Mature Kit for maximum anti-aging benefits).
Results typically appear within 6–8 weeks of consistent use, with continued improvements in skin texture, tone, and clarity over time.
Retinal (Retinaldehyde) is a more advanced form of Vitamin A than retinol. It’s 11x faster and more effective at delivering results, with fewer steps to convert into the active form of Vitamin A in the skin.
Ultimate A+ uses retinal (retinaldehyde), proven to work faster and more effectively than retinol without the dryness or irritation. Our perfectly balanced formula delivers powerful results while staying gentle on your skin, making it ideal for all skin types, including sensitive ones.
No. Ultimate A is free of fragrances, artificial colours, and known irritants, designed to deliver results without unnecessary additives.
Like all Vitamin A products, retinal isn’t recommended during pregnancy or breastfeeding. If you’re pregnant or nursing, check out our pregnancy-safe kits instead.
