Product Details and FAQs
Ultimate A+ is our high-strength Vitamin A serum with 0.1% retinal (Retinaldehyde) to target aging, acne, and pigmentation while improving skin texture and tone. It’s ideal for normal to oily skin types that aren’t sensitive.
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-strength Ultimate A instead.
We do not recommend Ultimate A+ 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+ offers high-strength 0.1% retinal for visible and tangible results. Its potency makes it perfect for those with normal to oily skin types who want to tackle multiple concerns like aging, acne, and pigmentation.
No. Ultimate A+ is free of fragrances, artificial colors, 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.
