Product Description

Size: Full Size


One of the most bio-available non-prescription forms of vitamin A products on the market, A+ High-Dose Retinoid Serum is a pro-strength formula for those who want serious results without the unwanted side effects of traditional retinol formulations (reduced appearance of side effects like flaking, redness, and irritation compared to high-strength retinol and retinoid products is visible after one use).

Combining 5% retinoid ester blend, 1% liposomal-encapsulated retinol blend, and 0.5% blue-green algae with natural, retinoid-alternative activity, this serum fights the signs of aging and improves the look of congested and UV damaged skin. Still on the fence? In addition to reducing signs of ageing like fine lines and wrinkles, A+ features encapsulated CoQ10 to help improve the appearance of ageing or damaged skin, while Hawaiian white honey, bisabolol, cactus extract and ginger balance and soothe the skin for the appearance of a calmer, more even-toned complexion.

Any go wrong

Like another reviewer here I wanted this as an upgrade from Luna. Lovely serum like feel and though it’s strong, does not sting my sensitive skin. Really enjoying using it.

Shelf Staple

This product is one of my shelf staples and I'm happy to receive another. This works beautifully on my skin by reducing fine lines and revealing a brighter, more radiant complexion. Despite being a higher dose retinol product I have not had issues with my sensitive skin. The price is on the higher side but I would say it's definitely worth it, as it delivers results!

Brilliant product

This is one of my favourite retinol products. After using Luna for a while, I upgraded (in retinol strength) to the A+ so I was ecstatic to find this is this month’s box. My sensitive skin takes it well and is looking firmer and smoother.

Great perfect

I was nervous about trying a high dose retinol, but I was pleasantly surprised that this didn’t burn or sting my sensitive skin. I really noticed that my skin was so smooth the next morning. I don’t see any difference in the appearance of my skin yet- I’m hoping for some fading of some of my dark spots over time. I’m going to keep using this a couple times a week.
