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.

A plus for everything except for the price
I first received a mini sized tube of the A plus serum in the Space NK 2021 advent calendar and was impressed enough to have since then bought a travel size within a Sunday Riley trial set. After using 20ml of this product, I would gladly use it in the future as well, but the price feels quite salty. As for the light yellow coloured serum itself, the consistency feels light and the product treats my skin gently. I am not a particularly seasoned retinol user yet, but could easily apply this serum consistently every night (often consecutively with the Sunday Riley Luna Sleeping Retinoid Night Oil) without any negative side effects. As for seeing dramatic results, I cannot attest to that as of yet, but on the other hand I am generally quite baby faced for my 35 years of age. Based on my experience using this serum thus far, it does seem like a quality product, and I would entrust it to keep my skin from the bane of early signs of aging.

Great Product
Amazing product, I’ve been using this now for a good few months and have found it makes a difference on dark spots under eyes, my face feels refreshed in the morning. I feel like my face is former and fine lines have been reduced. Lovely product would definitely recommend.

Gentle yet effective
I’ve been through a couple bottles of this and love it as it’s never caused irritation but I can see results the very next day. I only use it a couple times a week as I’m trying not to overdo it with actives but this is one of my holy grail retinoid products that I don’t feel compromised my skin barrier. The results I see are a brighter complexion, plumper looking skin

High dose retinol - one of the best
This is by far a great best high dose retinols in the market. Although I was silly not to have realised it was a high dose, the texture felt great and it did take only 4 days after to feel the burn. As per experts, I should have eased into it and mixed it with the moisturiser. There isn't an overpowering smell and the bottle squeezes the right amount out. Sunday Riley is just one of the best in the market and I'd definitely give it another go once my skin feels used to a lower dose.
Best Use: Anti-Aging

Love love love…my new nightly go to!
This is my 3rd purchase of the same product…that says a lot. I love good genes for my daily and A+ at night. Started with good genes (I’m obsessed) and then added on others products. Easy with incredible great results. You won’t be disappointed.
