Below, you’ll find products with 0.15% retinoid for beginners, through to 1% blends for more experienced users. Is it okay to use retinol every night? What's more, the anti-aging effectiveness is not the only questionable thing about RP. It also exibits questionable behaviour in the presence of UV light and was the center of a debate between the non-profit group, EWG (whose intentions are no doubt good, but its credibility is often questioned by scientists) and a group of scientists and dermatologists lead bySteven Q. Wang, MD, director of dermatologic surgery at Memorial-Sloan Kettering Cancer Centre.

As we wrote in our lengthy retinol description the problem is that the conversion is not terriblyeffective. The evidence that RP is still an effective anti-aging ingredient is not very strong, in fact, it's weak. Dr. Leslie Baumann in her fantastic Cosmetic Dermatologybook writes that RP is topically ineffective. We think that the truth lies somewhere in the middle, and we agree with Dr. Baumann's conclusion: " sufficient evidence to establish a causal link between RP and skin cancer has not been produced.

Retinoids can cause burning, stinging and peeling when first applied,” says Dr Mahto. “Build up their use slowly – a few times weekly – until you are able to use them nightly. If the product makes your skin sore, give it a break; if not, you are OK to continue using it. Speak to a dermatologist if you have sensitive skin or an underlying inflammatory skin condition, such as eczema, psoriasis or rosacea, as retinoids can potentially cause problems.” If you want to use both retinol and brightening vitamin C in your skincare routine, apply the latter ingredient in the morning to give your skin a breather.

Depending on the concentration and formulation, retinol is generally a milder choice than retinal. This is because it takes longer to convert to the most potent retinoic acid in your skin, reducing the risk of irritation. Experienced retinol users, however, may prefer the faster results of retinal. Moisturising hyaluronic acid and ceramides can help to lessen the severity of retinol side effects. However, Dr Mahto recommends waiting 15 to 20 minutes after applying your retinol serum before applying your chosen moisturiser, so as not to minimise the retinoid's efficacy. What can you not mix with retinol? Dr. Leslie Baumann wrote a great review of the debate and summarized the research available about retinyl palmitatehere. It seems that there is a study showing RP being photo protective against UVB rays but there is also a study showingRP causing DNA damage and cytotoxicity in association with UVA.Retinol and retinal (abbreviated from retinaldehyde) can be bought over-the-counter and are weaker than retinoic acid, which is generally a prescription-only agent,” she says.
