Topical retinol is generally safe for long-term use without any detrimental health risks.
First-time retinol users have reported irritation, including redness, dryness, and peeling. If you use too high a strength or apply retinol more frequently than you should, you may experience further irritation, like itchiness and scaly patches.
If you're wondering if you're clear to use your retinol as a long-term anti-aging strategy without negative side effects (like compromising the strength of your skin), all derms agree the answer is yes — in fact, you'll need to use it continuously if you want to keep benefiting from the effects, says Dr. Colbert.
If you stop retinol and do not begin a prescription retinoid, the benefit of preventing acne will go away. The skin cycle of cells being “born” at the base of the skin and moving to the top, dying and desquamating into the surrounding environment takes about 4-6 weeks.
It's best to start with a retinyl palmitate or retinol, and to try it for three months and then have a three month break. This is due to research that suggests cell turnover is no longer increased after three months of usage.
Also avoid retinol if you're going to be spending a lot of time in direct sunlight without proper sun protection. Retinol can make your skin more sensitive to the sun, so it's important to use sunscreen with at least SPF 30 every day — even when it looks cloudy.
Is it safe to use retinol every day? For most people, yes — once your skin is used to it, that is. That said, there are some people who may not want to use it frequently or at all.
“This will make your skin look older and accentuate wrinkles” — which is probably not what you're going for when you start using the stuff. And there's no question that retinol makes your skin more sensitive to the sun.
So if you start using retinol every day out of the gate, you can end up with some painful inflammation and a damaged skin barrier, negating any potential positives. One way to avoid that irritation is to start slow, explains Ranella Hirsch, MD, a board-certified dermatologist in Boston.
Retinol might not be a fit for those with overly sensitive or hypersensitive skin, those who have food intolerances or high allergic reactions, and young skin, she says. “Caution is necessary when using any vitamin A derivatives and should only be used after advice from your derm or skin care specialist,” Joss says.
Retinoid acid, the bioactive metabolite of vitamin A, is a potent signaling molecule in the brains of growing and adult animals, regulates numerous gene products, and modulates neurogenesis, neuronal survival and synaptic plasticity.
Retinol is better tolerated and produces considerably less transepidermal water loss, erythema, and scaling than retinoic acid (tretinoin.) Cons: Retinol is significantly less potent than tretinoin and it requires further conversion to retinoic acid to demonstrate its action.
What are the negative effects of retinol? Incorrect retinol usage can cause drying, flaking, shedding, redness, and irritation of the skin as well as exacerbated acne. Retinol will also increase skin sensitivity to UV rays.
First, the answer is yes, retinol can make wrinkles worse, especially when you first start using it. What is happening is a drying effect, and one can get epidermal sliding from separation from the dermis.
What age is it recommended to start using retinol? There are no set rules on how old you should be to use retinol. For anti-aging purposes, you can start preventatively in your 20s. While over-the-counter retinol can help mild acne, many people with breakouts will need a prescription.
Retinol is also one of the best ways to “reduce the appearance of fine lines, crow's feet, and wrinkles,” says Henry. It's a must in your 50s if you haven't already been using it. Engelman says prescription-strength retinols are “vital” at this stage.
Because retinoids help your skin make more collagen, they soften wrinkles and fine lines. They also stimulate new blood vessels, which can give your skin a rosy color. Retinoids also help fade age spots and smooth rough patches. Tretinoin (Retin-A) is a popular prescription choice for aging skin.
Don't start Retin-A.
Since mature skin is naturally dry anyway, most women over 70 who have never used it before will need to avoid the Retin A.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out the skin and cause further irritation if your skincare routine already includes retinol.
Retinol significantly decreased both hormone levels, however retinoic acid decreased the progesterone level only.
In many cases, damage that has already occurred can't be reversed, making early detection important. Your doctor will work with you to determine the best treatment. Treatment of retinal disease may be complex and sometimes urgent.
Yes, in many cases an eye doctor can repair a damaged retina. While a patient may not experience completely restored vision, retinal repair can prevent further vision loss and stabilize vision. It's important that patients get treatment for their damaged retinas as soon as possible.
Retinol is well known for worsening the condition of the skin before improving it. Most people who introduce retinol to their skin, experience severe breakouts, dryness, itchiness, and redness. The immediate side effects of retinol treatment can take the form of a surge in acne, blackheads, whiteheads, and rashes.
Hyaluronic acid is best if they're looking to moisturize dry skin, while retinol works better by encouraging better skin by boosting collagen production. They have several benefits that can work in tandem for better results, though patients need to be careful with the exact formulations they use.
