This is a low but effective dose which is enough to provide skin with all the benefits of retinol without the irritation. The 1.5% on the packaging refers to the formula it sits in, which includes ingredients such as matrixyl 3000, a protein thought to increase collagen production and promote plump skin.
“Studies suggest you need to use at least 0.25% retinol or 0.025% tretinoin to be effective, so I recommend using a product that specifies the percentage.” When choosing a retinol product, Dr. Rogers says it's best to start with the lowest concentration before moving up.
According to Dr. Heather D. Rogers, a board-certified dermatologist in Seattle, Wash., retinol comes in multiple strengths; the most common are 1%, 0.5%, 0.3% and 0.25%. If your product doesn't specify the percentage of retinol on the label, it usually means the concentration is weaker than 0.25%.
High-strength retinol – 0.3%-1%
Those with stubborn skin concerns, like deep wrinkles and pronounced uneven skin tone may want to consider a high percentage retinol cream, serum or treatment. Look for those with a retinol percentage of between 0.3% and 1%.
While prescription-strength retinoids may have an effect in a matter of weeks, it can take up to 6 months for OTC retinols to produce the same results. You may notice a difference in conditions like acne after 12 weeks, but sun damage and signs of aging can take much, much longer to improve.
You'll likely want to use retinol once or twice per week initially and work up to using it more than that. The reason: Retinol can initially be drying, especially if you have sensitive skin, so it's a good idea to give your skin some time to adjust to the change in your routine.
The results showed that, after eight weeks, the retinol moisturizer was significantly more efficacious than the vehicle in improving lines and wrinkles, pigmentation, elasticity, firmness and overall photodamage. Many of these differences were significant at week 4, with a progressive improvement to week 8.
Moderate-strength retinol – 0.03% to 0.3%
If you experience skin concerns like uneven skin tone or texture and a visible loss of firmness, try adding a stronger retinol product to your routine such as 0.03% to 0.2% retinol products. Start by using 2-3 nights a week and build usage to see how your skin responds.
0.3% – a relatively low but effective dose of retinol. "0.3% retinol is enough to give a good effect but also enough not to put the skin at risk or irritate the skin," continued Abi. "There are creams out there formulated at 1% and 2% but in my experience consumers don't always use retinol properly.
The 1 percent retinol formula is designed to help with the signs of aging and clear up acne marks and hyperpigmentation. It's also free of parabens and fragrances, so it shouldn't cause redness or irritation. Reviewers note that while it's effective, it may take some time to see results.
Retinoids work best if you use them daily. Specifically, they should be used at night because some types are deactivated by light and air. It's important to start slowly and allow your skin time to adjust. Using too much too quickly can cause redness, dryness, and irritation.
Should you use retinol under your eyes? Yes, definitely. While it is true that retinol – a form of vitamin A – is a powerful ingredient and the skin under your eyes is delicate, there's no reason why you should miss out on the amazing benefits of retinol.
The truth: You can use vitamin C with retinol and retinoids. Get them as separate products so you can tailor the concentration of each and use them at the right time of day. Although vitamin C can be used day or night, it is ideal for daytime use, while retinol and retinoids should be applied at night.
Rouleau says the best time to use a scrub is in the morning. Overnight you've loosened up dead skin cells with your glycolic acid or retinol products, making the morning a perfect time to brush them off.
Retinol cream and serum work best all over the face. So, yes, put it on a dark spot you want to disappear or wrinkle you want to smooth, but also put it everywhere else because it can prevent future signs of aging.
Apply topical retinoids
Retinoids, which are topical vitamin A-based derivatives, may help reduce fine lines and wrinkles by increasing collagen production. If you use retinoids on your face, extend the treatment area to your neck and chest at night. Retinoid products are available by prescription or over the counter.
The problem is, retinol can be irritating when applied straight to the lips (so keep your prescription-strength cream off your mouth for the time being). But Verso's formula contains a gentle derivative, called retinol 8, which can reduce the appearance of fine lines around the mouth overtime.
Retinol is the gold standard of anti-aging ingredients, and this silky serum has plenty of it. The vitamin A derivative works to stimulate collagen production under the eyes, making dark circles less visible.
How Do Retinoids Work. New skin cells form deep within the skin layer and with time they finally come to the surface. This process usually takes about one month. Retinoids work by increasing the rate of skin cell turnover.
Purging is slightly different, appearing on the skin mostly as blackheads or small skin-coloured bumps just under the surface of the skin. But it is also possible for purging to cause similar spots to a breakout, too.
"[but] best to re-start your retinol again when you can." Most dermatologists recommend using it at least twice weekly to see results.
Keep Your Face Clean
Touching your face or allowing oil or bacteria to build up can also increase the side effects of the tretinoin purge. Only touch your face with clean hands and leave your skin to do its thing. Also try not to pick at flaky or dry skin caused by the purge.
