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.
1) Always start slowly.
It can take time for your skin to get used to a retinoid. Start by applying it once or twice a week. As your skin adjusts, you can work your way up to using it nightly. Once you're comfortable with nightly use, you can consider increasing the strength.
Apply it once a day at night. If your skin is sensitive or you are new to retinoids, you can start by applying it 1-2 times per week to avoid irritation.
Use retinol once or twice a week at first to see how your skin reacts, and gradually work up to every other day or three times a week. Another key tip for using retinol is to incorporate it into your nighttime skincare routine only, as it makes your skin more sensitive to sunlight.
It may seem surprising, but even small percentages of retinol can benefit your skin. Percentages of 0.01% retinol or greater are proven to be effective at improving multiple signs of ageing, reducing pore size and improving the overall health of your skin.
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.
Retinol is best applied at night since it can increase your skin's sensitivity to the sun. When you do go outside, be sure to use sunscreen to protect your face. It's worth noting that you don't need to use retinol on a daily basis for it to effectively treat your acne. Even two to three times per week might be enough.
"[but] best to re-start your retinol again when you can." Most dermatologists recommend using it at least twice weekly to see results.
Heat, and light can speed up the expiration by weakening the active ingredient over time. Keeping your retinol moisturizer or benzoyl peroxide acne spot treatment in a dark and cool environment like the fridge will slow down the degradation of the active ingredient.
“Since retinol is pushing up skin cells to the surface at a faster rate, retinol can cause micro-peeling (invisible peeling) in most skin types, so it's important not to use it every night.”
A formula with retinol, like the L'Oréal Paris Revitalift Triple Power Eye Treatment, should be applied after your serums and before moisturizer due to its consistency.
While there's no right or wrong age to begin using retinol, most dermatologists recommend fitting it into your skin care routine during your 20s. The reason? "The production of collagen fibers starts to decline in our 20s," explains Dr. Allison Arthur, MD, FAAD, at Sand Lake Dermatology Center.
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.
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, around six months. Mascara, around three months. Sunscreen [is about] two to three years.” What can you do to prolong a product's shelf life, if possible?
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.
“If you're overusing your retinol, or if you're using a retinol that's too strong for you, it can lead to peeling, irritation, and excessive dryness, which may have led to retinol's association with skin thinning,” she says.
Using any form of retinol makes your skin more prone to sunburn. Sun damage combined with retinol burn is a recipe for redness or discoloration, inflammation, and more.
While Vitamin C serum predominantly protects your skin from damage, retinol serum actively heals the damage on your skin. Vitamin C serum protects the collagens while the Retinol serum helps in cell turn over thereby creating new collagens.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out skin and cause further irritation if your skincare routine already includes retinol. As for benzoyl peroxide and retinol, they cancel each other out.
“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. Another thing to consider is your skin type.
It's 0.3% retinol (a percentage specifically chosen because No7's trials showed it produced effective results with little irritation) mixed with other milder retinoids and active ingredients.
Retinoids (the umbrella term for all vitamin-A derivatives, like retinol) sink into your skin and trigger faster cell turnover and collagen production, creating newer, smoother, skin. And all of that means pores stay clear, breakouts diminish, fine lines soften, and acne scars fade.
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.
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.
