“AHA, BHA, retinol, and benzoyl peroxide can be mixed with moisturizing ingredients like hyaluronic acid, ceramides, and rosehip oil to get effective results — just ensure you are not using retinol as well as AHA or BHA's during the day," says Graf.
Retinoids and serums can be used together, especially if the serum is soothing or hydrating. Be careful using very aggressive face oil serums with retinoids.
Bakuchiol is the most notable retinol alternative. You've probably seen it everywhere. It comes from the seeds of the Babchi plant and stimulates the regeneration of skin cells. Much like retinol, it stimulates collagen production, evens out skin tones, improves the appearance of fine lines and reduces inflammation.
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.
Pairing the two ingredients is safe and can make retinol easier to use. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol. Niacinamide and retinol can be combined in one product or used as separate products.
What Are the Benefits of Combining the Two? Good news: Retinol and hyaluronic acid actually have a synergistic effect. “They can be combined so that the benefits of retinol can be achieved more easily with concomitant use of hyaluronic acid, which helps to prevent retinol irritation,” says Hartman.
In general, you can use both together, but if you suffer from irritated skin, then scale back the number of retinoid products that you're using, or take a break and slowly reintroduce it into your routine. When it comes to holy grail ingredients, retinol can really seem like it has it all.
What are some of the side effects of retinoids? Retinoids, in particularly oral retinoids, can have rare but serious side effects. There is a potential link between anxiety, depression, anger, mood changes and retinoid use.
Retinal + Retinaldehyde
Retinal is stabilized and is known to help provide clearer looking and feeling skin. “Retinal is more effective than retinol and less irritating than a prescription Rx, which makes it reliable at delivering swift results,” says Cline.
The reason why people suggest a maximum of two or three serums comes down to layering and penetration. Heaps of brands, salons and experts recommend leaving time between applying your serums and moisturisers, and doing it in a specific order so as to allow all of the ingredients to actually sink into your epidermis.
You should use hyaluronic acid after retinol. And to maximise the benefits, you should use retinol first and then wait at least 30 minutes before applying hyaluronic acid.
No matter which form you choose to incorporate your hyaluronic acid, it should be close to the final step in your routine. If you are using it in serum form, you'll apply it immediately after your retinol. If it is part of your moisturizer, it will be your last step.
Hyaluronic Acid and Niacinamide
These water-based treatments are a great pair and are made for all skin types — especially babes with dry, acne-prone skin. You'll find niacinamide, a form of vitamin B3, in my Rewind Retinol Serum. Use hyaluronic acid first, followed by my retinol for the best results.
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.
Pairing the two ingredients is safe and can make retinol easier to use. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol. Niacinamide and retinol can be combined in one product or used as separate products.
Retinoids, Vitamin A and its derivatives, have been linked to neuropsychiatric symptoms including depression [11]. Excess accumulation of Vitamin A has been reported to induce depression [12].
“There is no evidence that supports that a topical retinol can cause depression whatsoever,” said Dr. Adam Friedman, professor and chair of dermatology at George Washington University's School of Medicine and Health Sciences. Retinol is just one of many retinoids used to treat skin.
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.
Main Differences Between Vitamin C Serum and Retinol Serum
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.
Retinol is a gentler derivative of vitamin A and can be found in lots of over-the-counter skin care products (i.e. moisturizers, serums, eye creams). Because retinol is milder, the enzymes in our skin must first convert it into retinoic acid. Once it's been converted, then it will be become effective.
Vitamin A comes from two sources. One group, called retinoids, comes from animal sources and includes retinol. The other group, called carotenoids, comes from plants and includes beta-carotene. The body converts beta-carotene to vitamin A.
When it comes to mixing all three together, the best order to apply them is by starting with retinol, followed by hyaluronic acid, and finally niacinamide. By applying retinol first onto a fully cleansed skin the ingredient can penetrate into the lower layers.
Using niacinamide before retinol works well. So does combining them into one product. A 2016 study found that a product containing retinol, niacinamide, hexylresorcinol, and resveratrol improved fine lines, sallowness, wrinkling, hyperpigmentation, and skin tone.
