The 3 Anti-Ageing Skincare Products You Need

With many skincare products marketed as anti-ageing, what do we actually need in our routine? There are 3 staples we recommend for the ultimate anti-ageing skincare regime – retinol, vitamin C and hydroxy acids. Each tackles the 3 major signs of skin ageing. These 3 signs being fine lines and wrinkles, uneven skin tone and dull skin. Keep reading for product recommendations and to learn how these skincare products do their thing.

Retinoids for collagen loss (fine lines and wrinkles)

Retinoid is used as an umbrella term for any compound derived from vitamin A (a vitamin A derivative). A vitamin A derivative possesses structural or functional similarities to vitamin A, but is not quite vitamin A. In some contexts, the term retinoid can also refer to prescription-strength vitamin A derivatives (such as tretinoin and tazarotene).

I’m sure you’ve also heard of retinol. It turns out that vitamin A and retinol are actually the same compound (they are just two different names for the same thing). Thus, retinol and any vitamin A derivatives you can think of – retinal (aka retinyladehyde or retinaldehyde), adapalene, retinoic acid, retinyl esters (such as retinyl propionate and retinyl palmitate), tretinoin and tazarotene – can be classified as a retinoid. Despite retinol not being a vitamin A derivative, but vitamin A itself, it is generally still considered a retinoid.

How do the different types of retinoids differ?

As I’ve alluded to above, vitamin A and retinol (aka all-trans-retinol) are technically the same compound.

However, retinol is not the most active form of vitamin A (if we want amazing skin). When we use retinoid products in the pursuit of perfect skin, it is not vitamin A (retinol) we can thank for this. For the most part, retinoic acid (all-trans-retinoic acid) is actually the compound producing the effects we want. So there has to be some chemistry going on once we apply these products, in order to produce retinoic acid (see below).

anti-ageing skincare products - retinol conversion to retinoic acid

Retinol is converted to retinoic acid in two steps: firstly, alcohol dehydrogenase (ADH) or retinol dehydrogenase (RDH) enzymes catalyse the oxidation of retinol to retinal. The reverse reaction may also occur. Subsequent oxidation of retinal by retinaldehyde dehydrogenases (RALDH – of which there are several types) furnishes retinoic acid (this is an irreversible step).

With retinyl esters, these are first converted to retinol, which then undergoes the same two-step process as above. Or, as you can imagine, retinals only have the one step to go through to produce retinoic acid.

Retinoic acid for fine lines and wrinkles

Retinoic acid seeks to activate the three retinoic acid receptors (alpha, beta, gamma). Since it is a lipophilic molecule, it can diffuse through cellular and other phospholipid membranes. Once retinoic acid has bound to its receptors, inside the cells, modulation of gene (genes involved in cellular differentiation and proliferation) expression occurs. This results in the reduction of fine lines and acne, as well as increased cell renewal, collagen production and more. Everything we have come to expect of retinoids.

Which retinoid should I use?

If you have sensitive skin don’t go for prescription retinoids – start with something less potent such as retinol (this is the go to for many). Since retinol (retinal and retinyl esters too) has to be first converted to retinoic acid, the concentration of retinoic acid at any one time is much lower and thus less irritating. Taking this even further, a lower concentration of any retinoid is always better for sensitive skin. It will take a little longer to see results from using retinol compared to retinoic acid, but will be all that most people require to see some good results.

Vitamin C for uneven skin tone

We know we should be eating plenty of vitamin C, but what’s the deal with vitamin C serum?

Free radicals are highly reactive molecules with unpaired electrons that are known to damage various cellular structural membranes, lipids, proteins, and DNA. It is one of the widely accepted mechanisms that lead to skin ageing.

The body can be exposed to free radicals from environmental exposures (as well as intrinsic exposures), such as cigarette smoke, air pollution, and ultraviolet radiation from the sun. Consequently, the body employs antioxidants which aim to protect cells from the damaging effects of free radicals.

Vitamin C reacts rapidly with free radicals; it is widely understood that vitamin C’s antioxidant properties are partly responsible for its biological activity.

How does vitamin C help with uneven skin tone?

Hyperpigmentation – a darkening of the skin that occurs due to an excess of melanin, for example, in the case of age spots, freckles, melasma, and post-inflammatory hyperpigmentation. Cosmeceuticals are commonly used to target hyperpigmentation; hydroquinone being a common example in the treatment of hyperpigmented skin conditions. However, hydroquinone has recently come under fire due to chronic adverse side effects such as discolouration of the skin, cataract, pigmented colloid milia, loss of elasticity of the skin, impaired wound healing as well as safety concerns.

Studies using vitamin C for hyperpigmentation

Studies have show that vitamin C acts as a reducing agent at various oxidative steps of melanin formation, hence inhibiting melanogenesis. Dermatologists therefore use vitamin C frequently for depigmentation of hyperpigmented spots on the skin.

A study compared the use of 5% ascorbic acid and 4% hydroquinone in female patients with melasma and found that there was a 62.5% and 93% improvement in appearance, respectively. Side effects were present in 68.7% of people with hydroquinone use, versus 6.2% with ascorbic acid. Despite hydroquinone being the better performer, vitamin C may have a role to play in the treatment of melasma, since it is mostly devoid of any side effects.

Note: Vitamin C’s most active and well-studied form is known as ‘L-ascorbic acid’ and is present as ascorbate, a water-soluble molecule, in most biologic settings. So make sure to look for ‘L-ascorbic acid’ or ‘ascorbic acid’ on product labels (with or without the ‘L’ – they are the same compound, just the former is more descriptive). Finally, you want to aim for the percentage of vitamin C to be between 10 and 20% (for the greatest effect).

P.S. Vitamin C is a great anti-ageing skincare product since it is also required for collagen production, so in combination with a retinoid say goodbye to those fine lines! For more information on vitamin C and how to use it in combination with a retinoid, see this post.

Hydroxy acids for dull skin

So one day you woke up and realised your youthful glow was no longer there….your skin appears dull and tired. As we age our epidermis (top layer of the skin) gets thicker. Skin turnover slows down and as a result we see an accumulation of skin cells on the surface of our skin. This build up makes it harder for the skin to reflect light, hence the dull appearance.

To increase cell turnover and get that glowing skin back we are going to want to use hydroxy acids such as glycolic acid, salicylic acid or lactic acid. Topical acids have also been show to stimulate fibroblasts to produce collagen.
