How long will it take to see the results of retinaldehyde?

You should start seeing results immediately after starting your retinol skincare routine. However, the best results will be achieved when you use your retinol product consistently and over time (for example, 6-12 months)—the length of time into your skin. 

How do I know if I am using the right amount of retinaldehyde?

It would help if you started using very small amounts of this active ingredient on your skin. You can then increase the amount that you apply as needed over time. Retinaldehyde products are typically used as part of a larger skincare routine that includes other anti-ageing products and sunscreen.?

After a month or so with no negative effects, you can likely use it every day if you desire. Derms also recommended just using any retinol at night. The evening is when your cell turnover is at its height and is a time of rest and repair.

Here is a list of the most common types of retinoids, how they differ from one another, and how to use them:

RETINOL: Derived from Vitamin A (also known as retinyl palmitate), this is the weakest form of vitamin A. This skincare ingredient can be found in many over-the-counter products in varying concentrations. In addition, Retinyl palmitate is found in some products marketed toward acneic skin as it may help prevent breakouts caused by inflammation by decreasing redness. Still, it is not as effective for treating acne as retinoic acid.

RETINOL: These are derived from Retinol and are a little more powerful than Retinol. The most common prescription topical called tretinoin, or Retin-A, is available in several concentrations (0.05%, 0.1%, 0.04%). It’sIt’s best to start with the lowest concentration and work your way up if needed.

RETINOIC ACIDS: These are the most potent form of vitamin A and can be found in over-the-counter products such as Differin and Renova and prescription products like Tazorac and Avage. 

They are more effective than Retinol at treating acne, but they can also dry, so they should be used only at night. I recommend that those with sensitive skin start with the lowest concentration (0.025%) first and gradually increase to the right one for you.

ALPHA HYDROXY ACIDS: AHAs can be derived from fruit (glycolic acid), milk (lactic acid), or sugar cane (malic acid). They have a smaller molecular structure than retinoids, so they can penetrate the skin more easily, leading to the exfoliation of dead skin cells. 

AHAs can improve the appearance of fine lines and wrinkles and make your complexion brighter. They also help increase cell turnover, making your pores appear smaller. These acids are the most common ingredient in anti-ageing products and can be found in everything from cleansers to serums to moisturisers. 

Alpha hydroxy acids are safe to use on all skin types, but if you have sensitive skin, it is most useful to start with a lower concentration first, as they can cause redness and dryness if used too often or at too high a concentration.

NON-RETINOLS: These include ingredients like vitamin C, peptides, and antioxidants. They are often used with retinoids to boost the product’s effectiveness. They can help keep skin from sagging, help fade pigmentation, and prevent free radical damage (which can lead to premature ageing).

Retinol can be a great anti-ageing ingredient for your skin. But it is important to know what else is in your anti-ageing products to get the best results for your complexion
