Retinol can make your skin more sensitive to the sun, so it's recommended to use it at night and to use sunscreen during the day to protect your skin.

Retinol for skin

Retinol is one of the most well-known skincare ingredients on the market. It’s a vitamin A derivative and a go-to skincare ingredient when it comes to diminishing fine lines and wrinkles, as well as acne. It’s important to understand the varieties of retinol, how to use it and what type is best for your skin.

If you’re curious and want to learn more about this powerful ingredient and how it works on skin, look no further.

What is retinol?

Retinol is a vitamin A derivative and an antioxidant that promotes collagen, fades dark spots, brightens dull skin and treats acne. Retinol is available over-the-counter (OTC) and is the less concentrated version of a retinoid.

Retinoids are a more potent form of vitamin A that are mainly available by prescription and may cause more skin irritation in comparison to retinol. Many refer to retinol and retinoids as the same thing, but they aren’t — the OTC version of a prescription retinoid is retinol.

What’s the difference between retinoids, retinol and Retin-A?

Retin-A and retinol are different forms of retinoids. Retin-A is the brand name for tretinoin, a prescription retinoid. Retinol needs to convert to retinoic acid on the skin to work, whereas prescription-strength Retin-A is already a retinoic acid, so it works faster. The highest strength retinol product is still a lower strength than the weakest prescription retinoid.

Consult a dermatologist to see which retinoid best fits your needs. Some popular prescription retinoids are tazarotene (Tazorac), adapalene (Differin) and isotretinoin (Accutane).

How retinol works

Most skincare ingredients work by removing the dead skin from the epidermis (outer layer of the skin), but retinol goes deep into the dermis (middle layer of your skin) to do its work.

In the dermis, retinol helps neutralize free radicals while increasing the production of collagen and elastin. The increase in collagen and elastin plumps the skin and reduces the appearance of fine lines, wrinkles and pores.

Retinol also has an exfoliating effect on the epidermis and removes dead skin, resulting in improved texture, tone and reduction of age spots and hyperpigmentation. For those with oily skin, the mild exfoliation can lead to control of excess sebum production.

Retinol can help treat acne and acne scars. Retinol forms comedolytic agents to prevent and reduce formation of papules such as blackheads, whiteheads and blemishes. For those with severe cystic acne, your dermatologist might also prescribe isotretinoin, a prescription-only retinoid. It decreases the size and formation of bacteria of sebaceous glands on the skin to reduce the formation of acne.

Benefits of retinol

Retinol is the gold standard when it comes to skincare. It’s used to help the skin by reducing:

  • Fine lines
  • Wrinkles
  • Photoaging such as sunspots, freckles and other signs of sun damage
  • Hyperpigmentation such as melasma
  • Loss of collagen
  • Large pores
  • Acne

Side effects of retinol

The Food and Drug Administration has approved retinoids for use but be cautious of some of the potential side effects. If you have dry or sensitive skin, using too much retinol may cause irritation. People with skin conditions like eczema and rosacea are generally advised against using retinol. Topical retinoids also make your skin more sensitive to the sun.

On rare occasions, use of strong prescription retinoids has been linked to swelling, hives and difficulty breathing. If you’re taking supplements containing vitamin A, consult your doctor before using any retinol products, as too much vitamin A can be toxic and may cause liver damage.

If you’re pregnant or breastfeeding, dermatologists advise against using retinol products, as they may cause birth defects.

How to use retinol

Beginners should start with OTC retinol before trying a prescription strength retinoid, as it may cause the skin to feel more sensitive and cause redness and irritation. There is no set age to start integrating retinol into your routine, but it’s best to go slow to avoid irritating the skin. It’s recommended to start with retinol a couple of times a week at night and slowly increase use to every night once your skin can tolerate it.

It’s advised to only use one product at a time containing retinol. If you’re using other active ingredients like glycolic acid regularly, it’s safe to alternate nights with retinol. Due to potential risk of sun sensitivity, retinoids should be applied at night.

If you have acne issues, dermatologists can prescribe retinoids as early as your late teens. Apply retinol consistently to see the maximum benefits; it may take up to 3 months to notice how retinol is affecting your skin.

Who can use retinol?

Almost anyone can use retinol unless you have sensitive skin or are pregnant/nursing. If you have skin concerns such as acne, dark spots, fine lines and wrinkles, you can integrate a retinol product in your skincare routine.
