Retinol is one of the most powerful ingredients in skincare and is known for its incredible anti-aging and skin-renewing benefits. While it’s not the easiest product to incorporate into your routine, its ability to improve fine lines, pigmentation, and elasticity makes it a must-have in the beauty world.

If you’re unsure how to use retinol, its side effects, or what results to expect, skincare expert Dr. Muneeb Shah, shares key tips on starting retinol the right way—without irritation. However, not all skin types tolerate retinol well. Depending on the concentration, it may cause irritation, and it shouldn’t be mixed with certain ingredients.

Keep reading to discover how to apply retinol, its benefits, potential side effects, and expert tips for flawless skin.

What Is Retinol?

Retinol is a form of vitamin A that speeds up cell turnover, boosting collagen production and improving skin texture. It helps with:

  • Fine lines & wrinkles
  • Acne & breakouts
  • Uneven skin tone
  • Dullness & pigmentation

Benefits of Retinol

  • Controls Oily Skin & Fights Acne – Retinol regulates oil production, helping to minimise breakouts and improve skin texture.
  • Reduces Wrinkles & Fine Lines – Retinol helps prevent and smooth out existing signs of aging.
  • Brightens Dull Skin – It exfoliates at a cellular level, promoting fresh, radiant skin.

How To Prevent Skin Irritation From Retinol?

Starting retinol the right way is key to avoiding irritation. The best approach? Follow expert advice. One of the top dermatologists sharing trusted tips is Dr. Muneeb Shah—a recognised skincare expert with over 10 million followers on Instagram and TikTok.

How to Apply Retinol the Right Way

“The benefits of retinol become evident after at least two months of consistent use,” explains Dr. Muneeb Shah. To start using retinol without irritation, follow these expert-approved steps:

  • Start slowly by applying retinol every three nights, then gradually increase frequency as your skin adjusts.
  • Use the right amount—a pea-sized portion is enough for the entire face. Apply evenly to avoid irritation.
  • Moisturise before and after application if you are new to retinol. Once your skin builds tolerance, apply moisturizer afterwards.
  • Avoid the eye area, as the skin is thinner and more sensitive than the rest of the face.

How Long Does Retinol Take to Work?

Retinol is not a quick fix. It typically takes:

  • 12 weeks to see improvements in acne.
  • Up to six months for visible changes in pigmentation, sun damage, and fine lines.
