Understanding Your Skin in Your 70s
As we age, our skin undergoes several key changes that impact how we should care for it. After the age of 70, the skin's surface becomes thinner, drier, and more susceptible to damage. The cell turnover rate, which is the process of shedding dead skin cells to reveal new ones, slows down dramatically. This can lead to a dull, uneven skin tone and a buildup of dead skin on the surface.
Why a Gentle Approach is Non-Negotiable
Mature skin is less resilient and the lipid barrier, which protects against moisture loss and environmental stressors, becomes compromised. Over-exfoliating with harsh scrubs or strong chemical treatments can strip this protective barrier, leading to increased sensitivity, redness, dryness, and even micro-tears. The goal of exfoliation for a 70-year-old is not to scrub aggressively, but to gently assist the natural shedding process to reveal a brighter, smoother complexion without compromising skin health.
The Verdict: How Often Should a 70 Year Old Exfoliate?
For most people in their 70s with non-sensitive skin, once a week is the ideal frequency. If you have particularly sensitive or reactive skin, you may want to start with a bi-weekly schedule (once every two weeks) to see how your skin responds. Listen to your skin—if you notice any redness, flakiness, or irritation, reduce the frequency immediately. For those with severely dry or compromised skin, a dermatologist might even recommend less frequent exfoliation or focusing solely on hydration.
Choosing the Right Type of Exfoliant
There are two primary types of exfoliants: physical and chemical. For mature skin, the choice of exfoliant is arguably more important than the frequency.
- Physical Exfoliants: These use friction to remove dead skin cells. This includes scrubs with grains or microbeads, loofahs, and brushes. For a 70-year-old, most physical scrubs are too harsh and can cause damage. If you do opt for a physical method, a soft, damp washcloth used with gentle, circular motions is the safest option. Avoid anything with large, irregularly shaped particles, such as crushed walnut shells.
- Chemical Exfoliants: These use mild acids to dissolve the 'glue' that holds dead skin cells together. For mature skin, this is often the preferred and most effective method. Key ingredients to look for include:
- Alpha-Hydroxy Acids (AHAs): Such as lactic acid, which is known for its hydrating properties. Glycolic acid can be effective but might be too potent for some mature skin types. Start with a low concentration.
- Poly-Hydroxy Acids (PHAs): These have a larger molecular structure than AHAs, meaning they don't penetrate as deeply and are therefore the gentlest option for sensitive, mature skin. Gluconolactone is a common PHA.
A Comparison of Exfoliation Methods for Mature Skin
| Feature | Physical Exfoliation (Harsh Scrubs) | Physical Exfoliation (Gentle Cloth) | Chemical Exfoliation (AHAs/PHAs) |
|---|---|---|---|
| Mechanism | Friction with abrasive particles. | Gentle friction with a soft cloth. | Dissolves dead skin cells with acids. |
| Risk of Irritation | High. Can cause micro-tears and redness. | Very Low. Safe for most skin types. | Low (when using low concentration). |
| Best For | Not recommended for mature skin. | General, gentle surface smoothing. | Promoting cell turnover and hydration. |
| Effectiveness | Can be overly aggressive and damaging. | Mild, superficial exfoliation. | Deep but gentle renewal. |
| Side Effects | Redness, inflammation, broken capillaries. | Minimal to none. | Potential for initial tingling; irritation if overused. |
A Recommended Exfoliation Routine
- Cleanse First: Start with a gentle, hydrating cleanser to wash away any surface dirt and oil. Avoid harsh, stripping soaps. Pat your skin dry with a soft towel.
- Apply Your Exfoliant: If using a chemical exfoliant, follow the product instructions carefully. Apply a thin layer to clean, dry skin, avoiding the delicate eye area. If using a soft cloth, use a very small amount of a gentle scrub or simply the damp cloth with your cleanser.
- Rinse Thoroughly: After the recommended time (if using a chemical exfoliant), rinse your face with lukewarm water. Do not use hot water, as it can further dry out the skin.
- Moisturize Immediately: Apply a rich, nourishing moisturizer with ingredients like ceramides and hyaluronic acid to replenish the skin's moisture barrier. Applying it immediately after rinsing helps to lock in hydration.
- Use Sun Protection: After any form of exfoliation, your skin becomes more susceptible to sun damage. Applying a broad-spectrum sunscreen with at least SPF 30 every morning is essential, as mature skin is more vulnerable to UV damage. For more information on protecting mature skin from the sun, consult the Skin Cancer Foundation website.
Signs of Over-Exfoliation
It's crucial to be mindful of your skin's signals. Signs that you may be overdoing it include:
- Persistent redness or inflammation
- Increased sensitivity to other products
- A tight or 'raw' feeling
- Dry, flaky patches that don't improve with moisturizing
- Breakouts or increased oiliness, as your skin attempts to compensate for lost moisture.
If you experience any of these symptoms, take a break from all exfoliation and focus on hydrating and soothing products until your skin's barrier has repaired itself.
Conclusion: The Path to Radiance
For a 70-year-old, the path to radiant, healthy-looking skin is not about aggressive treatments, but consistent, gentle care. By limiting exfoliation to once a week and opting for a mild chemical exfoliant like a PHA or lactic acid, you can effectively help your skin shed dead cells. This considered approach minimizes the risk of irritation and damage, allowing your skin to look and feel its best. Always prioritize hydration and sun protection to support your skin’s overall health and vibrancy in your golden years.
